Process

Command Syntax Description

Blur

Blur(srcImage,

destImage,

radius, aspect)

Performs a blur operation on

the source image buffer and

places the result in the

destination image buffer.

“Radius” speciﬁes the radius of

the blurred area.

BlurChannel

BlurChannel(srcImage,

destImage,

radius, doAlpha,

doRed, doGreen,

doBlue, aspect)

Performs a blur operation on

the speciﬁed channels of the

source image buffer and places

the result in the destination

image buffer. Any of the four

channels can be omitted.

“Radius” speciﬁes the radius of

the blurred area. The

doChannel values are Boolean

numbers, either known

numbers or variables.

Diffuse

Diffuse(srcImage,

destImage,

repeatEdges,

hMin, hMax, vMin,

vMax)

Each pixel in the destination

image buffer is ﬁlled with a pixel

from the source image buffer,

which is offset spatially by a

random number. The range for

this random number is deﬁned

by the values assigned to

“hmin” and “hmax” on the

horizontal axis, and “vmin” and

“vmax” on the vertical axis.

“RepeatEdges” is a Boolean

operation that determines

whether pixels that would be

beyond the bounds of the

source image are ﬁlled with

copies of the nearest edge pixel,

or with transparent black pixels.
