ppmto3DO

ppmto3DO

Converts a PPM file to 3DO format.

Synopsis

ppmto3DO [flags] <ppmimagefile> < 3DOimagefile>

Description

Converts a file in portable pixmap (PPM) format to 3DO image format.

Options

-b
pixels of the output image are in 5541 format, with the low bit of the blue component used as a corner weight
-c
output a 16-bit-per-pixel, non-LR-form image suitable for processing by makecel
-d
write to the output file a dynamic VDL containing a CLUT for each display line; default is no CLUT written
-f
write to the output file a fixed VDL containing a single CLUT for the image; default is no CLUT written
-t N
specify a color in the input image to be translated to transparent (zero) in the output image; N is a hexadecimal number representing a 16-bit, 555-RGB color value
-v
print total number of colors in output image
-e N
place entries in the generated CLUT beginning at index N; default is 0; the values supplied to -ce and -me must add to be 32 or less.
-m N
use at most N entries in the generated CLUT; default is 32
The following options specify how the colors entered in the generated CLUT are selected from the colors found in the input image (or a line of the input image, when -d is in effect):

-s0
entries evenly distributed across the color space; default when -d is not in effect
-s1
entries that are the most popular color values
-s2
entries that represent approximately equal regions of the color space by population
-s3
entries that represent subdivisions of longest intervals between color values
-s4
entries that represent subdivisions of intervals containing the largest numbers of colors (population)
-s5
entries that represent subdivisions of longest intervals based on color value weighted by population; default when -d is ineffect
