1.In order to zoom an image by the mouse left button, the function "SetToolType(TOOL_ZOOM_ON_MOUSECLICK)" is set; when the image is zoomed to a certain scale (such as 10 times of original image size), I want to retain the size of the image even if users continue to click the button, whoever has this experience please remark on it.
2.When the image size is larger than the size of display window, the scroll bar is displayed, however, the scroll will shade the right and lower part of the image, which lead to the display error of the image, how can I solve the problem?
Best wishes!

1. You can check the ScaleFactor property if it's larger than the intended limit disable the Zoom Tool.
2-Regarding the shade issue, I'm not sure what you mean. I have checked using one of our demos (see image attached) I didn't see any shades. Can you please elaborate?

Hello,
Thanks for your reply.
1. The key problem is how to catch the mouse click messages before the image is been zoomed. Now I catch the messages in "MsgProcCallBack”, but the image is been zoomed before entering the "MsgProcCallBack" function. Could you give me some advices?
2. When the image size is larger than the size of display window, the scroll bar is displayed. At the same time, the scrollbar cover the right and lower part of the image. How to make the image not to be covered?
From the attached file, you can find the character of "Z" is covered by the scroll bar in the "after.jpg”.
Thanks

Can you create a new small test application (not
your full project) that shows both issues?
If you decide to send me the project please put it in
a ZIP or RAR file first.

Hello,
I have created a sample project. In the project folder, there is a "flow chart" BMP file. That shows what I want to do.
Thanks

The solution to this
is not to use the Mouse Click zoom tool, but implement your own zooming in the MsgProcCallBack.
