- _c_y_u_v_2_p_p_m is a conversion program between component yuv
- files and the ppm file format. The chrominances of the
- input are decimated by a factor of 2 in both the horizon-
- tal and vertial dimensions.
-
-

- --iiww is the image width in terms of the luminance compo-
- nent (Y).
-
- --iihh is the image height in terms of the luminance com-
- ponent (Y).
-
- --CCCCIIRR660011
- specifies that the CCIR601 YCbCr colorspace is to
- be used instead of the JFIF colorspace.
-
- --zz denotes the component file suffixes in sequential
- order. For example
- --zz ..yy..ccllrr --zz ..uu..ccllrr --zz ..vv..ccllrr indicates that the
- luminance and the two chrominance files end with a
- suffix of ..yy..ccllrr,, ..uu..ccllrr,, and ..vv..ccllrr,, in that
- order. If unspecified, the suffixes default to ..YY,,
- UU,, and ..VV..

- To convert a triple set of raw raster scan YCbCr (also
- known as digital YUV) files with dimension 352x240 Y,
- 176x120 U,V, with labels, hheelllloo00..YY hheelllloo00..UU hheelllloo00..VV,, to
- the file oouutt..ppppmm type
-
- ccyyuuvv22ppppmm hheelllloo00 oouutt..ppppmm
-
- There are a variety of ways to convert the PPM file to
- other formats; see Jef Poskanzer's PBMPLUS library.
