Re: thinning skeleton

Unfortunately we cannot reproduce the problem. We're using ImageMagick 7.0.8-54, the current release, and we compare the result to that of 7.0.7-28 and we get a zero distortion: $ magick example.png -negate -morphology Thinning:-1 Skeleton result.png $compare -metric rmse result.png exampth7.png nul...

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

ImageMagick is behaving properly. Querying properties requires an image container. 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: magick -print "%[fx:.8765/...

Re: Possible bug IM 6: Inconsistency in getting mean of alpha data?

IMv6 has deficiencies that we addressed in IMv7. This is one of them. We cannot fix the problem you posted.

Re: SVS: compression not supported

SVS is not supported by ImageMagick. It is a proprietary format wrapped in the open TIFF format. See http://paulbourke.net/dataformats/svs/.

Re: "import" blocking keyboard I/O

We received a couple of reports where the drawing rectangle that defines the area to import was not rendering properly. Errant lines would persist as the rectangle was dragged across the screen. Adding a patch to get exclusive access to the X server resolved the problem, see XGrabServer(). The erran...

Re: Possible regression reading DPX files

Can you post a link to a DPX image that throws this exception? We need to reproduce the problem to determine why the exception is thrown and determine if there is a bug or if its a security issue.

Re: Multi-channel EXR support in command-line

The arbitrary channel infrastructure is in place in version 7 series of ImageMagick. We've been looking for use cases (and time) to add the finishing touches for fully-functional multi-channel image support. For convenience, we utilize the EXR delegate library ImfInputSetFrameBuffer() which only ret...

Re: Animate crashes my computer

The animate program loads all the frames in memory and likely thrashes your system. You can reduce memory usage by forcing the pixels to disk:

Code: Select all

animate -limit memory 0 -limit map 0 6b48cf22e4c7d62.gif
For your use case, try firefox or ffplay instead.

Re: Export Speed with ImageMagick

By default, ImageMagick supports HDRI which requires floating-point pixel components. If you build ImageMagick without HDRI support (add --disable-HDRI to your configure script command-line), you get unsigned pixels and will likely result in a substantial speed-up.

Re: Tiff tags are missing in newest version

Add -density 300x300 to your command-line, for example, to export the image resolution.
