+
+- Returned image data is 8-bit except PNG can also return 16-bit.
+- Image data can be converted to Y, YA, RGB or RGBA.
+- There's a `@nogc` remake: [imagefmt](https://github.com/tjhann/imagefmt)
+
+**Decoders:**
+- PNG. 8-bit and 16-bit interlaced and paletted (+`tRNS` chunk)
+- TGA. 8-bit non-paletted
+- BMP. 8-bit uncompressed
+- JPEG. baseline
+
+**Encoders:**
+- PNG. 8-bit non-paletted non-interlaced
+- TGA. 8-bit non-paletted rle-compressed
+- BMP. 8-bit uncompressed
