I tried to find how do I control the way images are printed on PDF pages when I savetofile(xx.pdf).
As I see, by default each image is printed on a separated page, with a fullwidth or fullheight effect. But I want to print (like a photo album) 2 or 3 pict on each page.
Yes, you can use the PDF exporting functionality of 8.0.0. ImageEn can export layers (including text, images and shapes) as a PDF file page. Try running the Layers_AllTypes demo and using View > As PDF file.
Sorry, but I was reading the source code for SaveToFilePDF method and it seems it is not so complicated to print more than one image on each page. There you are resampling by default to fit each image in a page; I will try to build my own method with TIEPDFBuilder.
