Editing Talk:GimConv

=gimconv.cfg custom changes made for rcomage=
[[Rcomage]] uses a GimConv configuration file edited by Zinga Burga initially to improve interoperativity with rcoedit/rcomage for PSP, and later to add compatibility with PS3

==PS3 problems as a consequence of this custom configuration==

*'''image max sizes'''
The default 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 processing images with GimConv because are resized to this max when the image is bigger

The problem happens when making a standard extraction of images with conversion to PNG (in both, rcomage and rcomagegui)... all images will be checked for his size and biggers than 512 will be resized to 512

Also happens when trying to compile a .rco by using as source PNG images bigger than 512... in the PNG--->GIM conversion process the images bigger than 512 will be resized to 512

*Some examples of images bigger than 512 pixels inside:
**explore_plugin_full.rco:
***'''tex_playing.gim''' (30x900 pixels) http://imgur.com/2rjGdbe
***'''tex_playing_shadow.gim''' (30x900 pixels)
***'''tex_opt_obi.gim''' (660x6 pixels)
**custom_render_plugin.rco 
***'''tex_ps3logo.gim''' (1200x128 pixels)
***'''tex_scelogo.gim''' (1024x64 pixels)
