preprocessing of images

Hi all,

I'm wondering if there is a standard way in the FOP API to pre-process 
images, i.e. resizing, converting to a specific format, etc... before 
they are included in the resulting PDF? I use FOP 1.0 embedded in a java 
app.

Thanks a lot for your help!

AW: AW: preprocessing of images

Posted by Georg Datterl <ge...@geneon.de>.

Hi Maxine,

We preprocess the images with ImageMagick and put the preprocessed images into the PDF. I don't think there's another way nor will there ever be (in FOP). Maybe you can call a function during the transformation, but I'm no expert there.

Regards,

Georg Datterl

hi Georg,

Thanks for your answer. My question wasn't very precise, sorry. I would like to be able to convert the images referenced in the FO file whatever the attributes. For example, if I have a PNG file referenced in an fo:external-graphic element, I would like to convert the image into JPEG format with a quality of 40% and limit the dimensions to 400x400. This is mostly to provide control on the size of the resulting PDF without having to change the FO file or the referenced images.

Thanks a lot.

hi Georg,

Thanks for your answer. My question wasn't very precise, sorry. I would 
like to be able to convert the images referenced in the FO file whatever 
the attributes. For example, if I have a PNG file referenced in an 
fo:external-graphic element, I would like to convert the image into JPEG 
format with a quality of 40% and limit the dimensions to 400x400. This 
is mostly to provide control on the size of the resulting PDF without 
having to change the FO file or the referenced images.

Thanks a lot.

Hi Maxime,

Fop can work with quite a lot of image types. For resizing there are img attributes.
