GRF Editor v1.5.1

http://rathena.org/board/files/file/2766-grf-editor/

  • Sprite Editor : a simple sprite editor with powerful features. Semi-transparent images can be added, you can easily change the order or replace images, etc. This tool can convert images in the wrong type by showing you multiple solutions (merging a new palette, dithering the image by using current palette, using the closest color, and a few more). It isn't entirely finished yet, more features will be added.
  • Find errors : detects simple mistakes such as files that shouldn't be placed in there (.svn, thumbs.db), empty files, hidden files, spr or act file that doesn't have its corresponding match, duplicate files and a few more.
  • Validate Grf : reads the entire GRF to detect wrongly compressed files. The files that couldn't be read are shown at the end.
  • Flat maps maker : generates flat maps from .gat and .rsw files. Useful to generate WoE maps or to fasten up the loading time.
  • Patch maker : generates a GRF patch based on two different GRFs.
  • Hash viewer : shows the hash code (both CRC32 and MD5) for files.
  • Image converter : converts an image to any format requested (BMP, PNG, JPG, TGA).
  • GrfCL : used to create batch files (.bat) which can automate tasks on GRF files. See the content in GrfCL.rar in the download for more information. This tool can be customized from the sources as well.
  • Palette recolorer : creates new sprites by changing their colors. I will add some documentation or a tutorial later if necessary.
  • Client Database Editor : allows modifications of the database client files (txt and lua) with easy and simple tools. Work in progress.
