C # parse the SUM grating file image (RAS file)

Usage,

 

ImageRas _ Ras = new ImageRas (@ "D: empest. ras ");
PictureBox1.Image = _ Ras. Image;

 

_ Ras. SaveRas (@ "d: empOK. ras ");

 

I only implemented the 24-bit color and 8-bit color structure, which is too simple. Only the file header and data area are supported. The 8-bit color table has some special features.

 

First, the red table, the green table, and the blue table are usually RGB and RGB. In this case, the RRRR... GGG... B ....

 

I don't know what to think.

 

There is little time to do these things when there are too many projects. The next target is the IFF file.
