large tiff ping problem.

[wizard29]

Hi.
I will try to describe a problem.
Before the start to read an image I call the Magick::Image::ping function. The source file in this case is located on the another machine in our local network. From time to time I caught the application crashes in this case into the Magick::Image::ping function. An exception contains the "Not enough memory" message or somthing like this. The Magick::Image::ping call takes an extremely long time. What can it be?

source image (warning: the image file is about 475Mb)

I use IM 6.9.0 + Magick++.

The image you provided contains a really large 'tiff:37724' profile. We made some changes to improve parsing that file. Identify now only takes half a second instead of 10 seconds on my machine. But on a machine with limited memory you might still get the 'Not enough memory' error because the profile is that large.

The simplest solution is to skip reading the TIFF profiles if ping is enabled. We'll get a patch into ImageMagick 6.9.0-1 Beta by sometime tomorrow.

Hi Guys,
Even I am trying to conver a large tiff file using Imagemagick.
But when I give a convert commad the conversion fails with no message.
Can you please let me know the probable cause.
