Re: Windows: Postscript Delegate: Concurrent PS/EPS read operations fail

Any news on this issue? We worked around this by adding a lock in case of Windows. On Windows, ImageMagick loads the GhostScript DLL and uses GhostSCript in-process - the DLL must not be used concurrently. On Linux, ImageMagick uses GhostScript out-of-process, so the issue cannot occur.

Thanks!

Re: Windows: Postscript Delegate: Concurrent PS/EPS read operation fail

Thanks. However, I don't think that this can be reproduced using convert alone because it does not execute multiple conversions concurrently - in a single process. My understanding is that the thread limit of convert is a limit for a single conversion. That's why I provided the testcase.

Re: Windows: Postscript Delegate: Concurrent PS/EPS read operation fail

Thanks for the reply. ReadImage fails so my assumption is that the output format does not matter for the issue. The EPS I used: https://people.sc.fsu.edu/~jburkardt/data/eps/circle.eps Actually, I tried multiple files and always had the problem. I found the following ImageMagick changelog entry: 201...

Thanks. I retried with 9.23, the issue still exists.

Windows: Postscript Delegate: Concurrent PS/EPS read operations fail

ReadImage fails on Windows with ImageMagick 6.9.10 and GhostScript 9.06 if multiple threads execute these operation using dedicated ImageInfo instances. The output (1 thread): C:\>main 1 circle.eps test.jpg Start READ Start WRITE END The output (2 threads): C:\>main 2 circle.eps test.jpg Start READ ...

Update from 6.5.8 to 6.8.6-7: PSD PingImage reads full data

In 6.5.8, executing PingImage for a large 100MB PSD file returned immediately with no recognizable delay. In 6.8.6-7, PingImage takes around 30 seconds to complete. I assume that all PSD files are affected because 6.8.6-7 does not evaluate the ping flag in ImageInfo anymore, so I did not provide a s...
