SetAbsolutePosition() accepts 2 floats as parameters. The SetAbsolutePosition() method will do this, but I need to get a calculator out. I have in mind the top right hand corner. Now I want to place the 300 dpi image in a particular position on the page. Increasing the resolution to 300 dpi will reduce the width to 1 inch, and the depth to 2.97 inches (72 points by 213.6 points). So at the default 72 dpi, it will measure 4.17 inches wide by12.36 inches deep. Now, I have a large tif file that I want to use as a logo on an A4 letterhead. Image tif = Image.GetInstance(imagepath + "/mikesdotnetting.tif") The image stays the same in terms of file size but occupies less space in the document.ĭoc.Add( new Paragraph( "TIF Scaled to 300dpi")) What you are actually trying to do is squeeze 300 pixels into the space that 72 normally occupies. To achieve this, you can scale the image to 24%. Generally, commercial printers require that colour images for printing have a resolution of 300 dpi. If this file was being prepared for printing, the final job would be a bit nasty. By default, images are embedded at 72 dpi (Dots Per Inch) which coincidentally, matches the number of points in an inch. It's difficult to tell from the images I have provided so far, but the resolution of the resulting images in the PDF file is not that great.
