Hi.

I'm using Leadtools V16 c++ class library

Do you have any example to pan the image exceed the LAnnotationWindow?

because I found in help file:

"LBitmapBase::SetDstRect" ...

This function is not working while being called from the classes LBitmapWindow, LAnimationWindow, or LAnnotationWindow.


thank you~

You can use the built-in mouse tools for panning. You can se the tool by calling LBitmapWindow::SetToolType and passing “TOOL_PANIMAGE” for uToolType argument.
You can also use the LBitmapWindow::ScrollBy and LBitmapWindow::ScrollTo methods to pan/scroll image in LBitmapWindow.

Thanks for reply,

I have try that already, but I still can't find a way to pan the image exceed the window when the image is smaller than the LBitmapWindow.

I used to do that before by LEAD 13 VCL component, ...any suggestion?

If you want low-level control beyond what LBitmapWindow and its children (like LAnnotationWindow) can provide, you can use the LBitmap class (which supports SetDstRect) and implement your own code for painting using LBitmap.Paint()->PaintDC().
If you do that, you can still use annotations, but you will have to create the annotation container and automation objects yourself.

Thanks,
