= | =Usage= | ||
The command line help of GimConv.exe displays a very limited list of options with an small explain, some are generic for the tool usage, and others works as lables that loads one option or a group of options from the config file (GimConv.cfg) | |||

By specifying an option, or a group of options from command line by his labels (using the names that appears in the help screen, or using the names that appears inside the GimConv.cfg file) | |||
{{Keyboard|content='''gimconv.exe test.png -o test.gim --DXT'''}} | |||
*Note the DXT label at the bottom of GimConv.cfg is composed by 3 options: | |||
**Warning: the option -DXT has been deleted in the GimConv.cfg provided with rcomage, for more detailed changes in that custom GimConv.cfg file see the {{talk}} page | |||
{{Boxcode|content=<syntaxhighlight lang="c"> | |||
option -DXT { | |||
pixel_order = default | |||
pixel_channel = default | |||
image_format = default | |||
} | |||
</syntaxhighlight>}} | |||
---- | |||
By specifying the options strictly from command line (using the names that appears inside the GimConv.cfg file). This is the most accurate way to specify options and to have full controll of all the gim settings | |||
{{Keyboard|content='''gimconv.exe test.png -o test.gim --format_style psp --format_endian big --pixel_order normal'''}} | |||
*Note the 3 options used in the example are overriding the default settings at top of GimConv.cfg: | |||
{{Boxcode|content=<syntaxhighlight lang="c"> | |||
//---------------------------------------------------------------- | |||
// default settings | |||
//---------------------------------------------------------------- | |||
pixel_order = default // default normal faster | |||
format_style = psp // std psp ps3 | |||
format_endian = little // little big | |||
</syntaxhighlight>}} | |||
---- | |||
By sending .gim settings from rcomage.exe ---to---> gimconv.exe when compiling the .rco (see the "compile" help in [[rcomage]] page). There are 2 options in rcomage specific for this task, named: '''--gimconv-cmd''' and '''--gimconv-flags''' | |||
{{Keyboard|content='''rcomage.exe compile test.xml test.rco --gimconv-cmd ".\gimconv\gimconv.exe" --gimconv-flags "--format_style psp --format_endian big --pixel_order normal"'''}} | |||
==GimConv.cfg== | |||
This is the configuration file that defines the help screen, and contains the default values and all available options. The next example is the configuration file provided 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] | |||
<div style="height:520px; overflow:auto"> | |||

</syntaxhighlight>}} | </syntaxhighlight>}} | ||
</div> | |||
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) | ||
{{Boxcode|content=<syntaxhighlight lang="c"> | |||
//---------------------------------------------------------------- | |||

//---------------------------------------------------------------- | |||

pixel_channel = default // -R | |||
image_format = rgba8888 // --image_format rgba8888 | |||

== | ===Custom configurations=== | ||
The configuration file allows to modify the ''help'' screen of the command line by adding custom labels, or by removing useless options to make room for more custom labels, this labels can be composed of groups of options, there is no need at all to do this because doesnt really enables any new funcionallity as you can specify all the options you need one by one from command line included the hability to override default values, but is good to keep a record of the most common used formats for a console by using custom labels with intuitive names that defines the GIM format | |||
The config file supplyed by [[Rcomage]] contains some custom options for the formats that are used in PSP, some changes in the default settings that was common for PSP (included a size limit that breaks compatibility with PS3), and a group of options was added for PS3 (labeled '''-ps3''') but this group seems to use wrong options. For more info about the modifications made in the config file supplyed with [[rcomage]] see the differences in the {{talk}} page | |||
This wiki section proposes new groups of options with new label names (to be able to use a new modifyed config file without breaking the compatibility of other tools that uses rcomage as a dependency) | |||
The label names proposed here doesnt makes sense at this point, feel free to add more groups of settings with any label name following this same method, also add some info about how many images uses this format (if posible) | |||
*Inside [[explore_plugin]]_full.rco from firmware 4.70 there are 245 images, 201 of them (included the new icon tex_psn.gim) has been made by using this options: | |||
{{Boxcode|content=<syntaxhighlight lang="c"> | |||

*GIM--->GIM method (prefered) | |||
**Use gimconv with .gim files as input and output (this preserves dxt pixel info, because dxt images doesnt suffers a conversion) | |||
{{Keyboard|content='''gimconv.exe test.gim -o test.gim --format_style psp --format_endian big --image_format dxt5 --pixel_channel default --pixel_alpha default'''}} | |||
*GIM--->PNG--->GIM method (fails when there is involved a DXT conversion because DXT conversions are lossy, works fine for rgba**** image formats): | |||
**Use rcomagegui to make an extraction of the contents '''without''' conversion of images (this way the GIM are extracted as GIM) | |||
* | **Use rcomagegui to make another extraction of the contents '''with''' conversion of images (this way the GIM are extracted as PNG) | ||
**Use gimconv to convert a PNG ---to---> GIM by the old method of test-error by trying some of the options availables that appears in gimonv.cfg | |||
**''' | **Use a hexeditor to compare the original GIM extracted in step 1 with the rebuilt GIM from your test, there is no need to make accurate comparisons, just an overview of the first 0x80 bytes of the header, and how the pixel data is ordered starting at offset 0x80 | ||
** | **When the header and pixel data seems similar make a hash comparison, original GIM and rebuild GIM should be exactly the same hash (is posible to create a GIM exactly like the original) | ||
** | |||
* | *By using GimConv.exe with the '''-S''' option | ||
**This generates a .GIS file (is a text based file that contains info about the .GIM file, included all the pixel data) | |||
{{Keyboard|content='''GimConv\GimConv.exe -S test.gim -o test.gis'''}} | |||
=GIM formats used in PS3= | |||
PS3 uses at least 2 types of GIM images, both included inside rco's, and in some cases both types in the same rco | |||
When an .RCO contains 2 or more images that was created with different .GIM settings... it means is not posible to compile the .RCO with rcomage by using .PNG images as source (because rcomage.exe sends the GIM settings to gimconv.exe to make the PNG--->GIM image conversion and this settings are applyed to all PNG images) | |||
In other words, the only way to compile this RCO's is in 2 steps. In the first step is needed to make the different .GIM conversions with gimconv.exe (and all the other conversions in case exists .VAG audio a WAV2VAG conversion or a JS2VSMX for the .VSMX script). In the second step is needed to compile the .RCO with rcomage.exe by using the .GIM's .VAG's and .VSMX's as sources without any kind of file conversions | |||
Also means we have a big problem to document in wiki wich settings are used for each image (there are thousands of images so initially seems not posible), but probably they follows a rule, so the solution is to deduce or imagine the real reason of why the ps3 is using different gim formats inside the .rco's | |||

00002350 00 00 00 00 .... | |||
It seems the reason why this images are slighty different is because are ancient (has not been updated lot of firmwares ago, and uses the format from the first firmwares) | |||
As interesting details, in the footer of original files it can be seen the name and format of the original image (.tga), the windows user name, timestamp (from 2006), an the version of GimConv (an old 1.20e) | |||
The '''00 00 00 4C''' (repeated 2 times) at top of the footer in the original gim example is the size of the whole footer (usefull to make the calculation to remove the footer and update the filesize at gim header) | |||
==Speculation== | |||
Initially... it seems the gim format depends of who is the responsible of displaying them (as an example, in the link above it seems the images reported as "rare" belongs to "tex_indi_***" (are textures for the "indicator", is the information bar at top-right of xmb, are the tiny icons that appears eventually when you receive a message, etc..) | |||
<strike>Note is posible to group them based in how his names starts, all "tex_indi" belongs to indicator so should share the same gim format, even if there are more "tex_indi" inside other rco's, doesnt matters in wich .rco are located what matters is his purpose is the same (to be displayed inside the indicator)</strike> This assumption seems wrong | |||
