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... magick books.png -write...

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, so there ...

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 containing a list of all ...

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...

7.0.8-60 issue with "-background none" and "-swirl"

Using ImageMagick 7.0.8-60 Q16 x64 HDRI on Windows 10, I've been getting unexpected results if I set "-background none" somewhere in the command ahead of a "-swirl" operation. This command produces the following result... magick wizard: -background none -swirl 90 result.png https://www.dropbox.com/s...

Re: Problem with FX expression %[fx:n]

ImageMagick is behaving properly. Querying properties requires an image. In some cases, the user demands a property even if an image is not available so one is automagically created. For example, you might want to perform a FX calculation before an image is read, for example, magick -print "%[fx:.8...

Problem with FX expression %[fx:n]

Using IM 7.0.8-53 Q16 x64 HDRI on Windows 10. The FX expression "%[fx:n]" gives incorrect results when there are no images in the list. Here is an example command... magick logo: -duplicate 5 -delete 0--1 -print "%[fx:n]" null: That should show the number of images in the list as "0", but instead in...

This works well but I would like the annotation text to be 001, 002, etc. rather than 1,2,3,10,13,137.
In many installations the "seq" command will take an argument so it will include the leading zeros in the output. On mine it's "-w". Maybe try something like this...
