Fitting image into PDF using ITEXT

Question

Hi im having some problems to add the image into the PDF using the itextPDF...

i have more than 10.000 images scanned from original paper in past years, and different sizes/pixels

when i add image into pdf using

img.scaleAbsolute(823,640) or img.scaleToFit(823,640)

doesnt change the result of each image, for example this ones:

First One 654 is the correct one that fit perfectly in the pdf PAGE, the original tiff image has (2048 x 2929)

here image ->

here is the second one 9436 that original tiff image has (1470 x 2057)

look the MARGIN of the pdf in the first and in the second one...

there is a way to make EVERY image like the 654, no matter the original size??

thanks, aprreciate any idea, or i will have to open all the image in paint and edit it :(

Solution 1

Solved for me:

//if you would have a chapter indentation
int indentation = 0;
//whatever
Image image = coolPic;

float scaler = ((document.getPageSize().getWidth() - document.leftMargin()
               - document.rightMargin() - indentation) / image.getWidth()) * 100;

image.scalePercent(scaler);

Solution 2

I know it's an old question, but I was looking for it myself and I've found:

Image image = ...;
image.scaleToFit(PageSize.A4.getWidth(), PageSize.A4.getHeight());

found it useful enough to share here.

If you use margins, you have to substract them from the page width/height otherwise the image will be cut. You can get them from the document (see the validated answer).
