Thanks - I have it working using depth 8. File sizes are the expected 2,073,600.
I believe I had some other system related issues - nfs/overlays - which had inhibited the correct file from being used.

Re: Magick++ how to read bitmap 256 color, convert to RGBA
I'll reiterate:
1) Not using command line
2) Problem to be solved is reading in bitmaps, i.e. *.bmp
3) Current code is completely basic - image read in filename.* where * is jpg. png, etc, then write filename.rgba.
4) Code works for jpg. png, tiff, and 24 BPP bitmap files
Problem was with bitmap ...

output is *.rgba. The 256 bitmap actually looks correct, the 16 is rendered at quarter size - twice - in the upper half of the expected area, the bottom half is some noise pattern. The mono bitmap renders as a thin band across the top of the expected area.

Magick++ how to read bitmap 256 color, convert to RGBA
Hi all,
[ somewhat new to IM ]
I need to read in various bitmaps ( 256 color, 16 , mono ) and convert to RGBA programmatically. I have code which works for converting jpeg, png, tiff, and 24 bit per pixel bitmaps; all that code does is pass a filename to image constructor then write out RGBA ...
