Heya,I'm trying to display multiple images on a single line in iText in order to replicate the behavior of a web renderer. I tried to do this by wrapping the images in Chunk object, which are themselves placed in the same Paragraph object. However, when there are a lot of images to be displayed, the images get clipped at the bottom of the page. What am I doing wrong? How can I prevent this?
OK, I'm back and I'll start where I left off yesterday. I don't know if you followed the advice I gave you yesterday. If not, please try the example in attachment. If you remove the following line from the code sample:paragraph.setLeading(Math.max(img1.getScaledHeight(), img2.getScaledHeight()));
you get the undesired effect you were described. In other words: you can prevent this by setting the leading of the paragraph to the maximum height of the images. (That's what I meant with my remark yesterday.) br, Bruno
