Scaling
:: (Pixel a, Bounded (PixelBaseComponent a), Integral (PixelBaseComponent a)) | |
=> Int | Desired width |
-> Int | Desired height |
-> Image a | Original image |
-> Image a | Scaled image |
Scale an image using bi-linear interpolation.
Cropping
:: Pixel a | |
=> Int | Index (X axis) of first pixel to include |
-> Int | Index (Y axis) of first pixel to include |
-> Int | Width of resulting image |
-> Int | Height of resulting image |
-> Image a | Original image |
-> Image a | Cropped image |
Crop a given image. If supplied coordinates are greater than size of original image, image boundaries are used instead.
Rotation
rotate180 :: Pixel a => Image a -> Image a Source #
Rotate an image by 180°, i.e flip both vertically and horizontally.
