NAME

composite - composite images together.

SYNOPSIS

composite [__ ''options'' __...? image composite [__ ''mask'' __? composited

DESCRIPTION

composite composite images to create new images.

The optional mask can be used to provide matte information for composite when it has none or if you want a different mask. A mask image is typically grayscale and the same size as composite. If the image is not grayscale, it is converted to grayscale and the resulting intensities are used as matte information.

If composited already exists, you will be prompted as to whether it should be overwritten.

EXAMPLES

To composite an image of a cockatoo with a perch, use:

composite cockatoo.miff perch.ras composite.miff

To compute the difference between images in a series, use:

composite -compose difference series.1 series.2 difference.miff

To composite an image of a cockatoo with a perch starting at location (100,150), use:

composite -geometry +100+150 cockatoo.miff perch.ras composite.miff

To tile a logo across your image of a cockatoo, use

convert +shade 30x60 cockatoo.miff mask.miff composite

• compose bumpmap -tile logo.png cockatoo.miff mask.miff

composite.miff

To composite a red, green, and blue color plane into a single composite image, try

composite -compose !CopyGreen? red.png green.png red-green.png composite -compose !CopyBlue? red-green.png blue.png composite.png

OPTIONS

Options are processed in command line order. Any option you specify on the command line remains in effect only for the image that follows. All options are reset to their default values after each image is read.
