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 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)

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)

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

  • Some PS3 examples of images bigger than 512 pixels:
    • 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)
