Re: Merging two transparent png images AND drawing an outline around them

Your version of ImageMagick does not include OpenMP, which allows multi-threading if you have more cores. My systems had a SSD also. I was actually processing with 7.0.8.1 Q16 HDRI. I would suggest you check your policy.xml file. or just do magick -list policy though that may not actually list your ...

Re: Merging two transparent png images AND drawing an outline around them

I have no idea? What do you get from convert -version? Does it have OpenMP enabled? Are you on a hosted server that may have put limits on your policy.xml file?

The first one I mentioned was using the disk and the second one was using -blur.

Re: Merging two transparent png images AND drawing an outline around them

On my INTEL Mac Mini (2 core) OSX Sierra (8G ram) and ImageMagick 6.9.10.1 Q16, the first script took 2m 55s. The second script took 12 s. To add another color band, just duplicated the two lines for the red, such as magick design1.png design2.png -compose over -composite ^ ( +clone -alpha extract -...

Re: determining the pixel aspect ration of a TIFF

What do you mean by pixel aspect ratio? Do you mean the width/height ratio of the image where the width and height are in pixels? If so, then convert image.tiff -format "%[fx:w/h]\n" info: If on IM 7, then use magick rather than convert. ____________________________ Please, always provide your IM ve...

Re: Merging two transparent png images AND drawing an outline around them

Using disk rather than octagon will produce a much smoother outline. You can fill the gaps with -morphology close at the end. This work for me in Unix syntax. Here is the Windows code: magick design1.png design2.png -compose over -composite ^ ( +clone -alpha extract -morphology edgeout disk:40 -alph...

Re: Sometimes caption: produces text that's too small.

Best fit must consider the font sizes available and not break words. More than than you will have to wait to hear back from one of the developers.

possible bug -alpha shape IM 7

There is a difference in how -alpha shape works between IM 6 and IM 7, but no difference for -alpha copy. In -alpha shape for IM 7, you need to add -negate. I know that IM 7 alpha channels are opposite polarity from IM 6. But I do not think this should be this way as a matter of consistency. Example...

Re: Merging two transparent png images AND drawing an outline around them

This method works for me on IM 7.0.8.1 Q16 Mac OSX Sierra, but is slow due to the size of the kernel and your image sizes. Unix: magick design1.png design2.png -compose over -composite \ \( +clone -alpha extract -morphology edgeout octagon:40 -alpha copy \) \ -compose over -composite \ \( +clone -al...

Re: Compare images script

You can use parenthesis processing to crop only one image or crop each differently within the compare command. But it may be more advantageous to crop all the images ahead of time, so that you do not need to crop them over and over.

Re: Sometimes caption: produces text that's too small.

Sorry, I missed that. When your size just matches the characters you have provided it work well. But when you add one more character, it no longer fits the size and the font must be reduces so that it does not break a word. I find it better to provide a width and pointsize, such as convert -backgrou...
