Bitmap graphics in Containers change appearance when saved as PDF
Operating system version
OS X 10.8.2
Description of the issue
The main database Table contains one bitmap image per record.
The bitmaps are line drawings at 1000 x 1000px @ 72dpi, in Grayscale format, saved as .PNG files. These images are stored in a Container field.
Several of these containers are brought together in a different layout, which is then Saved as PDF.
-- not relevant here, but noteworthy:
Filemaker PDF's are still quite a mess (these PDF's are often opened and edited in Adobe Illustrator): redundant masks & lines, text lines are broken up into individual characters, etc... very difficult to work with.
Somehow, and this is only since version 12 of FMPro, the PNG graphics become somewhat blurred, lines become thicker, resolution seems to be lowered... It becomes quite noticeable when printed out; the graphics within the PDF are not as crisp as the originals.
Steps to reproduce the problem
1. Import a PNG bitmap into a container field.
2. Save Record as PDF
3. Print out PDF, and compare original graphic to the graphic in the PDF
The graphics in a Container should remain exactly the same as the originals.
No idea if this is related to the (newly designed in V12) Container field, or the PDF saving...
The graphics in a Container field, saved as PDF, are different than the original graphic: lines are thicker, almost "blurred".
Exact text of any error message(s) that appear
No error message
After saving the PDf's in Filemaker, they are often edited in Adobe Illustrator, then printed.
Note: printing of the PDF's has been done in both Apple's Preview app and Illustrator; both yield the same result.
This workaround is not related to Filemaker:
When the graphics are "re-linked" to the original file in its original location (a feature in Illustrator CS6), thus breaking their connection to the PDF, they will appear exactly as they are.
Note: this problem never occurred in previous versions of FMPro.
