Thanks for Reply,

I search the samples for "RenderPageToString" and found they are likely to be used to insert in PDF.

What I want to achieve is to paint the PDF in DC at any starting coordinates and size. also I want to modify the colors and removing the page background
The RenderPageToDC paints the PDF from 0,0 (upper left corner).

So I have one option to use RenderPageToDC to paint PDF on memory DC and modify the bitmap as needed and paint it on actual DC using bitBlt. but after process the Image is not good quality as it is raster image. (after increasing the DPI, image is not smooth and affects the performance).

In second method I created the EMF using the RenderPageToFile and drawn on DC. that worked much better.
Now I want to avoid the file operation so instead of "RenderPageToFile", can I use "RenderPageToString"? is it the class or a file stream?

Regards

Abhay

Hi!

Use the search function above
with option advanced,
for all forums,
for any time,
with searchstring "RenderPageToString".

You'll find enough.
First you should be familiar with the sdk - so have a look here:
http://www.quickpdflibrary.com/samples/index.php

Which language and which imagetype doesn't matter.

Cheers and welcome here,
Ingo
