gif
clamp(value: Float, a: Float, b: Float): Float

Clamp a value between a and b and return the clamped version

gif
print(): Void

Allows a custom print handler for error messages. Defaults to Sys.println on sys targets, and trace otherwise.

new(_frame_width: Int, _frame_height: Int, _framerate: Float, ?_repeat: Int = GifRepeat.Infinite, ?_quality: Int = 10): Void

Construct a gif encoder with options:

frame width/height: Default is 0, required

framerate: This is used if an added frame has a delay that is negative.

repeat: Default is 0 (no repeat); -1 means play indefinitely. Use GifRepeat for clarity

quality: Sets quality of color quantization (conversion of images to the maximum 256 colors allowed by the GIF specification). Lower values (minimum = 1) produce better colors, but slow processing significantly. Higher values will speed up the quantization pass at the cost of lower image quality (maximum = 100).

Name Type Default
_frame_width Int
_frame_height Int
_framerate Float
_repeat Int GifRepeat.Infinite
_quality Int 10
