I've been trying to display a map with a single layer - a raster image -
but so far I'm stumped. I'm using a tiff image with a world file.
Here's what I've tried so far:
(1) Verified that MS was compiled with tiff support.
(2) Made sure the tiff image is indexed, not RGB
(3) Fiddled with the extents in the world file
(4) Made sure that the image path is specified correctly
(5) Tried changing the "STATUS ON" statement in the layer to "STATUS
DEFAULT"
Still, all I get is a blank image (just the background color) with no
map. I would greatly appreciate any advice folks can give.
Here is the text of the four relevant files, cal03_init.html,
cal03.html, cal03.map map and cal03.wld:
cal03_init.html:
