Hi, We have a problem after upgrading the hosting environment - we are using IIS 7 installed at a Windows Server 2008 datacentre edition in the Amazon Cloud. Below is a printout of the stacktrace: EO.Pdf.HtmlToPdfException: Convertion failed. Parameter is not valid. ---> System.ArgumentException: Parameter is not valid. at System.Drawing.Image.FromHbitmap(IntPtr hbitmap, IntPtr hpalette) at System.Drawing.Image.FromHbitmap(IntPtr hbitmap) at EO.Pdf.Internal.lu.a(Int32 A_0, HtmlToPdfResult A_1) at EO.Pdf.Internal.lu.d() --- End of inner exception stack trace --- Page Source: http://temp.festivall.dk/print/print.aspx?url=http%3a%2f%2ftemp.festivall.dk%2fapplications%2fartists%2fprint.aspx%3fmxdappid%3d483%26mxdpickup%3debb17d2f5039&admin=1As far as I can Google, the error occurs in FromHbitmap if the bit depth on the server is different from the display, but I might be wrong. What can I do to resolve this issue? Best Regards, Morten

Hi,
Can you check whether you have the latest version? We are not able to find any call to FromHBitmap in our current code base.
Thanks!

Hi eo_support,
The version we are using is:
EO.pdf = 4.0.50.2
EO.Web = 10.0.47.2
It might be an internal call in the image or bitmap class if you are using one of those.
Best,
Morten

Hi,
Do you use GeneratePageImages feature in your code?
Thanks!

Hi,
Thanx for your quick support.
Yes, I actually have that property set to true.
After testing, removing that property also removed the error.
