Outline
The WEB program uses the Crystal Report built into Visual Studio. NET as a report development tool.
When you view a report on the WEB, the resolution of the image and the chart is reduced to DPI (for performance and download speed) by default.
How to improve the image quality of the graphic in the report?
Solution
By changing the magnification of the image in the system registry, you can improve the image quality of the graphic in the report.

Warning:
The following decisions include editing the registry. Using Registry Editor incorrectly can cause serious problems and you may need to reload the Windows operating system. The use of the registry will be at your own risk.
It is strongly recommended that you back up the registry files (System.dat and User.dat on the Win9x computer) before you edit the registry.
To learn how to edit the registry
Read the online Help topic for Registry Editor (Regedit.exe), "Change keys and values."

By default, the magnification setting is stored in the registry root key HKEY_CURRENT_USER and is valid only for the current logged-on user. However, when a user is authenticated by IIS through the Web, the user does not have access to the HKEY_CURRENT_USER root key.

To copy the magnification setting to the HKEY_LOCAL_MACHINE root key:
1. Click Start > Run, enter "Regedit" and click OK.
2. Enter Registry Editor and navigate to the following subkey:

5. Repeat steps 3 and 4 to create the item bitmapmagnifdenominator and assign a value of "1".
6. Select the registry subkey export, and then click the Registry menu and select Export Registry File ...
