Convert EPS to JPEG wrong Bounding Box size ?

[Maskime]

Hi everybody,

I'm trying to convert an EPS file into a JPEG.
So i'm typing the folowing command :

Code: Select all

convert my_eps_file.eps my_jpeg_file.jpg

But the result is not exactly what i expected... The image is really smaller than what photoshop is currently displaying.
so after looking some hours on internet, looking in differents documentation on your site i was able to come with the folowing command :

Code: Select all

identify PAF018050003_L.eps

PAF018050003_L.eps EPT 1656x1242=>397x298 397x298+0+0 DirectClass 16-bit 469.836kb 

First strange thing it's talking about EPT althought my file is an EPS.
Second strange thing 1656x1242 is the size i want the jpeg to be and 397x298 is the converted file size.

I go on and add the verbose option :

Code: Select all

identify -verbose PAF018050003_L.eps

As you can see the Base geometry is 1656x1242 but the ps:HiResBoundingBox is 397.44x298.08+0+0

So here is the question :
How can i tell IM i want the convert to take the base geometry size and not the bonding box size ?

Thanks in advance for any help given.

try adding +repage right after you input image

convert input +repage ...otheroptions... output

Hi,

Thanks, but it doesn't work.
I've tried :

Code: Select all

convert my_eps_file.eps +repage my_jpg_file.jpg

convert my_eps_file.eps -repage myWidthxmyHeight my_jpg_file.jpg

But none seems to work every time i get the tiny picture instead of the big one...

Any other idea that could help me ?

I'm having a similar problem. It seems to me that in order to convert an EPS file created from Photoshop to (say) a JPEG in the correct/same size you need to:
- Determine the base geometry and use this, e.g.
convert my.eps -resize [basex]x[basey] out.jpg
OR
- Identify the density setting as applied by Photoshop and specify that, e.g.:
convert -density 300 my.eps out.jpg

(If you save the EPS in Photoshop with a density of 72, i.e. ImageMagick's default, then convert works as expected).

Here's the problem: how do I determine either the base geometry or density using identify?

Martin

Any news about this??
It seems to be my actual problem:

Photoshop uses the "Base Geometry" size and IM uses the "Geometry" by default.
How to make IM use "Base Geometry" size for conversion.

Can't you just use the density of 300 to do the conversion? Or does dividing the base geometry by the geometry give your the needed density?

[KingCanadian]

I could use the density of 300 to get the correct Geometry.

Is there a way to tell IM to use the density of the EPS automatically?

[fmw42]

You can get the density from string formats in one step and put them into variables, then use the variables in your command line to convert the file. See %x and %y at http://www.imagemagick.org/script/escape.php

In Unix:

Code: Select all

xydensity=`convert -ping image.eps -format "%xx%y" info:`
convert -density $xydensity image.eps image.jpg
