In this thread I will share with you my experience with high resolution GPI files and modifying a GPH file to get a correct display of them.
The first time I took notice of the possibility (and problematic) of hires GPI files was with the IndyCar Series 2017 mod by rracunis. Driver images, gridcars, teamlogos and weather images seemed to be corrupt as I got only garbage display. But rracunis explained to me that the files are not corrupt but high resolution. As I was not the only one with display problems, I added standard resolution GPIs. For the NTT Indycar mod 2020 I made an update including a "Teamart file resolution" selection in the CSM menu to choose between the high and the standard GPIs.
But only recently I got aware of the fact that the high resolution GPI display problem had already been solved. While I checked some downloaded files from the 2019 F1 season I discovered the 2019 Grid Cars Final by gap177 (Glenn). He provided a GP2001.gph file and remarked "If anyone has display issues in game, just copy and paste the file in the folder named 'misc' into >menudata\pc\gp2001" in the thread. I checked it and it worked! This encouraged me to examine how to create a GPH file fitting some hires GPI for the 2019 mod resp. the Indycar 2020 mod. This is described in detail below.
I have read about the GPH file some time ago in the thread Menu editing questions, where Lo2k explained
"All files describing menus are in GP4folder/MenuData/PC/GP2001 folder.
...
gpi files are stored in the images folder and are 32bit pictures (containing an alpha channel).
All menus drawings and pictures are stored in gpi files.
But not all gpis are used by the game, in fact gpis from 388 to 401 are not used cause they are already there in previous gpis.
The tool i talked about on my forum is not a gpm browser but a gpi browser, allowing preview only of all gpi files.
gph file is storing descriptions about gpi files stored in the images folder.
As madman said, you can got there Number of gpis used, gpis ID, width and height and other datas that Madman might be right about even if i never test them personnaly.
..."
The tool he is talking about is his GPI Browser 1.2 that is a great help while creating specific GPH files.
GPH file
The structure of the GPH file was not hard to understand. The following extract shows four records (you need a hexeditor to reproduce it):
You can see a full description in the GPH Offsets Widths Heights text file.
The format is double byte with lowbyte, highbyte order. A hexadecimal value 0200 (=512) is given as "00 02".
387 GPI records are included, each with a length of 46 bytes and offsets for id=0, width=6 and height=10.
Thus I get from the four records:
ID=001 (01 00), width=240 (00 f0), height=132 (b4 00)
ID=141 (8d 00), width=256 (00 01), height=213 (d5 00)
ID=142 (8e 00), width=128 (80 00), height= 56 (60 00)
ID=387 (83 01), width=200 (c8 00), height=150 (96 00)
Now I could edit the values of the GPH file with the hexeditor, but I was more comfortable with using the GPI Browser instead. To get a modified GPH file in a testing environment, I copied my complete GP4 backup folder into a GP4-test folder and directed GPI Browser to it by "Change GP4 path". Now I loaded TGA files with the desired size into the GPIs of the browser window and finished it by pressing the button "Apply all changes", to update the GPH file. As I was only interested into the new width and height of the GPI, the display of the image in the browser didn't matter. Finally I copied the new file GP4_test\MenuData\PC\GP2001\GP2001.gph to the place I wanted it to use.
Creating hires GPI for the 2019 F1 mod
For the 2019 mod V2.2 compiled by MSchumi24 I wanted to test the following hires GPI files:
1) 2019 Grid Cars Final by gap177 (Glenn Perk). Glenn had also provided the standard grid car files of the mod.
2) files 2019 by augustogibim, Grid Cars + Pitcrew&Engineers + Driver Art+ Garages 2019
3) Visors + driver arts + logos + gridcars 2019] by rracunis. He has also provided the standard driver and teamlogo files of the mod.
First I made some changes in the 2019 CSM mod structure to support hires and standard GPI. I did this using the %texres% variable that is defined in the Settings\GlobalVars.ini file for texture resolution selection to support GPI file resolution also. %texres% can have the values "Hi" and "Std". In the "Teamart" subfolders "Drivers", "Gridcars", and "Logos" I created new subfolders "Hi" to contain the new hires GPI files.
In the "2019.csm" file I changed the following line of section [Files]:
In the Settings\swap.ini files section [Swapfiles] I added the line
1) 2019 Grid Cars Final][/url] by gap177 (Glenn Perk).
This release had GPI files for gridcars in two versions: drivernames.gpi for CSM, gpi-number.gpi for Non-CSM. TGA files were not included, but a GPH file. I did a hexeditor compare with the original GPH file to see what was changed.
Logos (default 80 00, 60 00 = 128x96px)
with new width 00 02 = 512px, height 80 01 = 384px for GPI ID numbers
with new width 90 01 = 400px, height 77 00 = 119px for GPI ID numbers
This GPH was not only designed for hires gridcars, but for hires teamlogos also, though GPI files for logos were not included. The gridcar height of 119 was unexpected but worked. The usual value would have been 99.
I copied the GPH file into folder Menu and renamed it to "Hi_GP2001.gph".
Then I copied the new hires gridcar GPI files from Glenn into the "Gridcars" subfolder "Hi". Here I had to be careful and check if the team names fit in the mod. Three names had to be adjusted: "Alfa Romeo" to "AlfaRomeo", "Racing Point" to "RacingPoint" and "Red Bull" to "RedBull". Finally I copied the file "team11.gpi" from folder "Std" to folder "Hi".
Now I started the mod with "Texture resolution" set to "Hi" and "Race Type" set to "Non Championship Race" to get the grid displayed. After starting a race, I admired the beautiful hires gridcars. Back to the main menu I selected a driver. The teamlogo was not shown in the background because of the wrong size in the GPH, but that was no big deal. After I quit GP4 and started the mod again with "Texture resolution" set to "Standard", the teamlogo - in standard size - was shown correctly.
2) "files 2019" by augustogibim, Grid Cars + Pitcrew&Engineers + Driver Art+ Garages 2019
From this archive I used "Drivers 2019.rar" and "Gridcars 2019.rar". Included were only TGA files, no GPI or GPH. The files were provided in two versions: one for 4:3 and one for widescreen. I took the 4:3 images, but the process is the same with the widescreen part. Driver images had a size of 512x512px while the gridcars were special: they had a view from above and a size of 1200x300px. From TGA I created GPI using Slimtex. The names of the drivers were only 3 characters long, so the drivers GPI files had to be renamed to fit the mod. The gridcar names were almost perfect, only "racingp" had to be changed to "racingpoint".
Now I created the GPH file. First I copied the default GP2001.gph file from my backup folder into my GP4-test folder MenuData\PC\GP2001\ to have a clean start. Then I loaded a driver TGA file in GPI Browser over all driver GPI (33, 55-56, 60-64, 66, 68, 70, 72, 74-75, 193, 268-273, 304) and a gridcar file over all gridcar GPI (178-179,182-190). Finally I pressed "Apply all changes", copied the modified GPH to the 2019 mods Menu folder and renamed it to "Hi_GP2001.gph". A look into the GPH file showed that the driver GPI width and height were both set to 00 02 (=512) while the gridcar GPI width and height are b0 04 (=1200) resp. 2c 01 (=300).
I replaced the files in Teamart\Drivers\Hi and Teamart\Gridcar\Hi with the new GPI. Now I started the mod with "Texture resolution" set to "Hi" and and "Race Type" set to "Non Championship Race" and tested the resulting displays.
3) "Visors + driver arts + logos + gridcars 2019" by rracunis.
I used the "Gridcars 1.0" (HD and Normal, GPI and TGA files) and the "Teamart 2019" (GPI only) with hires "Drivers" and "Logos" providing two hires versions, one in the subfolder HD. The normal gridcars had a size of 200x49px as usual, while the HD gridcars had the size 400x99px. Drivers were sized 512x512px, which was also true for the HD logos. The latter surprised me a bit. Because the standard size for teamlogos is 128x96px I expected something like 512x384px (4x).
In "Drivers" and "Logos" I created one TGA file using Slimtex. Then I generated the GPH file using GPI Browser and the TGA files. Now I made a backup of the original gridcars "Std" folder and copied the GPI files into their mod folder. Finally I started the mod and tested the result.
Six driver images and eight gridcars were corrupt and the logos were not shown. The research showed: I had not updated the drivers GPI 268-273 with GPI Browser, I had forgotten to rename the gridcar names of the double word teams and I had forgotten to edit the [logos] section in the teamart.ini file. Second try after correction: drivers and gridcars ok, but logos were not shown. Something was wrong with the GPH size I suggested. I created TGA files of other sizes (400x300, 512x384), imported them with GPI Browser into the logos GPI, but it didn't work either.
Finally I gave up and used the other GPI logos from the main folder "Logos" of rracunis files that were correct displayed in Slimtex - in contrast to the HD logos. These 512x512px logos worked with a GPH size of 512x512px as well as 512x384px and I could at last enjoy the enhanced display.

Creating hires GPI for the Indycar2020 mod
The NTT Indycar mod 2020 compiled by rracunis had already got hires and lowres teamart GPI files (Drivers, Gridcars and Logos) and a "Teamart resolution" selection in the CSM menu. On my computer the hires GPI was displayed disturbed so I always had to play with low resolution ('Med'
teamart. With the implementation of the GPH file I hoped to make all the hires files visible to me.
The driver images with a hires format of 512x512px made no problem. This was different with the gridcars, logos and weather (in folder 'Data\Files\Weather\Hi' hires GPI:
Downlaod: Indycar 2020 mod teamart and weather hires update
Summary
As a conclusion of this experience I can say that it feels good to be able to see the hires GPI now.
The size of hires GPI files should in general have the same aspect ratio than the corresponding original GPIs to avoid problems.
It is good for the user if TGA files are provided in a hires GPI release.
Several questions are remaining:
a) Why have some users hires GPI display problems on their computer but others do not?
b) Does a correct GPH file solve all problems or are there still users that cannot see all hires GPIs.
c) Why is it sometimes possible to display a GPI that has a size (i.e. 512x512) different from the GPH size (i.e. 400x99) and sometimes not?

The structure of the GPH file was not hard to understand. The following extract shows four records (you need a hexeditor to reproduce it):

There are some other extra areas besides the one in front of ID 142 with 480 bytes: 32 bytes each in front of 9,10 and 35 , 64 bytes in front of 11 and 256 in front of 43.You can see a full description in the GPH Offsets Widths Heights text file.
The format is double byte with lowbyte, highbyte order. A hexadecimal value 0200 (=512) is given as "00 02".
387 GPI records are included, each with a length of 46 bytes and offsets for id=0, width=6 and height=10.
Thus I get from the four records:
ID=001 (01 00), width=240 (00 f0), height=132 (b4 00)
ID=141 (8d 00), width=256 (00 01), height=213 (d5 00)
ID=142 (8e 00), width=128 (80 00), height= 56 (60 00)
ID=387 (83 01), width=200 (c8 00), height=150 (96 00)

Finally I copied the new file GP4_test\MenuData\PC\GP2001\GP2001.gph to the place I wanted it to use.
Creating hires GPI for the 2019 F1 mod
For the 2019 mod V2.2 compiled by MSchumi24 I wanted to test the following hires GPI files:
1) 2019 Grid Cars Final by gap177 (Glenn Perk). Glenn had also provided the standard grid car files of the mod.
2) files 2019 by augustogibim, Grid Cars + Pitcrew&Engineers + Driver Art+ Garages 2019
3) Visors + driver arts + logos + gridcars 2019] by rracunis. He has also provided the standard driver and teamlogo files of the mod.
First I made some changes in the 2019 CSM mod structure to support hires and standard GPI. I did this using the %texres% variable that is defined in the Settings\GlobalVars.ini file for texture resolution selection to support GPI file resolution also. %texres% can have the values "Hi" and "Std". In the "Teamart" subfolders "Drivers", "Gridcars", and "Logos" I created new subfolders "Hi" to contain the new hires GPI files.
In the "2019.csm" file I changed the following line of section [Files]:
TeamArt =Teamart\teamart-%texres%.ini
and in the folder "Teamart" I created two new INI files: "teamart-std.ini" with the same content as "teamart.ini" and "teamart-hi.ini". In "teamart-hi.ini" I replaced "Drivers\" with "Drivers\%texres%\", "Logos\" with "Logos\%texres%\" and "Gridcars\" with "Gridcars\%texres%\". In the 2019 F1 mod the teamart helmets were disabled by using empty GPI files.In the Settings\swap.ini files section [Swapfiles] I added the line
File20 =Menu\%texres%_GP2001.gph,MenuData\PC\GP2001\GP2001.gph
Now, if texture resolution is set to "Hi" in the CSM menu, the GPH file was swapped.1) 2019 Grid Cars Final][/url] by gap177 (Glenn Perk).
This release had GPI files for gridcars in two versions: drivernames.gpi for CSM, gpi-number.gpi for Non-CSM. TGA files were not included, but a GPH file. I did a hexeditor compare with the original GPH file to see what was changed.
Logos (default 80 00, 60 00 = 128x96px)
with new width 00 02 = 512px, height 80 01 = 384px for GPI ID numbers
31 00 = 49
32 00 = 50
33 00 = 51
8e 00 = 142
8f 00 = 143
90 00 = 144
91 00 = 145
92 00 = 146
93 00 = 147
94 00 = 148
95 00 = 149
Gridcars (default: C8 00, 31 00 = 200x49px)with new width 90 01 = 400px, height 77 00 = 119px for GPI ID numbers
b2 00 = 178
b3 00 = 179

b7 00 = 183
b8 00 = 184
b9 00 = 185
ba 00 = 186
bb 00 = 187
(bc 00 = 188 for team11 is intentionally not changed)
bd 00 = 189
be 00 = 190This GPH was not only designed for hires gridcars, but for hires teamlogos also, though GPI files for logos were not included. The gridcar height of 119 was unexpected but worked. The usual value would have been 99.
I copied the GPH file into folder Menu and renamed it to "Hi_GP2001.gph".
Then I copied the new hires gridcar GPI files from Glenn into the "Gridcars" subfolder "Hi". Here I had to be careful and check if the team names fit in the mod. Three names had to be adjusted: "Alfa Romeo" to "AlfaRomeo", "Racing Point" to "RacingPoint" and "Red Bull" to "RedBull". Finally I copied the file "team11.gpi" from folder "Std" to folder "Hi".
Now I started the mod with "Texture resolution" set to "Hi" and "Race Type" set to "Non Championship Race" to get the grid displayed. After starting a race, I admired the beautiful hires gridcars. Back to the main menu I selected a driver. The teamlogo was not shown in the background because of the wrong size in the GPH, but that was no big deal. After I quit GP4 and started the mod again with "Texture resolution" set to "Standard", the teamlogo - in standard size - was shown correctly.
2) "files 2019" by augustogibim, Grid Cars + Pitcrew&Engineers + Driver Art+ Garages 2019
From this archive I used "Drivers 2019.rar" and "Gridcars 2019.rar". Included were only TGA files, no GPI or GPH. The files were provided in two versions: one for 4:3 and one for widescreen. I took the 4:3 images, but the process is the same with the widescreen part. Driver images had a size of 512x512px while the gridcars were special: they had a view from above and a size of 1200x300px. From TGA I created GPI using Slimtex. The names of the drivers were only 3 characters long, so the drivers GPI files had to be renamed to fit the mod. The gridcar names were almost perfect, only "racingp" had to be changed to "racingpoint".
Now I created the GPH file. First I copied the default GP2001.gph file from my backup folder into my GP4-test folder MenuData\PC\GP2001\ to have a clean start. Then I loaded a driver TGA file in GPI Browser over all driver GPI (33, 55-56, 60-64, 66, 68, 70, 72, 74-75, 193, 268-273, 304) and a gridcar file over all gridcar GPI (178-179,182-190). Finally I pressed "Apply all changes", copied the modified GPH to the 2019 mods Menu folder and renamed it to "Hi_GP2001.gph". A look into the GPH file showed that the driver GPI width and height were both set to 00 02 (=512) while the gridcar GPI width and height are b0 04 (=1200) resp. 2c 01 (=300).
I replaced the files in Teamart\Drivers\Hi and Teamart\Gridcar\Hi with the new GPI. Now I started the mod with "Texture resolution" set to "Hi" and and "Race Type" set to "Non Championship Race" and tested the resulting displays.
3) "Visors + driver arts + logos + gridcars 2019" by rracunis.
I used the "Gridcars 1.0" (HD and Normal, GPI and TGA files) and the "Teamart 2019" (GPI only) with hires "Drivers" and "Logos" providing two hires versions, one in the subfolder HD. The normal gridcars had a size of 200x49px as usual, while the HD gridcars had the size 400x99px. Drivers were sized 512x512px, which was also true for the HD logos. The latter surprised me a bit. Because the standard size for teamlogos is 128x96px I expected something like 512x384px (4x).
In "Drivers" and "Logos" I created one TGA file using Slimtex. Then I generated the GPH file using GPI Browser and the TGA files. Now I made a backup of the original gridcars "Std" folder and copied the GPI files into their mod folder. Finally I started the mod and tested the result.
Six driver images and eight gridcars were corrupt and the logos were not shown. The research showed: I had not updated the drivers GPI 268-273 with GPI Browser, I had forgotten to rename the gridcar names of the double word teams and I had forgotten to edit the [logos] section in the teamart.ini file. Second try after correction: drivers and gridcars ok, but logos were not shown. Something was wrong with the GPH size I suggested. I created TGA files of other sizes (400x300, 512x384), imported them with GPI Browser into the logos GPI, but it didn't work either.
Finally I gave up and used the other GPI logos from the main folder "Logos" of rracunis files that were correct displayed in Slimtex - in contrast to the HD logos. These 512x512px logos worked with a GPH size of 512x512px as well as 512x384px and I could at last enjoy the enhanced display.
2019 F1 mod teamart hires update
In the original mod the authors of the standard files are:
Teamart
-Drivers rracunis
-Helmets (nohelmets)
-Gridcars Glenn Perk
-Logos rracunis
It is therefore reasonable to take the hires files from the same authors and update the mod with them in the way I explained above. As the rracunis files are already loaded, all I had to do was to take the backup "Std" folder for gridcars and put Glenn's hires gridcars into the "Hi" folder. I could use the same GPH as above because the GPH size 400x99px worked with Glenns hires gridcars also.Download:2019 F1 mod teamart hires update

While I was successful with the gridcars GPH size 400x99 (90 01, 63 00) over a 512x512 GPI file, all my effort to get the logos and/or weather hires files displayed properly was in vain. Finally I decided to replace those GPIs. Fortunately I had got weather files from rracunis for a previous Indycar mod. The hires logos I made myself. This worked:

Summary
As a conclusion of this experience I can say that it feels good to be able to see the hires GPI now.
The size of hires GPI files should in general have the same aspect ratio than the corresponding original GPIs to avoid problems.
It is good for the user if TGA files are provided in a hires GPI release.
Several questions are remaining:
a) Why have some users hires GPI display problems on their computer but others do not?
b) Does a correct GPH file solve all problems or are there still users that cannot see all hires GPIs.
c) Why is it sometimes possible to display a GPI that has a size (i.e. 512x512) different from the GPH size (i.e. 400x99) and sometimes not?

that's awesome from you Peter, thank you very much for this 
Can grid cars be in hires?
I made these at 1200 x 300px
I made these at 1200 x 300px
The 1200x300 format does not seem to be the best choice. Compare them with the downsized 400x99, which is the more usual hires format. The latter is looking better.
The third image is an hires example with 400x99 images from Glenn.

GPH record: horizontal and vertical stretch values
Until now I have only used the ID with the width and height values. But there is still more to be discovered. As an example I will examine the record of the driver01 GPI in the GPH file:
ID=33, length = 46 byte (00 to 45)
A very useful hint was once given by madman271 in the GP4Italia forum:
Remind me if I'm wrong.
Menu textures perhaps stored in *.gpi files. You can obtaining *.gpi information from *.gph or *.gpm file (these files seem to be identical). I'm just looking on the *.gph file and there was stored the *.gpi ID number, dimension (width and height), as well as position and dimension in screen in float values. These values similar like when we using UV mapping, mean minimum value is 0.0 and maximum value is 1.0.
Hope this is help.
First I am searching for "floating point hexadecimal" and found the IEEE-754 Floating Point Converter.
Here into the field "Hexadecimal Representation" I wrote 0x3f800000 to see which value 3f80 is representing. Result = 1.0 .
Okay, then if the values are between 0 and 1 as madman271 guessed, what will be the hexadecimal representation of 0.5? Result = 0x3f00.
The two values 1 (80 3f) and 0.5 (00 3f) should be enough for a first test. I created a framed 33.gpi and checked all combinations of this two values in the four record positions using a hex editor. While the last two positions (40-41, 44-45) had effects on the display of the GPI file, the first two did not. Depending on the last two values this is what I got:
80 3f - 80 3f, normal
00 3f - 80 3f
80 3f - 00 3f
00 3f - 00 3f
The images show, that the value 0.5 (00 3f) stretches upper resp. left half to fill the full image area.
The first value makes vertical, the second horizontal stretching.
Wouldn't it be nice to get an image not stretched but compressed in a way that it compensates the widescreen (16:9) stretching?
If a value between 0 and 1 makes a stretching, can I make a compression with a value greater than 1?.
Lets evaluate: to come down from 16:9 to standard 4:3 one has to multiply with 3/4. The GPH stretching factor is the reciprocal value 4/3 (when 0.5 does double stretching, a value 2.0 = 00 40 should do compressing to half size). My wanted value is 4/3 = 1.3333..., thus I put 1.3333 into the floating point converter and get the hexadecimal representation 0x3faaa993. This gives me "aa 3f" (or "ab 3f", that makes not a great difference) as horizontal stretching value. I put it into the GPH file:
80 3f - aa 3f
Yes, it works! But what about the white area at the right?
Well, I had made a white 1px frame aroung the driver image. Apparently the rightmost 1px column is taken to fill the space that is left by the compression.
I deleted that column (I always use Paint.NET for tga editing) to transparency and displayed the image again, this time in 16:9 screen resolution:
80 3f - aa 3f widesrceen stretch compensated
Compare this with the normal not compensated widescreen display:
80 3f - 80 3f, widescreen stretched
This is a satisfying result and I will now go on and update the GPHUpdater tool to support the stretching values.
