Synopsis |
|
|
|
|
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
