You seem to have the Q16 version of ImageMagick installed, so it is saving each pixel as 16 bits. Add -depth 8 before the output filename.

Would you mind explaining what you did?

You might be able to use the MagickWand "wrapper". Start by trying a simple program which just initializes IM and then closes it. Something like this: LOAD DLL "CORE_RL_wand_.dll" CALL DLL "MagickWandGenesis" CALL DLL "MagickWandTerminus" I've assumed that you...

I should have said what version I was using too: 6.3.1 12/24/06 Q8

Would this sort of thing do what you want?: convert logo: -pointsize 36 -font Times-New-Roman -fill rgba(100%,0,0,0.3) -gravity southwest -annotate +0+0 "Hello Wizards Everywhere!" logo_sig.jpg rgba sets the colour to pure red and the alpha to 0.3 Note to the wizards: changing the gravity ...

I'm not sure which composite operator you need but it might work with DstIn instead of DstOut.

I don't know how to do this in PHP and I haven't used that specific technique in C, but I think the command you need will look something like this C function: MagickCompositeImage(magick_wand,mask_wand,DstOutCompositeOp,0,0); where magick_wand is the imported image and mask_wand is, of course, the m...

It is extracting and showing the thumbnail image that is embedded within the jpg file. If you add a -strip argument to your convert command it will remove the thumbnail (and all exif and profiles too) and then XP will show you the actual image because it has to create a thumbnail from the "real...

Windows also has a convert command (I don't know what it does) and that is what is being executed instead of the ImageMagick command.
One way around this is to rename the ImageMagick command to imconvert.exe and then always use the name imconvert.

I was closing the file pointer returned by freopen

That's the correct thing to do. My brain obviously wasn't in gear when I wrote fclose(stdout)!. Sorry.

I couldn't get %f to work with the text subcommand of "draw" (even when I added a coordinate after the text subcommand). But I could get it to work with the annotate command. You also have to put two percents in the string so that DOS doesn't interpret %f as a variable name. Try a command ...

Glad I could help

With IM 6.3.1 and GS 8.53 I got both commands to render the pages if -density is moved after the input filename: Pete

Add +matte before the output filename.

The problem is that Photoshop is getting the dpi from a Makernote in the header. Makernotes are proprietary info put there by, for example, Nikon or Canon when the image was originally produced by a scanner or camera. AFAIK ImageMagick can't read the Makernote. I've done a quick google and can't fin...
