RE: [iText-questions] iText question

You'll likely get a rather vague answer from the iText team on this one, I'll try to help.   PDF Files are Vector and Image by default.   A vector file is a scaleable file ie Adobe illustrator, Corel Draw, Freehand; it uses points to create a 2-dimensional shape so there is no set DPI. it can be rendered at any DPI.   An image file is called a raster.  it contains pixels set in a width by height configuration. An image has a dpi. for example, if you have a 10 pixel by 10 pixel image,    *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   * *   *   *   *   *   *   *   *   *   *   you can render this image at 1 inch by 1 inch and it would then be 10dpi.   if you rendered it at .5 inch by .5 inch it would be 20dpi   if you rendered it at 2 inches by 2 inches it would be 5dpi   Does this make sense?   When using iText, you need to resample your images to be the finished dpi you want them to be at the size you are putting it into iText.   for example, if you wanted a 300 dpi image in a 3 x 4 inch box in iText your image would need to be 900 x 1200 pixels.     If you have any other questions, I will try to give you a straight answer.   Thanks, Bill Ensley Bear Printing -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Brian Timmer Sent: Friday, February 27, 2004 3:56 PM To: [EMAIL PROTECTED] Subject: [iText-questions] iText question What DPI does the resulting PDF file use? Is it different between iTextSharp and iText? I'm actually using iTextSharp.   Thanks, Brian Timmer Yeti Software, LLC www.yetisoftware.com
