HamLab Version 1.1
(c) Copyright 1990, 1991 J. Edward Hanway
FILE TYPES SUPPORTED
GIF (Graphics Interchange Format)
GIF versions GIF87a and GIF89a are both supported.
Non-interlaced GIF files require much less memory to convert than
interlaced GIF files. NOTE: This "interlace" has nothing to do with
the Amiga display. An "interlaced" GIF file stores the lines of the
image in scrambled order, rather than top-to-bottom, so that, in theory,
you can see the overall picture sooner while it is being displayed.
Most GIF files are not interlaced.
TIFF (Tag Image File Format)
Supports black&white or gray scale images with 1, 4, or 8 bit planes.
Supports RGB color images with 3, 12, or 24 bit planes.
Images must either be uncompressed or use PackBits compression (type
32773).
SPECTRUM 512
Normal, compressed (.SPC) files supported. Uncompressed (.SPU) and .SPS
files are not supported.
PBMPLUS
Black&white (PBM), gray scale (PGM), and color (PPM) files are all
supported. Both ASCII and RAW (binary) formats are supported.
MTV
The RAYSHADE ray tracer by Craig E. Kolb can also write images in this
format.
QRT, DKBTrace
Although both the QRT and DKBTrace ray tracers use the same file format,
QRT uses only 21 bits of information per pixel while DKBTrace uses 24
bits. With default settings, DKBTrace pictures will look correct, while
QRT pictures will be too dark, but this can be compensated by increasing
the brightness. (The easiest way to do this is to load the color
control settings from the "QRT_color_response" file.)
SUN RASTERFILES
Black&white, 8-bit mapped color, and 24-bit color images are supported.
Both uncompressed and run-length compressed raster files are supported.
