*changed default settings:
*The removed '''-F''' (to use pixel_order = faster) is because all PSP GIM format uses it, so it was modifyed as one of the default settings (more info below)
{{Boxcode|content=<syntaxhighlight lang="c">
*The removed '''-R''' and the added '''-X''' are related with the order of how RGBA channels are stored in the GIM, it seems -X was useful for PSP (and -R was not useful for PSP). This options are a bit pointless anyway, you should not swap RGBA channels this way by using this options directly
*The removed '''-viewer''' is because was intended to start an official gimviewer.exe that has never been published or leaked (the program doesnt exists, so the option -viewer is pointless)
*The added '''-bpp<n>''' are the RGBA based GIM formats used on PSP, this list includes some custom formats that was not used officially by sony (but works on PSP)
*The added '''-ps3''' loads a custom option that was intended for PS3 GIM files, but is wrong (more info about this problem below)
 
==Default settings==
The default settings used in the GimConv.cfg used by rcomage are problematic for PS3... up to an exent because as mentioned in frontpage at the time you write a command line for GimConv.exe you can write a long line with lot of settings (that are going to override any default setting you consider is problematic or critical for what you want to achieve)
 
The real problem is when you write a short command line for GimConv.exe (without overriding any default settings), by doing this you are using all the default settings... and this breaks GIM files for PS3

===Default settings Talk===
*added options:
*'''pixel_order'''
{{Boxcode|content=<syntaxhighlight lang="c">
**Originally (in the GimConv.cfg released by sony, intended for PS3) it was set to '''normal''' (this matches with the GIM formats used in PS3). For rcomage was changed to '''faster''' because all the GIM formats in PSP uses it
**There is not a way to choose a default value for '''pixel_order''' that fits with the requirements of all known GIM formats, because one way or the other we are breaking some GIM files (either PSP or PS3), the solution is to override this setting in every "option" you want to use (more info below)
**In short... this change causes an small harm to PS3 GIM formats, but considering there is not really a single solution to fix this problem... is ok like this
 
*'''limit_image_width''' and '''limit_image_height'''
**Originally (in the GimConv.cfg released by sony, intended for PS3) both was set to '''4096''' pixels. For rcomage was changed to '''512''' because the size of the PSP screen is way smaller than PS3 (actually PSP screen is way smaller than 512 but it seems the values of this size restrictions are adjusted to an strict rule of proportions of width x height)
**This problem affects all images bigger than 512 pixels converted by GimConv.exe GIM2PNG, GIM2GIM, PNG2GIM (and any other supported input image format to GIM). If the image is bigger than 512 it will be scaled down and the output image will have 512 pixels in one of its proportions (either width or height)
**This settings allows to use the value '''off''' (to disable the image size restrictions ?) but when using it returns a '''WARNING : too large image size <width>x<height>''' (even with tiny images), it looks like it has a problem when geting the size so is not a good idea to disable this size restriction, instead is better to use the value '''4096''' that works fine and is what sony was using originally for PS3
**As explained before... this problem can be bypassed by overriding this setting, either from command line or editing the file GimConv.cfg to create a custom option with the size values specific for PS3
**Some GIM examples from PS3 with images bigger than 512 pixels in '''explore_plugin_full.rco''':
***'''tex_playing.gim''' (30x900 pixels) https://www.psdevwiki.com/ps3/File:2rjGdbe
***'''tex_playing_shadow.gim''' (30x900 pixels)
***'''tex_opt_obi.gim''' (660x6 pixels)
**Some GIM examples from PS3 with images bigger than 512 pixels in '''custom_render_plugin.rco''':
***'''tex_ps3logo.gim''' (1200x128 pixels)
***'''tex_scelogo.gim''' (1024x64 pixels)
**Some GIM examples from PS3 with images bigger than 512 pixels in '''sysconf_plugin.rco''':
***'''tex_arrow_anim.gim''' (120x2280 pixels)
***'''tex_arrow_anim_shadow.gim''' (120x2280 pixels)
***'''tex_sce_logo''' (1024x64 pixels)
**Some GIM examples from PS3 with images bigger than 512 pixels in '''ycon_manual_plugin.rco''':
***'''tex_guide.gim''' (520x200 pixels)
 
*'''output_sequence'''
**Originally (in the GimConv.cfg released by sony, intended for PS3) it was set to '''on'''. For rcomage was changed to '''off'''. I dont really know why, in my tests this setting doesnt changes anything (setting it to either on/off results in the same output files), actually i have it enabled just incase eventually i find is doing something extra (and because originally was enabled by sony), but by now nothing, nada
 
*'''format_endian'''
**Originally (in the GimConv.cfg released by sony, intended for PS3) this was added by sony as a "override default settings <abbr title="this is one of the cases where sony doesnt wants to modify his old code and instead they adds some kind of patch that overrides the old code">patch</abbr>" applyed over GimConv.cfg (a section named '''PS3 OSD default settings''') with the value '''format_endian = big'''. For rcomage it was removed (so by default it loads '''format_endian = little''' instead, that appears some lines before in GimConv.cfg)
**This is ovbiouslly a problem for PS3, but again there is not a single way to preconfigure this setting to fill the requirements of all GIM formats. PSP needs "little", and PS3 "big", this needs to be overrided inside the "options" specific for each GIM format... or with a long command line specifying this overrides
 
*'''pixel_order'''
**Originally (in the GimConv.cfg released by sony, intended for PS3) this was added by sony as a "override default settings <abbr title="this is one of the cases where sony doesnt wants to modify his old code and instead they adds some kind of patch that overrides the old code">patch</abbr>" applyed over GimConv.cfg (a section named '''PS3 OSD default settings''') with the value '''pixel_order = normal'''. For rcomage it was removed (so by default it loads '''pixel_order = faster''' instead, that appears some lines before in GimConv.cfg)
**PSP needs to use "faster", and PS3 needs "normal", so again, this needs to be overrided inside the "options" specific for each GIM format... or with a long command line specifying this overrides
 
*'''pixel_channel'''
**Originally (in the GimConv.cfg released by sony, intended for PS3) this was added by sony as a "override default settings <abbr title="this is one of the cases where sony doesnt wants to modify his old code and instead they adds some kind of patch that overrides the old code">patch</abbr>" applyed over GimConv.cfg (a section named '''PS3 OSD default settings''') with the value '''pixel_channel = default'''. For rcomage it was removed (so by default it loads '''pixel_channel = default''' that appears some lines before in GimConv.cfg). In other words, sony overrided pixel_channel with the same value. This setting is pointless, is not doing anything
**So the removal made for rcomage is not causing any change
 
*'''image_format'''
**Originally (in the GimConv.cfg released by sony, intended for PS3) this was added by sony as a "override default settings <abbr title="this is one of the cases where sony doesnt wants to modify his old code and instead they adds some kind of patch that overrides the old code">patch</abbr>" applyed over GimConv.cfg (a section named '''PS3 OSD default settings''') with the value '''image_format = rgba8888'''. For rcomage it was removed (so by default it loads '''image_format = default''' instead, that appears some lines before in GimConv.cfg)
**This is a must to override, is one of the most critical settings, there are several values that are supported by PSP and PS3 (index4, index8, rgba5551, rgba4444, rgba5650, rgba8888, dxt5... and maybe more)
**So the removal made for rcomage is not causing any harm, is needed to override this setting anyway

*'''-ps3'''
==PS3 problems as a consequence of this custom configuration==
**Biggest problem when using this option is you are going to load all the default settings, and there are some default settings that results in a GIM file incompatible with PS3
**The second problem related with this is wrong in concept, because inside PS3 RCO files are used (at least) 2 different GIM formats (that needs to be build by using different GIM settings), to make this problem even worse in most of the RCO files from PS3 firmware are included GIM files build with different GIM formats... so aplying a single collection of settings for all the GIM files inside a single RCO doesnt works ! (you can be sure some are going to be broken... becaue there are 2 GIM formats you are going to have broken a group of them... or the other)
**Is not compatible with how rcomage automatizes the PNG-to-GIM conversions (for the same reason explained in the line above), with the actual code of rcomage is imposible to automatize the PNG-to-GIM conversions
**"format_style = ps3". For some reason sony implemented this "tag" at the time of coding GimConv.exe '''but is not used in PS3 GIM files !''', actually the GIM files for PS3 uses the tag "psp"


*'''-bpp4, -bpp8, -bpp16, -bpp16a, -bpp16p, -bpp32'''
*'''image max sizes'''
**Are the GIM formats used in PSP, keep in mind this definitions are not including some critical settings that are hardcoded in GimView.cfg as defaults (such the endianess)
The settings for '''limit_image_width''' and '''limit_image_height''' that was changed to 512 pixels for rcomage (but originally was 4096 pixels) causes a problem when converting images bigger than 512 because are going to be resized down to 512 (is the max width of a PSP scren because rcomage initially was intended for PSP)
**All this options are optionals anyway, so is not causing any harm to PS3 compatibility, if you dont need them simply dont use them


*'''The other removed options'''
The problem happens when extracting images with GIM to PNG conversion (in both, rcomage and rcomagegui)... all images will be checked for his size and biggers than 512 will be resized down preserving the aspect ratio (so the resulting image is not deformed, but the size and image quality is reduced in the extraction process)
**Doesnt have much importance, could cause problems depending in what you have for default settings in the lines at top of GimView.cfg you should not use this options directly or individually


=GimConv.cfg notes (official version)=
Also happens in the PNG to GIM conversion, when trying to compile a .rco by using as source PNG images bigger than 512 the resulting GIM will contain the image resized to 512
This is the configuration file released by sony as part of the [http://uk.playstation.com/ps3/support/settings/detail/linked235336/item85346/Download-PlayStation-3-Custom-Theme-Guidelines/ PS3 Custom Theme Toolbox]
Note there are some modifications made officially by sony at a later version because GimComv was initially made for PSP (those initial GimComv versions compatibles with "PSP only" probably didnt had this PS3 specific settings), but this public release of GimConv was released as part of a toolkit to build PS3 themes so it has some settings specific for PS3


This group at top on the config file are default settings (for PS3) that overrides other default settings of an older version of GimComv (for PSP). They are overwriting default values because the same option is specifyed before in the file, so the last one overrrides the previous one with the same name (and also was added a new option named '''extend_edge''' that should be PS3 specific)
*Some PS3 examples of images bigger than 512 pixels:

=Examples=
This is a sequence of image conversions that works as examples for wiki and also as an exercise for practising, the Gimconv.exe options used to create them are discussed on frontpage, -ps3rgba8888 and -ps3dxt5 are the GIM formats used in PS3, the others are just experiments
 
==BMP==
The image used for the tests has a size of 4x2 pixels because in RGBA 32bits format the color of a single pixel is stored in 4 bytes and in a hexeditor view by default there are 16 bytes in every row so one row of the image corresponds to one row of the hexeditor
 
The image is a [https://en.wikipedia.org/wiki/BMP_file_format BMP] with 32 bits color depth, and named '''4x2_CA5Exy_32bits.bmp''', you can click in the image at right in the table below and download it, the small table at left below is a wiki representation of the hexadecimal values of all the pixels

==GIM PS3 RGBA8888 multiple images merged==
It works ! better examples later
 
C:\Copy of GimConv 01>GimConv.exe NOPADD.BMP YESPADD.BMP -o multiimage.gim -ps3rgba8888 --update_fileinfo on --update_userdata on --merge_mode image
load "NOPADD.BMP"
load "YESPADD.BMP"
import "YESPADD.dat" ( 13 bytes )
save "./multiimage.gim"

==TM2 (PS1, PS2, PSP)==
GimConv.exe can convert and create TM2 files, see https://wiki.vg-resource.com/wiki/TIM2 you can get some TM2 samples here: http://www.ps2-home.com/forum/viewtopic.php?f=81&t=1197
 
The conversion from TM2 to an standard format as PNG or BMP is as easy as this:
{{Keyboard|content=<syntaxhighlight lang="bash">GimConv.exe IGR_BG.TM2 -o IGR_BG.PNG</syntaxhighlight>}}
 
To create a TM2 mimicking the original settings from other TM2 (for replacing purposes) is not so easy because at the time of convrsion it seems are applyed some of the settings and options of GimConv.cfg
 
==AVI==
GimConv.exe can import AVI files that was created with compatible codecs (XVID works, IV41 doesnt), you can get a sample.avi here: http://techslides.com/sample-files-for-development
{{Keyboard|content=<syntaxhighlight lang="bash">GimConv.exe sample.avi -o sample.gim</syntaxhighlight>}}
{{Keyboard|content=<syntaxhighlight lang="bash">GimConv.exe sample.avi -o sample.gis -S</syntaxhighlight>}}
 
==DDS==
See: [[Multimedia Formats and Tools#DDS]]
GimConv.exe can import compatible DDS formats, there are a lot of DDS variants though (DXT based formats are supported, and cubemap 3D textures doesnt seems to be supported). Some of the more complex featurs of GimConv.exe are directly related with DDS... in other words only can be achievd by importing a DDS file that already contains the "features" that are going to be stored in the GIM... alternativelly it looks like is posible to achieve the same goal by building the GIM from other imput formats and using the '''merge_mode''' settings, this is hardcore though and needs some scripts or additionall code to manage GimConv.exe features in a automated way
 
Some samples here: https://github.com/Jam3/parse-dds/tree/master/test/fixtures
 
{{Keyboard|content=<syntaxhighlight lang="bash">GimConv.exe test-dxt5.dds -o test-dxt5.gim</syntaxhighlight>}}
{{Keyboard|content=<syntaxhighlight lang="bash">GimConv.exe test-dxt5.dds -o test-dxt5.gis -S</syntaxhighlight>}}


*Notes:
=Versions=
**<strike>Max number of mipmaps = 8 (otherway returns the error '''WARNING : too many image level count %s''')</strike>. This restriction can be bypassed by changing the default setting: '''limit_level_count = 8''' on GimConv.cfg
*GimConv 1.20e (GIM files made around 2006)
**Cubemaps not supported
*GimConv 1.20h (GIM files made with the released PS3 theme tools... and included in rcomage)
