Gontage

Create spritesheets from multiple folders of sprites/images up to ~48x+ faster than ImageMagicks montage command.

Install

go install github.com/LeeWannacott/gontage@latest

Usage:

gontage -h

Example:

Benchmarking:

Multiple folders containing sprites -mf:

• gontage was up to ~48x faster than montage at creating multiple spritesheets (tested on a 12 core AMD 5900x)

Single folder -f:

• gontage was ~3.5x faster in this instance tested on a 12 core AMD 5900x

• ~2.5x faster on a 2 core 4 thread i5-4210U Skylake CPU.

At around the same level of compression:

Other Info:

• Using an appImage for ImageMagick adds around 0.8seconds to startup time when running montage...
• Building an equivalent in NodeJS took around ~700ms (800ms with Bun) for one folder 7x slower than Gontage (~90ms) and 2x slower than Montage (~350ms).
