'''G'''raphic '''I'''mage '''M'''ap ? ('''GIM''') is an image format | '''G'''raphic '''I'''mage '''M'''ap ? ('''GIM''') is an image format that allows for lot of different settings that results in lot of different GIM files that are structurally different, strictly speaking the GIM format is always the same, but generally speaking it can be said that this different GIM files are "GIM formats", the amount of GIM formats supported by PlayStation consoles is limited though (restricted by the graphic enviroment, libraries, etc...). GIM files was found in PSP and PS3 firmwares inside [[Resource Container (RCO)]] files, [[PlayStation 3 Theme (P3T)]] files, etc... See [[GimConv]] and [[Multimedia Formats and Tools#GIM]] | ||
The | The meaning of the "GIM" acronym used in this wiki ('''G'''raphic '''I'''mage '''M'''ap) is an speculative unnofficial name based in how the data is stored in the internal GIM structure, if someone finds the official codename please report back and we will change it<!-- no luck on facebook https://www.facebook.com/hhhhhyuk? --> | ||

This article is marked for rewrite/restructuring in proper wiki format. You can help PS3 Developer wiki by editing it. |
Description[edit | edit source]
Graphic Image Map ? (GIM) is an image format that allows for lot of different settings that results in lot of different GIM files that are structurally different, strictly speaking the GIM format is always the same, but generally speaking it can be said that this different GIM files are "GIM formats", the amount of GIM formats supported by PlayStation consoles is limited though (restricted by the graphic enviroment, libraries, etc...). GIM files was found in PSP and PS3 firmwares inside Resource Container (RCO) files, PlayStation 3 Theme (P3T) files, etc... See GimConv and Multimedia Formats and Tools#GIM
The meaning of the "GIM" acronym used in this wiki (Graphic Image Map) is an speculative unnofficial name based in how the data is stored in the internal GIM structure, if someone finds the official codename please report back and we will change it

0x05 (Palette)[edit | edit source]
The palette block is used for indexed color formats (index4 index8 index16 index32), to create a GIM with a palette is needed to use as input an image that already contains a color palette (such BMP or DDS)
The concept of "palette" is a bit confusing because here is used for two different things, the block 0x05 is codenamed palette as a general concept, the file structure is the same than the block 0x04 (image), both ends with the user_data (optional), then it comes an index to indicate how many palettes there are and its offsets (usually only one palette), and then starts an area where are stored the pixel colors... this area to store pixel colors is the real palette in design slang but to avoid this name confussion we can call it the colormap
- The differences in between block 0x04 (image) and block 0x05 (palette) are minor, only differs in how are used
- The palette (block 0x05) is located before the image (block 0x04) in the block hierarchy of the GIM structure, doesnt seems to be anything that connects them, other than the fact that "the palette goes first"
- The palette stores the "colormap", and the image stores an "indexmap" (and every index value in the image loads a color from the palette colormap)
- The palette only allows for palette_format = rgba8888 rgba4444 rgba5551 rgba5650
- The "colormap" is stored as an image of 256x1 pixels (image_width = 0x100 image_height = 0x1) and allows to store 256 colors
- The "colormap" has a reserved bytes size in the GIM file structure based on the palette format, 0x400 bytes in rgba8888, 0x200 in rgba4444, etc...), if the number of colors is smaller than 256 the "colormap" area will have some bytes filled with zeroes (not used)
- The palette is stored as level_type = MIPMAP2
0xFF (Fileinfo)[edit | edit source]
This block only exists if the GIM is build using the setting update_fileinfo = on. Initially in old PS3 firmwares all the GIM files was made this way, eventually sony stopped using this setting and GIM files was updated/replaced by new ones without this fileinfo block. But there are many GIM files inside latest PS3 firmware that contains this fileinfo block (are GIM files made years ago and never was updated, this can be seen in the timestamps stored in them around 2005/2006)
