PreserveAlpha

- if set to “true”, preserves the alpha channel of the target image as the

alpha channel of the resulting image. The default is false.

Blend

- speciﬁes the type of blending used to combine the drawn object with the images.

Blend options are: “Normal”, “Darken”, “Lighten”, “Hue”, “Saturation”, “Color”,
“Luminosity”, “Multiply”, “Screen”, “Dissolve”, “Overlay,” “HardLight”, “SoftLight”,
“Difference”, “Exclusion”, “Dodge”, “ColorBurn”, “Under”, “Colorize” (causes only the
hue component of the source to be stamped down on the image), and “Prenormal”.

NOTE:

“Burn” has been deprecated. “ColorBurn” results in the same blend.

Width

- speciﬁes the thickness (in pixels) of the line that describes the rectangle. The

default is 1.

NOTE:

If the Fill parameter is set to true, Width is ignored.

Smooth

- if set to “true”, makes the edges of the rectangle smooth, preventing a pixellated

effect. The default is false.

Fill

- ﬁlls in the rectangle with the color speciﬁed by the Color or Index parameter. The

default is false.

Example

var image = new Media();

image.load(name @ "family2.jpg");

image.rectangle(x @ 45, y @ 55, xs @ 283, ys @ 157, width @ 3);

image.save(type @ "jpeg");

r e d u c e ( )

MediaRich also supports Adobe Color Table (.act) ﬁles.
