Hi,

I Need to render PDF pages black and White but also color) in order to pass them to a third Party OCR engine.
I saw that the memory usage is quite intense and I want to ask what the best parameters are to use with the function RenderPageToGdPictureImage()?

I use RenderPageToGdPictureImage(300, true) but there are some over loads and I don't know what to use.

Thank you.
