view a specif part of image

Post by maxvalt » Mon May 18, 2015 7:23 pm

Hello,
is it possibile to view a specific part of an image, when I open a file, without using a scrool bar ?
Thanks in advance.

Hello Massimi,

Could you clarify what you exactly need to do?

Basically I think you will have 2 options:
- 1 Crop the bitmap before rendering it (using the GdPictureImaging class).
- Adjust the view box by using the scrollbar nativation api.

WIth best regards,

Loïc
