My sysadmin is a splendid person! Does anyone have recommendation about what version to shoot for?

Thanks!

Thanks. Output from 6.7.7-10 via the command line doesn't have the background color issue, but is of such low quality that it is unreadable. I'll see what I can do about upgrading. We're running ubuntu 14.04 LTS and I'm not sure what my sysadmin will do for me.

I'm using Perl::Magick to convert PDFs containing black text on a white background to PNGs using ImageMagick 6.7.7-10 2014-03-06 Q16.
The code looks like:

my $image = Image::Magick->new( density => $density,
units => 'PixelsPerInch' );
my $err = $image->Read( $input_path );
if ( "$err ...

thanks snibgo. Aside from the OS, that's pretty close.

Yes, the successes were on newer versions. Unfortunately, Ubuntu is mired in the past.

I tried running one of the failing identify commands under valgrind. At the point where the seg fault occurs, I get the following:

==12994== Warning: silly arg (-21474812544) to malloc()

Thanks for your efforts.

I'm running Linux 2.6.32-40-server #87-Ubuntu SMP Tue Mar 6 02:10:02 UTC 2012 x86_64 GNU/Linux
Ubuntu 10.04.4 LTS

I'll check with my sysadmin, but any other suggestions?

IM 6.5.7-8.

Tried on 7 (~100MB) files. Only one succeeded.

I can put a sample file up on Dropbox or ??

Thanks!

As far as I know (which is not far at all) PICT is essentially an Apple legacy format. Grabbing frames from video doesn't seem to be a high traffic area for QT 7 Pro. The feature has been around for a long time, but has not been carried into the standard QT Player. As far as I can tell, QT 7 Pro ...

Thanks!! I'll forward the issue.

What is creating the PICT image is Apple's Quicktime 7 Pro.

I'll look into using Graphic Converter instead of IM.

Sorry, should have made clear that was the INPUT file as produced by QT Pro. I have no problems with it either.

Try running convert on it to see what you get.

Thanks!

Here's the image:

Thanks fmw42.

The command is in the 1st post in this thread. It's just
convert input.pct -brightness-contrast 10x5 output.pct

I get the same top 20% only result using -auto-gamma or no options at all. Also, trying to convert to JPG (which is the format I want to end up with) produces the same 20 ...

Forgot to explain that the top 20% or so of the image appears. The bottom 80% is white.
