Problem with "convert" from a multipage ps file

[Stefano90]

Hello,

I have a problem with conversion from ps to png file:

I have a multipage ps file with some plots, the first page is converted without any problem, this is the result:
http://188.138.57.168/out-0.png

but the other pages are shifted about 40 pixel on top, and I can't understand the reason:
http://188.138.57.168/out-1.png
http://188.138.57.168/out-2.png
...

This is the code i have used:

Code: Select all

convert -geometry 1300x1300 -density 300 -depth 4 gwrf_merc.ps out.png

I tried also -gravity center, crop function, without any change.

Can anyone help me to solve this issue?

Thank you very much,
Stefano G.

Can you also share your input file and tell us your platform and version of ImageMagick?

Thank you for yuor answer

I uploaded my ps file (an example of 2 pages):
http://188.138.57.168/gwrf_merc.ps

I use CentOS Linux 7.1.1503
The version of ImageMagick is 6.9.2-5 Q16 x86_64

What delegates do you have installed --- what do you get from

Code: Select all

convert -version

Does the list include gs or gslib (Ghostscript)?

[fmw42]

convert -geometry 1300x1300 -density 300 -depth 4 gwrf_merc.ps out.png

-geometry should not be used to resize an image. use -resize. try

Code: Select all

convert -density 300 gwrf_merc.ps -resize 1300x1300 -depth 4 out.png

That seems to work for me on IM 6.9.2.8 Q16 Mac OSX Snow Leopard.

Code: Select all

convert -version

This is the response from convert -version

I tried to copy your new code, but the result is the same:
http://188.138.57.168/out-0.png works fine
http://188.138.57.168/out-1.png cut the upper border

I had not noticed, but mine gets trimmed at the top also. I am sorry, I do not know what else to do. You might try upgrading your Ghostscript.

Mine is a bit old

Code: Select all

gs --version

9.10

[Stefano90]

I have 9.15 gs version.

There is a way to shift down the image? Because if you see the bottom corner, it's trasparent. Seems the "convert" function shift up the real image from "container"

Thank you very much,
Stefano.

As I recall, 9.15 had some problems. Try upgrading.

You can use the -roll function to shift the image. See http://www.imagemagick.org/script/comma ... s.php#roll

You can also pad at the top using either -extent or -splice. See http://www.imagemagick.org/Usage/crop/#extent and http://www.imagemagick.org/Usage/crop/#splice
