常用示例
Compare two GIF files
gifdiff [file1.gif] [file2.gif]
Brief mode
gifdiff -q [file1.gif] [file2.gif]
Ignore frame-redraw differences
gifdiff -w [file1.gif] [file2.gif]
Use in a shell script
gifdiff -q [file1.gif] [file2.gif] && echo "identical"
说明
gifdiff compares two GIF image files and determines whether they display identically when rendered. Unlike a byte-wise comparison, it accounts for semantically irrelevant encoding differences (for example, different frame disposal methods that produce the same visible output). gifdiff is part of the gifsicle toolkit and is primarily useful for regression testing of GIF generators and for confirming that two differently encoded files produce the same animation.
参数
- -q, --brief
- Produce no output; only return an exit status (0 if images display identically, 1 otherwise).
- -w, --ignore-redraw
- Ignore differences that only affect how frames are redrawn. Two animations that render identically but encode redraws differently are still treated as equal.
- -h, --help
- Print usage information and exit.
- -v, --version
- Print the gifdiff version and exit.
