Vertical Lines appear in converted JPG

Post by nasa »

Hi,

We are using the convert from imagemagick's component in VB6. We have found that some of the converted files have vertical lines appear in the image which we can't explain why it happened when being asked about it. Does anyone can explain this or perhaps has the workaround?

Which version of ImageMagick are you using and have you got a current version of Ghostscript installed? ImageMagick uses Ghostscript to read PDF files.
I can convert your pdf file using IM 6.6.8-4 and Ghostscript 9.00 but I'm using the command line, not VB.

Sorry, my ISP shutdown all personal webspace so my MagickWand Examples in C is offline.
