composite.im6 命令

常用示例

说明

composite.im6 is the ImageMagick version 6 command for combining images through compositing operations. It is functionally identical to composite but explicitly references the ImageMagick 6 installation, useful on systems where both ImageMagick 6 and 7 are installed. The tool overlays one image on another using various blending modes and positioning options. It supports mask-based compositing, watermarking, and dozens of composition operators matching professional image editing capabilities. On most systems, this command exists as a versioned alternative to ensure compatibility with scripts written for ImageMagick 6 when ImageMagick 7 is also present. The im6 suffix indicates the legacy API version.
