Display using Graphics and Bitmap

Post by oakleaf software ltd »

Just started with the SDK and need a little guidance.
We haveto display the PDF on the screen using either GDI+ Graphics and from the example we can use either

DrawPageToDIBSection
or
DrawPageToDC

I'm currently using DrawPageToDIBSection to create a Bitmap and then using that to display on Graphics using DrawImage - this allows us to control Zoom/Pan in sync with the rest of our display.

Before I do too much more, is there a simpler/better way to achieve the same result.

Many thanks
Phil

Yeah, your method with DrawPageToDIBSection and DrawImage seems like it’s doing the job, especially if you need that control over zooming and panning. But before going too deep, you might want to try using DrawPageToDC directly—it could save you some steps by avoiding the bitmap creation. Also, just a side note, if you’re sending emails to discuss this stuff and want to make sure they’re being read, there’s a way to track if your emails are opened. Anyway, if what you’re doing works, no need to change, but if you can streamline it, why not? Keep us posted if you figure out a better way!
