A random-access sprite packer for games

Better Sprite Packer 3

Is a tool designed to pack sprites in a way they can be random-accessed.

Features

• You can randomly access any sprite (extremely fast and less memory consumption especially for sprites that aren't used!)
• Images are fully preserved even the meta data, compression is done by the image format
• Transparency is never set, if you have transparent images they will remain transparent
• Displays image meta data
• Indexes are preserved (any image removed and if its not the last element will create a placeholder 0 byte)
• Import sprites from a directory
• Import from binary
• Select the sprites you want to add (with multi-selection)
• Export to raw formats
• Export to binary
• Search an image by it's imdex
• Modern, clean looking
• Made in Kotlin programming language
• Works on Windows, Mac, and Linux
• Supports PNG, JPEG, and GIF

Info

The programs exports your files in a binary format in 2 files

1. main_file_sprites.dat (this is where all of the image data is kept)
2. main_file_sprites.idx (this is the meta data that contains meta information)

Format

1. main_file_sprites.dat

   • signature: "bsp" (3 bytes)
   • image: byte[] (variable length)

2. main_file_sprites.idx

   • dataOffset: 24uint
   • dataLength: 24uint
   • offsetX: ushort
   • offsetY: ushort
