Re: convert: unable to write pixel cache

Either increase the free space on your temporary partition or set the MAGICK_TMPDIR environment variable to write to a path with plenty of free disk space. ImageMagick returns the exception you received when it runs out of free disk space.

Re: Use-after-free in TIFFSetField()

The stack trace shows the fault occurs withing the libTIFF delegate library. ImageMagick calls libTIFF's TIFFGetField() to obtain a private tag profile 37724 (used by Adobe). TIFFGetField() returns success with a length of 9908 bytes and a data buffer to the location of the profile. Unfortunately th...

Re: Heap out of bounds read in .omp_outlined..68()

Unfortunately we cannot reproduce the problem. We're using the latest Github head, Ubuntu 16.04.3, and gcc 5.4.0. Add --disable-openmp to your configure command-line and install. Does the problem still exhibit for you? Is the problem intermittent or random?

Re: Tiff - Null count for "RichTIFFIPTC"

ImageMagick supports warnings and errors. The TIFF delegate library pushes an error for this exception rather than a warning. Its up to you to decide if you want to continue processing an image after an error is thrown. In many cases, errors prevents further processing because it might be a security...

Re: Tiff - Null count for "RichTIFFIPTC"

The exception is pushed from libtiff. ImageMagick just reports it. The image can still be identified, converted, or viewed with ImageMagick.

Re: PSB File handlling error

Size is not the issue. Unless we can download and reproduce the problem, we can't help. You could post the image to one of the free download services such as Dropbox and post the URL.

Re: PSB File handlling error

We may have an overly aggressive check in our PSD reader. Can you post a URL to your image so we can download it, reproduce the problem, and generate a patch to fix the problem. Thanks.

Re: "Trace/BPT trap: 5" when do resize() sometime. Only with: --with-opencl. MacOS X with NVidia GTX 980 G1.

We ran your demo over 10,000 times and did not get any faults. We're using ImageMagick 7.0.6-8 and gcc 7.1.1 under Fedora and CentOS. You could try building ImageMagick without enabling OpenMP (e.g. ./configure --disable-openmp). What is the width and height of your 1.png image?

Re: I obtain rare effect when I scale a image in imagemagick

If you scale by whole integers 200, 300, and 400%, for example, no new colors are introduced. The scanlines are duplicated. However if you enlarge by a non-integer factor, new colors are introduced. Scanlines are blended. 270% is a factor of 2.7. So in the example you provide, new colors are expected.

IMv7 Beta is ready for testing. Use CubicSpline and define filter:lobes={2,3,4}.

Akira, what is your preference? -define filter:lobes={2,3,4} or -define:support={2,3,4}?

Re: High tap count Spline filters? (Spline36/64/100/144/196/256)

Spline 16 has a support size of 2, spline 36 is 3, and spline 64 is 4. You set the support size with the filter:support size.

Re: High tap count Spline filters? (Spline36/64/100/144/196/256)

Here's the latest: Use -define filter:support={2,3,4} to specify the support size for filtering for the CubicSpline filter.
