iTextSharp image keep pixel dimensions?

Question

Lets say I have an image that has a DPI of 72 and a width/height of 100px/100px.

However when I add the image and render the PDF, the image that is displayed is bigger than 100px/100px. How can I ensure that the when adding the image to the PDF using iTextSharp that I keep the same pixel dimensions as the original image, in this case 100px/100px?

Answer 1

It sounds like you'll want to check out the ScaleAbsolute method of the iTextSharp.text.Image, which will explicitly set the height/width of an image. There are a couple of related methods you'll want to read up to: ScalePercent and ScaleToFit.

These methods are described in the SourceForge iTextSharp tutorial which includes samples. See tge "Scaling and Rotating the Image" section.
