White boarders after conversion to images

[Martin Hollerweger]

On some Pdfs i get white boarders after conversion to imagges with:
List<Image> images = renderer.render(document, i, i);

I think the pdfs has "cropping" infos which are should be shown or so…
But i couldn't find an option to only render the shown part of the picture.

Can anybody help me?

Hi,

What is the problem exactly: do you need to resize the output page ?

No, i get white boarders on the images despite there are non in the original PDF.

What is the original paper size ?
Is it working better if you use the Ghostscript commande line directly ?

Now i tried it with command line:

First i had the same problem with the boarders: gswin64c -sDEVICE=jpeg -o F:\Sony\ftp\TestOutpu
t\test-%d.jpeg F:\Sony\ftp\PDFs\incorrect\000000874643_SB_01_01-mont-gs902.pdf

I look up for the problem and found the Solution: just adding -dUseCropBox solved my Problem.
Would it be possible to add this in the library??…

Thanks for your quick answers.

I need to add the parameter to the SimpleRenderer… I will do this as soon as I can.
You can also add it yourself in SimpleRenderer Java…

okay, I just changed the parameters. Here is the code:
  //prepare args
        String gsArgs = {
            "-dQUIET",
            "-dNOPAUSE",
            "-dBATCH",
            "-dSAFER",
            "-dFirstPage=" + (begin + 1),
            "-dLastPage=" + (end + 1),
            "-dUseCropBox",
            "-sDEVICE=display",
            "-sDisplayHandle=0",
            "-dDisplayFormat=16#804",
            "-r" + this.getResolution(),
            "-f",
            diskStore.getFile(inputDiskStoreKey).getAbsolutePath()};

Here the explanation -dUseCropBox
Sets the page size to the CropBox rather than the MediaBox. Some files have a CropBox that is smaller than the MediaBox and may include white space, registration or cutting marks outside the CropBox. Using this option will set the page size appropriately for a viewer.

Thank you!
