Images
frameSetIconFromFile :: Frame a -> FilePath -> IO ()
Set the icon of a frame.
Imagelist
imageListAddIconsFromFiles :: ImageList a -> Size -> [FilePath] -> IO ()
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 ()
Add an icon from a file to an imagelist.
Icons
withIconFromFile :: FilePath -> Size -> (Icon () -> IO a) -> IO a
Load an icon (see iconCreateFromFile) and automatically delete it after use.
iconCreateFromFile :: FilePath -> Size -> IO (Icon ())
Load an icon from an icon file (ico,xbm,xpm,gif). The Size argument gives the desired size but can be sizeNull to retrieve the image in its natural size.
iconGetSize :: Icon a -> IO Size
Get the size of an icon.
Cursors
withCursorFromFile :: FilePath -> (Cursor () -> IO a) -> IO a
Load an cursor (see cursorCreateFromFile) and automatically delete it after use.
cursorCreateFromFile :: String -> IO (Cursor ())
Load an cursor from an icon file (ico,xbm,xpm,gif). For a reason, this function is incomatible with iconCreateFromFile.
Bitmaps
withBitmapFromFile :: FilePath -> (Bitmap () -> IO a) -> IO a
Load a bitmap (see bitmapCreateFromFile) and automatically delete it after use.
bitmapCreateFromFile :: FilePath -> IO (Bitmap ())
Load a bitmap from an image file (gif, jpg, png, etc.)
bitmapGetSize :: Bitmap a -> IO Size
The size of a bitmap.
bitmapSetSize :: Bitmap a -> Size -> IO ()
Set the size of a bitmap.
Helpers
imageTypeFromExtension :: String -> BitFlag
Get an image type from a file extension.
imageTypeFromFileName :: String -> BitFlag
Get an image type from a file name.
Direct image manipulation
imageGetPixels :: Image a -> IO [Color]
Get the pixels of an image.
imageCreateFromPixels :: Size -> [Color] -> IO (Image ())
Create an image from a list of pixels.
imageGetPixelArray :: Image a -> IO (Array Point Color)
Get the pixels of an image as an array
imageCreateFromPixelArray :: Array Point Color -> IO (Image ())
Create an image from a pixel array
imageGetSize :: Image a -> IO Size
Get the size of an image
withImageData :: Image a -> (Ptr () -> IO b) -> IO b
Do something with the pixels of an image
Pixel buffer
imageCreateFromPixelBuffer :: PixelBuffer -> IO (Image ())
Create an image from a pixel buffer. Note: the image will delete the pixelbuffer.
imageGetPixelBuffer :: Image a -> IO PixelBuffer
Get the pixel buffer of an image. Note: use withPixelBuffer instead
withPixelBuffer :: Image a -> (PixelBuffer -> IO b) -> IO b
data PixelBuffer
An abstract pixel buffer (= array of RGB values)
pixelBufferCreate :: Size -> IO PixelBuffer
Create a pixel buffer. (To be deleted with pixelBufferDelete).
pixelBufferDelete :: PixelBuffer -> IO ()
Delete a pixel buffer.
pixelBufferInit :: PixelBuffer -> Color -> IO ()
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 ()
Set the color of a pixel.
pixelBufferGetPixel :: PixelBuffer -> Point -> IO Color
Get the color of a pixel
pixelBufferSetPixels :: PixelBuffer -> [Color] -> IO ()
Set all the pixels of a pixel buffer.
pixelBufferGetPixels :: PixelBuffer -> IO [Color]
Get all the pixels of a pixel buffer as a single list.
pixelBufferGetSize :: PixelBuffer -> Size
The size of a pixel buffer
