Imageman
Rudimentary image manipulation framework.
Some things may or may not work correctly.
Check examples directory for short demonstration.
Why
To have some boilerplate for recreational programming with images.
Manipulate. Images.
Projects using imageman
diffimg - image diffing tool and library.
blurhash - blurhash algorith implementation.
Installation
nimble install imageman
Backends
libjpeg(-turbo)
- Activated with
imagemanLibjpegflag. Enabled by default. - SIMD accelerated JPEG encoder/decoder.
- Dynamically linked. Requires dll/so/dylib at runtime.
libpng
- Activated with
imagemanLibpngflag. Enabled by default. - Fast PNG encoder/decoder (outperforms
stb_image). - Dynamically linked. Requires dll/so/dylib of itself and zlib at runtime.
stb_image
- Activated with
imagemanStbflag. By default only enabled if libjpeg and libpng are disabled. - Supports reading and writing PNG, JPEG, BMP and TGA images but with limited control.
- Header only - compiled in.
