SwiftGL is libraries for graphics programming that's 100% Swift.
To use, include dependency in your Package.swift:
let package = Package(
dependencies: [
.Package(url: "https://github.com/SwiftGL/Image.git", majorVersion: 2)
]
)Then import SGLImage in your swift file.
Currently, BMP, PNG and GIF importing are working. This is all 100% Swift, there are no bindings to any external code at all.
import SwiftGLres
let loader = SGLImageLoader(fromFile: "/path/to/file.bmp")
assert(loader.error == nil, loader.error!)
// You can inspect info like loader.decoder!.channels here.
// Images are automatically converted to fit any SGLImageType provided.
let image = SGLImageRGB<UInt8>(loader)
assert(loader.error == nil, loader.error!)
Loading into floats will make the color channels linear by applying a gamma of 2.2. You can change the gamma in the loader. If the image specifies a gamma, it will set the loader to match.
There's also an inflate (gzip) algorithm you can use.
