Issue with "-compose lighten" with IM 7.0.8-68
Using ImageMagick 7.0.8-68 Q16 x64 HDRI on Windows 10. With this release the "-compose lighten" method seems to be broken. With previous versions this command would place the built-in "granite:" image over the built-in "wizard:", and only partially lighten the 128x128 a...

Re: joining images of different dimensions with automatic resizing according to smallest
Can this be done in a single command ? Moreover, if we do not have information about image sizes then is there any operator that joins images vertically after resizing all images in a group to one with lowest y dimension ? This can be done, but a command with IMv6 would be complicated and pretty me...

Re: choose starting frame (different than frame 0) for a GIF
If you want to take some frames from the beginning and put them at the end, you can use "-duplicate" and "-delete" like this... convert input.gif -duplicate 1,0-4 -delete 0-4 result.gif That would duplicate five frames from the beginning, frames number 0 through 4, and place them...

Re: Error image read from windows clipboard (copy from chrome)
Windows 10 has an issue with the way it handles grayscale images in its clipboard that causes alignment problems for ImageMagick. Find a description of this problem from a couple years ago at THIS LINK. Possibly this is a related issue.

Re: Ellipse cropping from GIMP parameters
Is there any method to use x,y,w,h values for oval cropping? The example provided above by snibgo uses "-draw" with "ellipse" to create an ellipse. That's a good simple solution that requires you to define an X and Y center point, and a width and height radius from that point. A...

Re: transparency changes in IM 7
Any ideas how to adjust that? Another method for achieving this result would be to create a transparent canvas first, then read in the main input image, then the shamrock mask. imageMagick's default behavior when doing a "-composite" operation with three inputs is to use the third image a...

Re: Create stack of identical images with transparent overlap
It seems to be the compositing that I'm having a problem with. As soon as I composite the images, the white border comes back again. A single command would be ideal. Do you have an example I can use as a startung point? Here's a command with ImageMagick v7 that does pretty much what you're trying t...

Re: Adding a colored aura around an image
You can do that sort of using distort depolar/polar combination (cartesian to polar and polar to cartesian). Working from your idea of spreading the colors outward from the image, I came up with a few ways to create an aura or halo effect using some other standard IM operations. Method 1... magick ...

Re: Adding a colored aura around an image
How would I go about specifying the color of the aura? If you want the "aura" to follow the contour of the image, you can colorize the image to a solid color of your choice, dilate it, and blur it, then composite the original back over that "aura" with a command like this... mag...

Re: Creating character sheets using IM
Yeah, i think the lack of the red pixels made the screen on the steering wheel render garbled... This command determines where the edge of the character is, then adds a red dot at the top on the third pixel to the right of each character. It uses "-trim" to get the width of the character,...

Re: Creating character sheets using IM
But the dimensions of each box (counting the 1px border of top and left) are of 20x26px, and each character are graviting West, but with the bottom offset half of the top (eg. 4px to the bottom of the box, and 8px of the top). I tried to change the values to suit but i got a disarranged charset. Yo...

Re: Creating character sheets using IM
But what if the font isnt monospaced? I have a Windows script that creates a character display like what you describe. I modified it a bit and tested it with ImageMagick 6.8.9-9 on a bash shell. The first part of it uses a couple "for" loops and "sed" to create a text file conta...

Re: 7.0.8-60 issue with "-background none" and "-swirl"
Why do you need the -background none? I see the same thing with IM 7.0.8.59 Q16 MAC OSX. But I do not understand why you would want the background set to none. The example is just reduced to the fewest operations to show the issue. I often use dozens of operations in a single command, and frequentl...
