Re: query settings

I have used -verbose with `identify`, but didn't know it had an effect for `convert`/`magick`. The use case is to check the default values of some settings without consulting the source code.

query settings

Is there a simple way to query the setting of an ImageMagick parameter (e.g., -pointsize or -stroke) using the CLI programs (magick, convert)? Printing the current value to stdout or stderr would suffice.

Re: OSX - display: delegate library support not built-in '' (X11)

Hey BlueWave95. I've also found the ImageMagick binary for Mac to be broken for some time (X11 support was working in the past). Thanks for posting your install route. What did you put in /opt/local/{include,lib} ? Just the delegates suggested by Install-mac.txt? (freetype +bytecode, librsvg, graphv...

Re: current canvas size

Interesting, thanks for clarifying. If I then want to make further manipulations only to the red part, can I add it to a new image list after creation?

Re: current canvas size

Thanks snigbo. In writing 100x%[height], I meant width=100 and height=%[fx:height]. Sorry for being unclear. My system has IM 6.9.10-23, but I've also installed 7.0.9-8 alongside. Is it necessary to write the intermediate image? If I remove the `+write`, your command no longer works: magick 'xc:whit...

current canvas size

Is it possible to specify the size of an element based on the current canvas size? For example: convert 'xc:white[500x300]' \( -size 100x300 xc:red \) -gravity east -composite x: Without prior knowledge that the current canvas is 500x300, could one create the red stripe with width=100 and height to ...

Re: [Resolved]-annotate silently fails on some images

Interesting, I did not know that about crop. Hopefully the documentation will be updated to include this important detail. Regarding the 1x1 pixel image, I did the following before adding text: magick a.png -resize 100x -gravity east -splice 100x0 So there should be space for the text. Thanks for cl...

Re: -annotate silently fails on some images

Thanks GeeMack, your suspicion was correct. Why does the page geometry affect text placement but not the splice operation? That is, the splice occurred in the place expected (immediately to the right of the image), while the font was presumably added somewhere off the page. Also, why does repaging a...

[Resolved]-annotate silently fails on some images

The -annotate option to the magick/convert commands silently fails on some input images. This was found to occur with both of the following IM versions: $ convert --version | head -n1 Version: ImageMagick 6.9.10-23 Q16 x86_64 20190101 https://imagemagick.org $ magick --version | head -n1 Version: Im...

Re: [Resolved]possible bug annotate with negative rotations

I noticed this regression (and then stumbled upon this thread) after a recent upgrade from v6.9.7-4 to v6.9.10-23. fmw42 mentioned that it is fixed in 6.9.10-22 beta, so I assumed it would also be fixed in 6.9.10-23 (a later version; this also happens to be the IM version available in the package re...

-depth operator has no effect

I am using a Q64 version of ImageMagick, and am trying to work with an image at 16-bit instead of 64-bit depth. At 64-bit depth, the pixel values span the 64-bit range (0 to 1.84E19); however, if I use `-depth 16` with the intention of rescaling the pixel values to the 16-bit range (0-65,535), I fin...
