Editing RCOXML Images

=Description=
The images inside .rco files are indexed in the embedded '''RCOXML''' code of the .rco container under the XML element '''ImageTree'''. See [[Resource Container (RCO)]] and [[RCOXML Coding]]

All the images inside RCO files (with a few exceptions) uses a sony image format named GIM. See [[Graphic Image Map (GIM)]] and [[GimConv]]
{{RCOXML contents PS3}}

=Image=
The values marked in red are optional, the presence of the '''unknown''' specific for PS3 can be deduced based on the "rco version" in the rco header, only exists in PS3 RCO's (PSP doesnt uses it). See [[Talk:Rcomage|rcomage talk page]]. The presence of the other optional value '''file_uncompressed_size''' can be deduced by reading the entry itself

The '''file_compression''' feature adds a compression layer over the file format (pointless for image formats that are nativelly compressed like GIM or JPG)
