PPS I take it back, Q16 is fast enough :) ImageMagickObject.MagickImage.1 error '80041771' identity: 395: unable to open module file `C:\Program Files\ImageMagick-6.9.0-Q16\modules\coders\IM_MOD_RL_DB_.dll': No such file or directory @ warning/module.c/GetMagickModulePath/672: identity: 420: no deco...

This bit of code gives me an error: convert image.png -magnify imagebig.png I get this: convert: unrecognized option `-magnify' @ error/convert.c/ConvertImageCommand/2030. From what I can tell no value is needed after the -magnify command, based on the limited info availble here and in the manual. I...

Is it the resolution, or is it because gifs only support 256 colors as opposed to millions that other formats do, from wikipedia: "The (gif) format supports up to 8 bits per pixel for each image, allowing a single image to reference its own palette of up to 256 different colors chosen from the ...

The only way you are going to be able to do this nicely is to do each rotation from the base image, not from the previously rotated image.

It looks like IM won't create a directory, or do anything, if there is a directory name in the command. Eg. Convert image.jpg -size 800x1000 C:\home\NewFolder\image.jpg If NewFolder doesn't exist then IM acts like it does something but the rendered image or new dir doesn't exist. Is there a way to m...

Thanks for the response, I think it may be faster for me to do this in Gimp than to figure out the code-y way

Hey all, I need to make several templates with trim marks in the corners. I'm not sure how to do math in IM. To start I would need this: convert -size 2400x3000 xc:white ^ -draw "line 0,0 0,100" ^ -draw "line 0,0 100,0" ^ for the first corner, then -draw "line 2300,0 2400, 0...

Gimp (gimp.org) can open animated gifs as layers that you can delete/change the timing of then output it as an animated gif again. edit: Gimp also can show you a preview of the animation, *I think* its under filter/animation/playback, but not positive since I don't have 2.8 where I am atm. Gimp actu...

Basically I'm trying to achieve the same color shift using only RGB adjustments, but I don't think it will happen, there simply is not enough control.

What I did was to create a layer in Gimp above the original, tweaked the HSL of it, set it to multiply, and reduced the transparency. I've tried just manually tweaking rgb for quite some time, but I'm starting to think it isn't possible without the multiply effect. I will check the identify output w...

I don't think that title makes sense, but this is best explained visually. I have 2 images, an original and one that I made in Gimp using HSL and multiply. The problem is that the program that I am outputting in only has RGB sliders. Can IM tell me the difference in RGB values between two images? Or...

There is an interesting addon for Gimp called FIL which does these effects, basically it is a series of macros.

I use jpeg only when I really have to. If one of your processing steps is to send the image to a printer, does lossy 8-bit jpeg give you any advantages? I doubt it. However, the difference in quality may not be noticable. I'm not sure if the machines will handle a zipped tiff, or even 16-bit images...

Thanks fmw, I'll do some testing to see if it's worth the hassle to use a different file format- the final image is going to print and will get deleted eventually so file size may not be an issue.
