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");
reduce()
Applies a specified or generated color palette to the image. By default, this function
generates an optimal palette of 256 colors.
NOTE: MediaRich also supports Adobe Color Table (.act) files.
