Hi Lee K,

Thank you for your interest in Syncfusion Products.

Html to Pdf converter make use of MSHTML(IE rendering engine) for converting Html pages to PDF.

With IE 9/10 there is a known issue that it generates only raster image. You can get more information on this from the following link:

http://msdn.microsoft.com/en-us/library/ee330732(v=vs.85).aspx#iviewobject_draw

As explained, to solve this, the key FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI should be updated in the registry.

Please refer the below link.

Hi Lee,

Thank you for your update.

 

Could you please check once again by running the utility with elevated permission “Run as Administrator” and then click “Enable GDI Rendering” to apply the registry changes?

 

Also check by updating the registry in both HKEY_LOCAL_MACHINE (and) HKEY_CURRENT_USER.

I.e., HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI

 

Please let us know if the issue still reproduces.

 

Thanks,

Karthikeyan.C

Hi Karthikeyan C, 
Thank you for the help.
I make sure that the IE Legacy Drawing run as Administrator and found the FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI in HKEY_CURRENT_USER after I clicked "Enable GDI Rendering" (NOT exist in HKEY_LOCAL_MACHINE). The Pdf file still look blear after exporting (see the previous attached file please).
Thanks in advance,
Lee K

Hi Lee,

Thank you for your update.

 

Could you please manually create the key FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI in HKEY_LOCAL_MACHINE also, and try again converting Html to Pdf.

If the issue still reproduces please create a new Direct Trac incident with the title “Forum:107215-Resolution Problem” to get more assistance.

 

Please let us know if you have any concern.

 

Thanks,

Karthikeyan.C
