Images
topLevelWindowSetIconFromFile :: TopLevelWindow a -> FilePath -> IO () Source #
Set the icon of a frame.
Imagelist
imageListAddIconsFromFiles :: ImageList a -> Size -> [FilePath] -> IO () Source #
Initialize an image list with icons from files. Use a sizeNull to
use the native size of the loaded icons.
imageListAddIconFromFile :: ImageList a -> Size -> FilePath -> IO () Source #
Add an icon from a file to an imagelist.
Icons
withIconFromFile :: FilePath -> Size -> (Icon () -> IO a) -> IO a Source #
Load an icon (see iconCreateFromFile) and automatically delete it
after use.
Cursors
withCursorFromFile :: FilePath -> (Cursor () -> IO a) -> IO a Source #
Load a cursor (see cursorCreateFromFile) and automatically delete it
after use.
cursorCreateFromFile :: String -> IO (Cursor ()) Source #
Load a cursor from an icon file (ico,xbm,xpm,gif).
For a reason, this function is incompatible with iconCreateFromFile.
Bitmaps
withBitmapFromFile :: FilePath -> (Bitmap () -> IO a) -> IO a Source #
Load a bitmap (see bitmapCreateFromFile) and automatically delete it
after use.
bitmapCreateFromFile :: FilePath -> IO (Bitmap ()) Source #
Load a bitmap from an image file (gif, jpg, png, etc.)
Helpers
imageTypeFromExtension :: String -> BitFlag Source #
Get an image type from a file extension.
imageTypeFromFileName :: String -> BitFlag Source #
Get an image type from a file name.
Direct image manipulation
imageCreateFromPixels :: Size -> [Color] -> IO (Image ()) Source #
Create an image from a list of pixels.
imageGetPixelArray :: IArray a Color => Image b -> IO (a Point Color) Source #
Get the pixels of an image as an array
imageCreateFromPixelArray :: IArray a Color => a Point Color -> IO (Image ()) Source #
Create an image from a pixel array
withImageData :: Image a -> (Ptr () -> IO b) -> IO b Source #
Do something with the pixels of an image
Pixel buffer
imageCreateFromPixelBuffer :: PixelBuffer -> IO (Image ()) Source #
Create an image from a pixel buffer. Note: the image will delete the pixelbuffer.
imageGetPixelBuffer :: Image a -> IO PixelBuffer Source #
Deprecated: Use withPixelBuffer instead
Get the pixel buffer of an image.
Note: use withPixelBuffer instead
withPixelBuffer :: Image a -> (PixelBuffer -> IO b) -> IO b Source #
data PixelBuffer Source #
An abstract pixel buffer (= array of RGB values)
pixelBufferCreate :: Size -> IO PixelBuffer Source #
Create a pixel buffer. (To be deleted with pixelBufferDelete).
pixelBufferDelete :: PixelBuffer -> IO () Source #
Delete a pixel buffer.
pixelBufferInit :: PixelBuffer -> Color -> IO () Source #
Initialize the pixel buffer with a grey color. The second argument specifies the greyness as a number between 0.0 (black) and 1.0 (white).
pixelBufferSetPixel :: PixelBuffer -> Point -> Color -> IO () Source #
Set the color of a pixel.
pixelBufferGetPixel :: PixelBuffer -> Point -> IO Color Source #
Get the color of a pixel
pixelBufferSetPixels :: PixelBuffer -> [Color] -> IO () Source #
Set all the pixels of a pixel buffer.
pixelBufferGetPixels :: PixelBuffer -> IO [Color] Source #
Get all the pixels of a pixel buffer as a single list.
pixelBufferGetSize :: PixelBuffer -> Size Source #
The size of a pixel buffer
