Hello
I'm testing the trial version of Image to PDF Converter.
Image to PDF Converter v2.1
Web: http://www.imagepdf.com
Email: support@imagepdf.com
Release Date: Dec 16 2007
img2pdf.exe -width 596 -height 842 -margin 30x30x30x30 -dpi 300 input.jpg output.pdf
1. I'm expecting the jpg to be centered with 30 margin around and keeping the aspect ratio, so as the jpg is not A4 format ratio, the margin would be different top/bottom to left/right as it cannot be 30 all around.
2. I'm expecting the dpi parameter change the image resolution within the pdf, but I get the same pdf-size dpi 100 and dpi 300 with a hight resolution jpg as input...
3. I'm expecting a compression level for the image within the pdf, but I cannot find one.
4. I need A4 as output format, but with width 596 and height 842 I cannot make it perfect 210x297mm, is there a hidden format switch?
See attachment for expected result.
Many thanks in advance
Kind regards,
Customer
