Texturize effect
The Texturize effect gives a layer the appearance of having the texture of another layer. For example, you could make
the image of a tree appear as if it had the texture of bricks, and control the depth of the texture and the apparent light
source. At Best quality, the texture layer is positioned and scaled with subpixel precision.
This effect works with 8-bpc color.

How the texture layer is applied to the effect layer:

• Stretches the texture to the dimensions of the effect layer.

Threshold effect
The Threshold effect converts grayscale or color images to high-contrast, black-and-white images. Specify a certain
level as a threshold; all pixels lighter than the threshold convert to white and all pixels darker convert to black.
This effect works with 8-bpc and 16-bpc color.
Effect applied with threshold settings of 44 (left), 70 (center), and 200 (right)
