Pixels per Inch Fr2.5 vs Fr4.0
Hi,
This is pretty basic stuff and I can't believe that I am tripping over it at this stage. I was using Fr2.5 and had lots of reports which used overlays as a form background. In Fr2.5 an A4 page was 756 by 1069 pixels - about 91.4 pixels per inch, or exactly 36 pixels per cm.
Having upgraded to Fr4.0 and starting to convert the old .frf reports to .fr3, I find that the overlay images are incorrectly sized. On Fr4.0, an A4 page is 793.7 by 1122.52 pixels - exactly 96 pixels per inch.
Was there a change in the default resolution between Fr2.5 and Fr4.0? If so, I just need to resample the form images. If not, I must be doing something pretty stupid.
Thanks
Mike

Since the ?«Left,?» ?«Top,?» ?«Width,?» and ?«Height?» properties of all objects
have the ?«Extended?» type, you can point out non-integer values.
The following constants are defined for converting pixels into centimeters and inches:
fr01cm = 3.77953;
fr1cm = 37.7953;
fr01in = 9.6;
fr1in = 96;
For example, a band???s height equal to 5 mm can be set as follows:
Band.Height := fr01cm * 5;
Band.Height := fr1cm * 0.5;
That is useful info. However, I still don't understand how it is that, if I set the page size to A4 in Fr2.5, and look at the page width in pixels, it is 756. If I do the same thing in Fr4.0, the page width in pixels is 794.
It looks like Fr2.5 and Fr4.0 have different cm->px conversion factors, which would suggest that the default page resolution is different.
It's not a major issue. I am just wondering was I doing something stupid in Fr2.5 to get a PPI of 91.4. The Fr4.0 PPI of 96 seems more correct anyway and I will be migrating everything to Fr4.0 (including all those ReportBuilder reports that have caused me nothing but pain over the years [img]style_emoticons/<#EMO_DIR#>/cool.gif" style="vertical-align:middle" emoid="B)" border="0" alt="cool.gif" /> ) Mike[/img]
