For the "gif" format, the image_map feature "transmit/filter all 1.0"
seems to work as expected. But for "png", "tga", and "bmp" formats such
is not the case. Is there a bug in the "transmit/filter" feature for
"png", "tga", and "bmp" or is there something I'm missing.
I'd really prefer to use a format other than "gif" that supports a
greater number of colors.

It is not a bug. The filter and transmit all only works on images that have
an 8 bit 256 color palette. I think you can save your .bmp, tga or whatever
in 8 bit 256 colors and use those image formats but you lose the color depth
you are looking for.

Oh well, thanks Ken.

.png files can use an alpha channel as well, so you can control the
transparency with a graphic editor that doesn't relate to the main image.
