(O): Gabor Patch

This type generates a Gabor patch.

Parameter: size, envelope, frequ, phase, bcolor, fcolor1, fcolor2 [, orient [, edge]]

size width and height of the Gabor patch in mm

envelope shape of patch (Gaussian, linear, cos, hann, hamming, circle)

frequ cycles in mm

phase start poin in cycle (0-1).

bcolor background color

fcolor1 foreground color for high cycle

fcolor2 foreground color for low cycle

orientaation Rotation angle (0°-360°) in degrees (default 0)

edge Edge of patch in mm for Gaussian envelope (default 1/8 size)

To make the Gabor patch appear seamlessly evolving out of the background, match the background color of the patch with the background color of the screen and set the edge to at least 1/8 of the size of the patch to avoid visible cut off of the Gabor pattern.
