/** Analyze bitmap image file, apply the following tests:
- If the image is RGB or CMYK, if R=G=B or C=M=Y for each pixel,
writing gray output is sufficient.
- If the image contains an alpha channel and alpha data indicates
full opacity for all pixels, we can ignore the alpha channel.
- If we can reduce the number of bits per component (bits per sample)
for all samples of all pixels without quality loss, do so.
@param pcs Address of color space variable (in/out).
@param pbd Address of bit depth (in/out).
@param bif Bitmap image file.
