Re: problem during executing MagickWand resize method parallel (MultiThread)

We need to reproduce the problem before we can offer any assistance. Detail the steps required to build and run your Java script.

Re: Process images to stdout immediately after they are read from stdin

Try `convert ppm:- -resize 50% ppm:-`. Does that make a difference?

Re: Process images to stdout immediately after they are read from stdin

Your command is flawed. The mogrify scripts reads the MIFF images indefinitely. It won't move to the -resize until it gets an EOF. As it continually reads the images pushed from the convert command, it continues to consume resources until your host throws an exception (such as out of space). As your...

Re: Compilation error IM 7.0.10.0 on linux subsystem for windows with Ubuntu 18.04 LTS

Perhaps you have an older version of the libheif delegate library. Check the heif.h header file. Ours declares heif_context_read_from_memory_without_copy(): // Same as heif_context_read_from_memory() except that the provided memory is not copied. // That means, you will have to keep the memory area ...

Re: What is the difference between PHP GD2 and ImageMagick?

See https://support.pagely.com/hc/en-us/articles/115000052451-Imagick-vs-GD-in-WordPress: Generally speaking, the differences are: GD is generally a slight bit faster when dealing with large images. Imagick supports a larger number of image formats. Imagick is usually better at producing higher qual...

Re: Possible bug -fx min vs -evaluate-sequence min

Could be dumb luck. You would need to add a `debug()` to your `-fx` to trace the reason.

Re: Possible bug -fx min vs -evaluate-sequence min

See https://imagemagick.org/script/fx.php. Notice the min() syntax as min(x, y), minimum of x and y. The Fx parser is fairly forgiving which explains why no exception is thrown for min(x,y,z).

Re: Request for various Pegtop Blending Modes addition

Our implementation matches the algorithm proposed @ http://www.pegtop.net/delphi/articles/blendmodes/quadratic.htm. Freeze is a close analog to Reflect and you suggest Reflect is working-- which in turn suggests Freeze is behaving properly-- unless the algorithm is not correct on the page. We could ...

Re: Cache resource exhausted with specific image

Try

Code: Select all

identify -list policy
if the policies look reasonable, try the command in your "Paperclip gem" environment. Its possible the environment is modifying the polices.

Re: Portable linux version much slower

Its likely slower because the current portable version is not multi-threaded. We will have an updated portable version within a week that is multi-threaded.

Re: problem during executing MagickWand resize method parallel (MultiThread)

The problem must lie within Java. You should be able to create threads in Java and run any command-line utility in parallel. We can help you with ImageMagick, as expected, but not Java.
