常用示例
Combine YUV component files into a PPM image
yuvsplittoppm [base] [width] [height] > [output.ppm]
Combine using CCIR 601 (MPEG) colour scaling
yuvsplittoppm -ccir601 [base] [width] [height] > [output.ppm]
说明
yuvsplittoppm reads three raw files containing the Y, U, and V colour components and produces a PPM image on standard output. The filenames are derived from _basename_ by appending `.Y`, `.U`, and `.V`. Because the files are raw with no header, the image dimensions must be given on the command line. It is the inverse of ppmtoyuvsplit(1) and is part of the Netpbm toolkit.
参数
- -ccir601
- Interpret YUV values using the CCIR 601 (MPEG) range rather than the default JFIF (JPEG) range.
