Gui blocks.png



gui_blocks.png was a texture atlas found inside minecraft.apk that was used to load the inventory icons for the game's blocks and items.

Format
gui_blocks.png is a fixed-width 512×512-pixel file that is split into different 48×48 and 16×16 squares which correspond to the texture of each block and item icon in the inventory.

Usage
gui_blocks.png was used to generate inventory icons for blocks and items with a single image instead of a render to increase performance. If a block or item was not defined in this file, its inventory icon would instead get generated with terrain.png or items.png and have a red background.
