WARNING: PLEASE READ ALL DOCS AND BACKUP YOUR IMAGES BEFORE USING THIS APP!


This DOS DPMI program is a utility for frame rendering software (such as POV-ray or Lightwave) that output type 2 uncompressed Targa files (TGA). It takes the image in IMPRINT.TGA and masks it on to all other TGA files in the same folder that are the same format and width/height as itself.

The primary use of the app is placing copyright notices and logos on your animation frames before conversion to MPEG, MOV, AVI, etc.

The normal imprint mode is MASKED. Upon invoking imprint all appropriate TGA files in the current directory have the imprint.tga image masked onto them -- that is, all non black (RGB 0,0,0) pixels overwrite your image.

For a more advanced and useful technique you can use ALPHA BLENDING mode, invoked by the -a parameter. This makes use of the ALPHA.TGA to determine how the IMPRINT.TGA is alpha-blending onto your frame images. ALPHA.TGA has three channels (RGB). A colour of 0 (in any channel) means no blending -- fully transparent. A 255 means 100% complete overwrite.

Which is better? MASKED or ALPHA BLENDING? Depends on how complicated your IMPRINT.TGA image is. Experiment. If your IMPRINT.TGA has anti-aliasing you'll need to be careful about your background colours.


Syntax is:
imprint [-?] [-a] [-aa] [-t] [-fn]


-?
	Help

-a
	Use three channel (RGB) alpha blending

-aa
	Antialiasing. (NOT IMPLIMENTED)

-t
	Texel n-width/height mapping. (NOT IMPLIMENTED)

-fn
	Filename/timedate stamping. (NOT IMPLIMENTED)
