Re: How can I increase the canvas size (add white borders) to various images to make them square?

This does work, however I'm trying to modify it so the original images are automatically deleted / overwritten. The command I posted sets the filename for each output file with this... ... -set filename:f "%[t]_sq" ... Leave the "_sq" out of there and it will make each output fi...

Re: Animated gif with slide transition?

I'm wondering if it's possible, and how, to create an animated gif from a sequence of images where each image slides to the left off the frame as the next image slides in? As snibgo mentioned, using ImageMagick 7 it can be done in a single command with just a handful of individual operations. Consi...

Re: How can I increase the canvas size (add white borders) to various images to make them square?

Thanks. Unfortunately, I've never used ImageMagick before. It sounds like it's fairly simple... Is there any way you (or someone) could come up with the command? I'd appreciate it very much. Using ImageMagick 7 (I'm running it on Windows 10 64) you can do something like this from the command line.....

Re: Can Image magic create an outline around text?

For instance, taking a line of text, adding a red or blue Halo effect, then converting to png. Or even convert to png as black on white background then add the halo. That sort of thing is frequently done by using "-annnotate" twice, something like this (using ImageMagick 7 on Windows 7 64...

Re: Need assistance on colorizing a grayscale image without affecting black/white hues

How would I go about doing this, given these values? Like the idea fmw42 provided above, I'd probably create a color lookup table to apply to the original image. Using IM7 on a Windows 7 64 system I can get a near match to your "background1_edited.jpg" example with a command like this... ...

Re: Crop -- resize camera pics?

My new android phone seems to do 4128x2322 while the tablet conveniently stays with 4:3. So I want to presumably crop to 4:3 ratio but not sure how to set IM to do it. Resizing alters the aspect ratio which I don't want. First I'd check to see if your phone has a setting to take the photos in a 4:3...

Re: Imagemagick caption/label decapitates Å (A-ring)

Unfortunately, for example in "Å", the circle gets cut off. I use the Å character for scientific labels on thousands of images. Some fonts seem to render that character without a problem, but I use mostly monospace fonts and I always have to use some sort of workaround to prevent some or ...

Re: Specific Output Names when Using Convert

I'm a hack at best when it comes to writing scripts. I need to be able to drag and drop images onto the script with no additional input as others besides myself will be using this script. This is currently working well, not sure if that is a fluke or not. As snibgo mentioned, if it's working, it's ...

Re: How to tint image to dominant color?

What I don't understand about your version is the whole color lookup table part - with my limited testing right now, it gives exactly the same result as as the simple "-fill "rgb()" -tint" version from above? It might be more flexible though if you modify the color lookup before...

Re: Center layers relative to each other

How can I automatically center all frames (both vertically and horizontally), without having to manually specify a -page offset for each one? This can be done without much difficulty if you're using ImageMagick 7. Using "ImageMagick 7.0.2-2 Q16 x64" on Windows 7 64, I would use something ...
