[REPUBLISH] Koishi’s Extractor BlackCat.1

  1. Now supports exporting as GIF animation.

    • Ticked frames can be exported as GIF animation if ticking 1 or more frames.
    • GIF animation speed can be set in Software Settings. Range is from 10ms to 3,000ms.
    • As GIF only supports 256 colors, the animation needs to be indexized when generating GIF. Therefore when images are big or frames are many, the generating speed would be slow (proportional to the 4th powers of the image size)
  2. Localization

    • Logo can be freely set. Put BMP of 150 x 40 into the “support” folder in the output directory and name as “LOGO.BMP”. Then software LOGO will display the file.
    • If there being no logo (files) it will display Koishi.
    • Background picture of the canvas can be set. Put one PNG of any size into the “support” folder and name as “BACK.PNG” and then the background of the canvas will display the faded selected picture.
    • If there being no this picture nothing will be displayed
    • The canvas background color modification is now implemented
  3. Dressing Room Improvement
    - Dressing Room localization output format is now changed back to PNG and it will be much faster

    • If selecting non-zero palette and click generate NPK, only V4 IMGs of the corresponding palette will be generated. If selecting zero-th palatte, what is generated is still V6 IMGs.
    • One-Key exporting all-characters avatars mod will be also generated as selecting palettes.
    • Resource folder can be no longer modified in Dressing Room. Please go to Software Settings and modify.
    • Animation display speed is no longer so kichiku.
    • Now supports recognizing neck_k layer (some glow layers still unrecognized, wating fixing)
  4. Color Chart Functions Adding

    • Color Chart can be defaulted. There are Classic, 16 colors, 256 colors and automatic extracting from current frame or all frames of the IMG.
    • There will be alerts when defaulting to indexed sprites.
    • Color Chart display latency bug has been fixed.
  5. Other Changes

    • Bug of IMG list automatic sort function being unavailable is fixed.
    • IMG border line is a bit thicker.
    • Toolbar Tip Texts are added.
    • When using draw functions with mouses, corresponding button will be faded. Using Index Mode , IMG Comparing Mode , Playing Mode to display, corresponding button will be faded.
    • KoishiEx library now contains native BMP/GIF/PNG library! No longer depends on LibPNG!
      • Please find ZLIB and LIBBZ2 and compile by yourself and replace these two librarys before compiling this project when using non-VS2010 IDEs.
