Hi to all,
I hope someone can help me and thanks in
advance:
I am a developer who is trying to display a
section of an image (or algorithm) on a form's device context. Example, if I
have a 5000 lines x 5000 columns (or cells) image, then I need to display only a
section of that, say, the rectangle at location (100,100),(1500,1500) on the
form. Also, that section must completely fill the form, that is to say, scale
un-proportionally.
I have been trying by modifying the
SimpleViewer.cpp example (Visual C++ 6.0) but I am not sure how to do
this.
As my understanding, I need to modify the
following parameters on the algorithm structure:
m_pAlgorithm->canvas_width =
???;
m_pAlgorithm->canvas_height= ???; m_pAlgorithm->output_width = ???; m_pAlgorithm->output_height= ???; m_pAlgorithm->x_offset= ???; m_pAlgorithm->y_offset= ???; The problem is that I don't know if I am on
my correct way and how these parameters must be initialized in order to
accomplish it.
Thanks
Alex
