A simple and easy-to-use textures packer and font atlas generator.

rTexPacker is a powerful tool to package sprites or fonts into an atlas, to improve drawing performance on games.

Multiple images can be automatically organized (packed) into a single bigger image, as well as the multiple text characters of a font required by a game.

Packaging method can be configured with several option like packaging algorithm, padding and spacing between image.

With rTexPacker you can easely package sprites and export atlas information in multiple formats (XML, JSON, CODE...).

• Package sprites and font glyphs into an atlas

• Configure packing algorithms and heuristics

• Setup sprites spacing, padding and alpha-trimming

• Font generation options: Size, SDF fonts, fixed font height

• Import custom unicode charset from UTF-8 file

• Unicode charset duplicates removed automatically

• Edit sprites origin visually, exported with the atlas

• Atlas visualization options: Zoom, Pan, Background, Fill

• Multiple UI styles available, selectable from main toolbar

• Load/Save portable self-contained .rtp file, containing all sprites

• Load sprites from multiple image formats: .png, .qoi, .tga, .jpg

• Load sprites from font files: .ttf, .otf

• Export atlas descriptor as: text (.rtpa), binary (.rtpb), .json, .xml and code (.h)

• Export atlas image as: .png, .qoi, .dds and .raw

• Export atlas descriptor as binary PNG chunk: rTPb

• Multiple usage examples provided to load: .rtpa, .rtpb, PNG chunk rTPbp and code .h.

• Maximum atlas size up to 16384x16384 pixels

• Command-line support for batch sprites packing

• Completely portable (single-file, no-dependencies)

rTexPacker is handmade software, it has been meticulously developed using the C programming language, with great attention put on every line of code written. This approach usually results in highly optimized and efficient code, but it is also more time-consuming and require a higher level of technical skills. The result is great performance and small memory footprint.
