number | start location on the x axis of the output pixel buffer |
yStart |
number | start location on the y axis of the output pixel buffer |
xStop |
nubmer | location to stop at on the x axis |
yStop |
number | location to stop at on the y axis |
fn |
function | handle to call with each iterated address |
_eachCell(xStart, yStart, xStop, yStop, xStep, yStep, fn)
Iterate over cells of pixels and call a function with a function to iterate over pixel addresses.
Parameters:
| Name | Type | Description |
