Arguments
| :: (Ord r, Floating r) | |
| => Coordinates r | coordinates |
| -> Int | max iterations |
| -> UArray (Int, Int) Bool | image |
Render an image with the Simple algorithm. The iteration count is
doubled until the image is good enough, or the fixed maximum iteration
count is reached.
putStr . unicode $ simpleImage (coordinates 100 100 ((-1.861):+0) (0.001)) 1000000000
Arguments
| :: (Ord r, Real r, Floating r) | |
| => Coordinates r | coordinates |
| -> Int | max iterations |
| -> UArray (Int, Int, Channel) Float | image |
Render an image with the DistanceEstimate algorithm. The iteration count is
doubled until the image is good enough, or the fixed maximum iteration
count is reached. The output values are converted to Float.
putStr . unicode . border $ complexImage (coordinates 100 100 ((-1.861):+0) (0.001)) 1000000000
Arguments
| :: (Ord r, Floating r) | |
| => STRef s Int | escapees |
| -> a | output array |
| -> Int | max iterations |
| -> Int | iterations |
| -> Bool | prior escapees |
| -> Int | iterations this phase |
| -> [Iterate u r] | iterates |
| -> (Output u r -> ST s ()) | output callback |
| -> ST s a | output array as given |
Image rendering loop.
Arguments
| :: (Ord r, Floating r) | |
| => Int | width |
| -> Int | height |
| -> Complex r | center |
| -> r | size |
| -> Coordinates r |
The parameter plane coordinates for an image, with bounds.
Convert a bit array to ascii graphics.

Channels in an image.
Constructors
