initialize :: Size -> IO State Source #
If you want to write your own functions, call this function before pictureToImage*
Arguments
| :: Size | (width, height) in pixels - as in Gloss.Display |
| -> Color | Background color |
| -> State | Result of |
| -> Picture | |
| -> IO (Image PixelRGB8, Ptr (PixelBaseComponent PixelRGB8)) | image and a pointer to memory |
convert a gloss Picture into an Image.
The pointer should be freed after the image is no longer needed in memory
Use 'free ptr' to free the memory.

| -> State | Result of |
| -> Picture | |
| -> IO (Image PixelRGBA8, Ptr (PixelBaseComponent PixelRGBA8)) | image and a pointer to memory |
convert a gloss Picture into an Image.

exportPictureToFormat Source #
Arguments
| :: (FilePath -> Image PixelRGBA8 -> IO ()) | function that saves an intermediate representation to a format. Written with writeXY from Codec.Picture in mind |
| -> Size | (width, heigth) in pixels - as in Gloss.Display |
| -> Color | Background color |
| -> FilePath | |
| -> Picture | |
| -> IO () |
Save a gloss Picture to a file.
exportPicturesToFormat Source #
Arguments
| :: (FilePath -> Image PixelRGBA8 -> IO ()) | function that saves an intermediate representation to a format. Written with writeXY from Codec.Picture in mind |
| -> Size | (width, height) in pixels - as in Gloss.Display |
| -> Color | background color |
| -> FilePath | must contain "%d", will be replaced by frame number |
| -> Animation | function that maps from point in time to Picture. analog to Gloss.Animation |
| -> [Float] | list of points in time at which to evaluate the animation |
| -> IO () |
Save a series of gloss Picture to files of spcified format.
