Short: Replacement for CBM's macpaint.datatype
Author: TetiSoft@apg.lahn.de (Detlef Wuerkner)
Uploader: TetiSoft@apg.lahn.de (Detlef Wuerkner)
Version: 43.1
Type: util/dtype
macpaint.datatype Version 43.1 (10-Jul-97)
It's a datatype for MacPaint picture format, based on the sources
of Andreas R. Kleinert's samplePNM.datatype. MacPaint pictures are
black & white, 720 * 576 pixels.
Written to replace macpaint.datatype 42.1 from CBM
(Aminet util/dtype/picdt_42_1.lha). I found two bugs in it:
1) The descriptor hook-function didn't recognize all MacPaint pictures,
but declared a large number of other files as MacPaint pics. The
new descriptor from Erik Engdahl (Aminet util/dtype/MacPict2_dtc.lha)
was better, but recognized also Compugraphic fonts as MacPaint.
My descriptor checks deeper: It tests if the data is packed with
the PackBits procedure.
2) With SetPatch 43.6 installed, the old macpaint.datatype produces
completely black pictures (at least on my system). With
SetPatch 40.16 it worked. My version doesn't have this problem.
