If it returns 0 then no dpi information is present in the file. The resolution you get from MS Photo editor it's just a default value it puts that matches the screen resolution. You can either arbitrate a value or scale the image according to dimension you want in the page considering that a 100% scale corresponds to 72 dpi.

Thanks for answer.
But, so far it doesn’t work
�
Dpi returns� 0, so no scalePercent.
As result image is over scaled.
�
Any thing else I may try?

This code should work:
Image img = Image.getInstance("my_image.png");
int dpi = img.getDpiX();
if (dpi > 0)
��� img.scalePercent(7200f / dpi);
Note that many times the dpi stated in the file is just a number, usually 300, and bear no relashionship with the original image dimensions.

Paulo Soares

Thanks for answer.
I re read tutorial again, but still can't understand how to embed my
image for 1 to 1 scale.
Would you mind tell me what scale I need to set based on my image
properties? Please.
Image 700 x 300 pixels True Color (24bit)
Also MS Photo editor shows: Resolution 96 Pixels/Inch and size 7.29 by
3.13 Inches.
What I need to put for scalePercent() or for any other method to get in
result PDF not scaled image when PDF goes to Print or displays in 100%
scale?
Thanks a lot.
Best Regards.
Michael.

That's a problem of scaling. See the tutorial for an explanation on
image
scaling and DPI.

Hello,
In my code:
��������������� Image png = Image.getInstance(realPath +"/"+
getFileName());
��������������� png.setAlignment(Element.ALIGN_CENTER);
��������������� document.add(png);
As result in PDF this image is oversized and went out of page, where it
has right size in pixels and looks good in HTML.
What I'm missing?
Thank you.
Best Regards.
Michael.
