Quality of images and/or company logo is poor when view on screen, exporting a report to PDF, or other formats



WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to re-install Windows to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.


On each user’s computer find the following registry key:


HKEY_CURRENT_USER\Software\Seagate Software\Crystal Reports Designer Component\Export


Create two new DWORD values, if they are not already there (see below the screen shot for Terminal Server Instructions):


BitMapMagnifDenominator

BitMapMagnifNumerator


Set them to 1 and 3 respectively; as pictured below…this will yield an average resolution of 240dpi.  If your logo is high color, you might reduce the numerator to 2 or if your logo is mostly line art and you want a higher resolution increase to 4 or 5.  The limit is 12, the higher the numerator the larger your export file will be (too large may prevent e-mailing and actually make printing quality worse), it will also take longer to render the report.  Design Manager recommends no more than 3 or 4 as the setting and 1 or 2 for slower computers or computers with very high resolution displays.


The formula for dpi is:


Bitmap dpi = (BitMapMagnifNumerator / BitMapMagnifDenominator) * screen dpi


Most screens are 72 or 96 dpi. So a numerator of 3 for a 96 dpi screen is 3 * 96 or 288dpi



For Terminal Server and Citrix setups, you must create a group policy for your Terminal Server Users Group and then create a logon script to modify the registry.
