Changing a grayscaled TIF to Color

[Catchen]

Hi,
I have been using ImageMagick for about a week and are totaly hooked by this great application.
I've done a few cool things with it and searching to learn more. Well now to the problem.

I have a bunch of TIF files. These files are drawings Black & White ones.
If I try to draw lets say a rectangle in color with IM it the rectangle becomes grey.
convert test.tif -fill red -draw "rectangle 100x100 400x400" redrect.tif

I started to search for icc profiles, colorspace etc but couldnt get these files to open up for color.

Im a total newbie and I understand that some would say RTFM but after reading until my eyes got crazy and still not finding a solution I ask you guys.
Maby im dumb or even blind but I would love to get some help with this..

the identify -verbose tells

try changing the image type from bilevel to truecolor

convert test.tif -type truecolor -fill red -draw "rectangle 100x100 400x400" redrect.tif

see -type http://www.imagemagick.org/script/comma ... s.php#type

Does that work?

alternately, try setting the -channel

convert test.tif -channel rgb -fill red -draw "rectangle 100x100 400x400" redrect.tif

Thanks for answering my question, really appreciate it.
I tried your exampels setting type and channel. It didnt work.
I just cannot understand these TIF's. If I create a new TIF in photoshop or mspaint theres no problem at all drawing with color. I can save and open it again no problem and the colors are still there. The difference is that these not working tif images has been imported from a scanner with some weird software.

If i use -type truecolor it generetes a corrupt tif

-channel rgb generates a TIF that can be opened but no colors.

I Will try some various things within the day and report later on.

Seems likes IM wont convert rect.tif -fill red -draw "rectangle 100x100 200x200" redrect.tif
at all. Doesnt draw the rectangle. Works with all the other imageformats I tried, jpg,png,gif

post an example of your tif so that the IM folks and others can examine it and test with it
