StbImageBeef is Beef port of the stb_image.h, which is C library to load images in JPG, PNG, BMP, TGA, PSD and GIF formats.
It is important to note, that this project is port(not wrapper). Entire C code had been ported to Beef.
FileStream fs = scope FileStream();
fs.Open(path, .Open, .Read);
ImageResult image = ImageResult.FromStream(fs, ColorComponents.RedGreenBlueAlpha);ImageInfo class could be used to obtain an image info like this:
ImageInfo? info = ImageInfo.FromStream(imageStream);It'll return null if the image type isnt supported, otherwise it'll return the image info(width, height, color components, etc).
There is special app to measure reliability & performance of StbImageBeef in comparison to the original stb_image.h: https://github.com/StbBeef/StbImageBeef/tree/master/samples/StbImageBeef.Testing
It goes through every image file in the specified folder and tries to load it 10 times with StbImageBeef, then 10 times with native wrapper over the original stb_image.h(Stb.Native). Then it compares whether the results are byte-wise similar and also calculates loading times. Also it sums up and reports loading times for each method.
I've used it over following set of images: https://github.com/StbSharp/TestImages
The byte-wise comprarison results are similar for StbImageBeef and Stb.Native.
And performance comparison results are(times are total loading times):
