how to convert system.Drawing.Image to system.web.ui.webcontrols.image
-
Is there a way to convert an System.Drawing.Image to an System.Web.UI.WebControls.Image? Im getting the image from database, the binary being in base 64 string. I then convert it back to an array of bytes. My problem is that I can't find a way to create the System.Web.UI.WebControls.Image with a Stream or an array of bytes... I got the Image from Drawing but I can't convert it back to a WebControl Image. I suppose I must write down the file somewhere on the server then return the path but I dont want to leave these temporary images on the drive. Any ideas or suggestion anyone?
Thanks & Regards, Anil Chelasani

No. The namespace is the clue. One is an image, and one is a control that shows an image. You need to write a page that returns the stream of bytes, and point an Image control to it.

Thanks for reply. but the problem is i am converting aspx page to pdf by using third party DLL. Here when i give an aspx URL it will execute that and create a PDF file, but it is not executing the link which is given to ImageURL of the image which resides on the aspx page. Please help me.

Your page should just contain the image, if you've done it right. No third party tool should change that, unless it flat out does not support images.

I have a page (supplier.aspx) which will dispaly the anual report of the suppplier on which i have to show the Logo of that supplier. Logo is in Database so first i have to get that to a page(Logo.aspx) i am doing so it is working properly on the aspx by writing the following line of code in the supplier.aspx.cs.
image.ImageURL="Logo.aspx?supid=4";
Upto supplier.aspx page it is ok it is displaying the logo but when i conert supplier.aspx page to PDF using
pdfConverter.SavePdfFromHtmlStringToFile(pdfData, "a.pdf");
here "pdfData" is html rendered code of the supplier.aspx page. Here is our problem when it converts into PDf it is not displaying the image because it can't execute the path which we had given to ImageURL. It is executing the physical path on the disk and getting the image to pdf from disk but it is not working with aspx page link. So i just want to put directly the image on to the supplier.aspx page without calling Logo.aspx page.
