Hi,
I noticed that PanNavigator does not work if the bitmap size is smaller than BitmapViewer size in a Windoiws application.
How can I make it working even if the bitmap size is smaller than BitmapViewer size?
Thanks

Hello,
Hm... Do you mean - drag small bitmap inside BitmapViewer's white area? It is impossible, the only thing you can do if bitmap is smaller than control - is to set its alignment.

Hello,
No, you cannot specify image position in such way. You can only set left-top, left-center, etc. alignment via BitmapViewer.ViewportAlignment property of the control.
Could you explain in more detail your task? I wonder why you want move the image arbitrary inside control
? |

Hi Alex, thanks again for your help. Unfortunately what I need would be the "full" control on image position inside the bitmap viewer. Pls have a look at the following screenshot at: http://www.picoodle.com/view.php?img=/4/4/30/f_testm_3bd4b57.jpg&srv=img29This is approximately what I'm developing. The problems are in the "Move section" After zooming (out), If the bitmap width or heigth is smaller than bitmapviewer, I don't know how to have the 4 arrows working properly. Could you please give me your opinion and suggest me any workaround applicable? Thanks

Hello, There are really no workaround with BitmapViewer control - it just was not intended for such tasks. However you may take a look at VectorObjects module of the GraphicsMill for .NET. I think that it is much more suitable for your task. Version 4.x includes MultilayerImageEditor Demo which can be used to evaluate its features. Or, another way - you can find short description and download demo source code from our site. If this way is not acceptable for you for some reasons, I can suggest to implement custom image rubberband, something similar to one implemented in Main Demo print dialog (this demo is also shipped with 4.x versions of GraphicsMill for .NET). |
