Memory usage in GS 8.63

Hi Brad,

Please send an example file or attach one to a bug report at 

http://bugs.ghostscript.com

In general, 8.63 is much better about memory utilization that the

(obsolete) 8.54 version.

Note that if you are a licensed Artifex customer, then please

email support@... and let us know the customer name

so we can make sure and prioritize the issue.

Best Regards,

Rayi

	Memory usage in GS 8.63 by Brad Ward :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Greetings, We recently upgraded from version 8.54 to version 8.63 which fixed several issues that we were encountering in processing several PDF files. We are passing a command line parameter (-K 1024000 ) to limit the amount of RAM that Ghostscript will use. This is unfortunately necessary because the machines that this runs on also do other processing and we had issues where a badly created PDF would run the server out of memory and start swapping. We are now encountering several PDF's that are requiring 4-8 times or more memory than was previously required under the old version. Does anyone have any suggestions? I'd hate to have to roll back. Here is the command line that we use to execute gs: /usr/bin/gs -dDEVICEWIDTHPOINTS=936 -dDEVICEHEIGHTPOINTS=1598 -dPDFFitPage -dPrinted=false -dUseCropBox -dNOPAUSE -dBATCH -K102400 -dAutoRotatePages=/None -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -sDEVICE=jpeg -sOutputFile=out.jpg -- $1 _______________________________________________ gs-devel mailing list gs-devel@... http://www.ghostscript.com/mailman/listinfo/gs-devel

	Re: Memory usage in GS 8.63 xefitra by Leonardo-21 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Ghostscript still doesn't properly estimate banding buffers when rasterizing transparency, The estimation assumes a fixed number of levels in the transparency stack, but real documents may exceed that limit. Brad please check how many transparency lived do you have. If many, try to set -dBufferSpace manually. The memory consumption is about (levels + 2)*BufferSpace .
