Re: Crop with virtual canvas wrong offset when negative

I was not able to reproduce Anthony's examples using IM 6.9.10.56 Q16 Mac OSX. But it does work with -extent.

Re: Histogram Y Axis

Yes, snibgo, I would agree. We need your 1D histograms as well as better output image controls.

Re: Histogram Y Axis

Are you talking about the histogram data or the image output? 100% of what? The maximum count? I doubt it would become the default, since that would disrupt past mode of operation and potentially existing scripts. Other changes to the histogram would be useful: 1) ability to set the output image siz...

Re: PDF Bookmarks to individual file names

Imagemagick cannot read PDF bookmarks. But you can number the pages. Just use _%02d appended to the filename. This will work for up to 99 pages. If you want more, then use _%03d. Here I start the scene numbering at 01 rather than 00. First I create a simply PDF file: convert lena.jpg lena.jpg lena.j...

Re: Compress a PNG File

Note that PNG compression is different from JPG compression. See https://imagemagick.org/script/command-line-options.php#quality. What format is your input? If it is compressed highly such as JPG, you will not be able to get a PNG compression to the same file size. Please say a bit more about your i...

magick -list configure

will also show a list of delegates

as will

Re: Getting X11 server to work on MacOS-X

Did you install Xcode.app from Apple? I seem to have that on my Mac. I do not recall if it is needed. But perhaps your XQuartz did not get installed properly? Imagemagick should be installed in /usr/local/bin as I recall. But it depends upon how you installed it. If from Homebrew or from MacPorts, i...

Re: simple conversion of text report to jpg image file

try magick fxDtable.txt fxDtable.gif In IM 7, use magick in place of convert not both. magick commands need an input and an output.

Open a terminal window. Then start XQuartz. Then type magick logo: logo.gif There is no "magicking" and you must have an input and output image. logo: with the colon after it is a special internal Imagemagick image.

Re: Possible bug IM 7.0.8.54 -alpha shape

Testing between IM 6.9.10.56 and IM 7.0.8.56 Mac OSX Sierra (libpng 1.6.36) gives different results. IM 7 result has noise . I note that the tmp files in the command are identical. So it is either -blur or -alpha shape. convert -background none -font Arial -pointsize 140 -strokewidth 14 \( -stroke ...

Seems like my correction post got lost. Here is pretty much what you want, I think. Let me know. All I do is threshold the randomized image at increments and put it into the alpha channel of the input.

Re: Unable to generate PNG from SVG

You are using RSVG renderer -- see the SVG line in your report. You did not have to list everything. I only asked for the SVG line. It converts fine for me when I use Inkscape with Imagemagick. It is better than RSVG, typically. You should try using the command line or PHP exec() to call the command...
