Re: Arrange image to circle

If I for example had a horizontal picture and wanted to bend it to a circle, like this: This example command starts by creating a red-to-yellow gradient image 400 pixels wide by 20 pixels high. Then it adds a transparent border to the top and bottom. Then it uses a version of "-distort" to bend it ...

Re: Arrange image to circle

Supposing I'd change from say 12 to maybe 36 or perhaps 48 dashes: Can your code be simply adapted to that ? That FX expression "%[fx:t*360/n]" tells IM to rotate each input image in the list, designated by the "t", multiplied by 360 degrees divided by "n", the number of images in the list. It will...

Re: Arrange image to circle

how could I arrange multiple of these (named 001.png 002.png ... etc) [...] using only imagemagick ? Assuming you're in the directory containing the input images and that they're in the order you want them to appear in the output, a command like this would accomplish that task... magick *.png -grav...

Re: How to use subshell to crop several coordinates in a single process

Do I need to do a subshell for each pair of coordinates or how to mix in a single process the operations for all the coordinates? You can do everything you have there in a single command by very careful use of nested sets of parentheses. Remember when you set the "-gravity" before your "-smush" ope...

Re: Making semi-transparent white pixels in an image all a single color

I would like to make the figures on the images (which are currently semi-transparent) be totally opaque, and go from the greyish color they are to being totally white (#ffffff). How would I go about this using convert? All of the images also have these different amounts of alpha on the figures, so ...

distort.c has an explicit test for values less than 0.1, throwing an error:
Thanks for looking it over. I'll make sure to use other methods in cases where it might be an issue.

Re: Watermarking images with proportional watermark

Anyone able to help here? Version: ImageMagick 6.8.9-9 Q16 x86_64 2017-07-31 - Linux Inline FX expressions like "%[fx:w+h]" work almost everywhere in IM7 commands, but they only work properly in a few IM6 operations. Fortunately you can use FX expressions in IM6 with the "+distort" operator, which ...

Re: Running batch file only on images recently modified

I run a batch script to modify images in folders and subfolders in windows. It works great, but it runs imagemagick for every single image in the folders. Is there a way to limit the files that are modified to a time period eg. a week from date modified? As the others have mentioned, you'll probabl...

Re: changing the whole color of a png icon preserving the edges alpha

I have another question. In above command how can I fill with gradient instead of solid color and again with preserving alpha? You can use "-sparse-color" to add a gradient fill to the red, green, and blue channels of the input image while keeping the transparency of the alpha channel. A simple exa...

Again the result was the same. It fills the whole of image to that color like following:
Try the same thing only instead of "-alpha off" just work it with the RGB channels like this...

Code: Select all

Re: How to build this effect in Image Magick?

Yes 1/3, 1/3 , 1/3 would be good I think so. If you could give me the command I can adapt it in case I would like to change the proportions. In the example commands above there's a section inside parentheses. That's where you're creating the mask for the gradient overlay. You can use FX expressions...
