|stb-image-0.2: A wrapper around Sean Barrett's JPEG/PNG decoder||Contents||Index|
|A wrapper around stb_image, Sean Barrett's public domain JPEG/PNG decoder.
The original can be found at http://nothings.org/stb_image.c.
The version of stb_image used here is stbi-1.18.
The current list of (partially) supported formats is JPEG, PNG, TGA, BMP, PSD.
Please note that the library is not (fully) thread-safe!
|type Image = Bitmap Word8|
|decodeImage :: ByteString -> IO (Either String Image)|
Decodes an image from a compressed format stored in a strict ByteString.
Supported formats (see stb_image.c for details!):
- JPEG baseline (no JPEG progressive, no oddball channel decimations)
- PNG 8-bit only (8 bit per component, that is)
- BMP non-1bpp, non-RLE
- TGA (not sure what subset, if a subset)
- PSD (composite view only, no extra channels)
If the operation fails, we return an error message.
|decodeImage' :: Int -> ByteString -> IO (Either String Image)|
|Decodes an image, with the number of components per pixel forced by the user.
|loadImage :: FilePath -> IO (Either String Image)|
|Loads an image from a file. Catches IO exceptions and converts them to an error message.
|loadImage' :: FilePath -> Int -> IO (Either String Image)|
|Force the number of components in the image.
