IndirectUI: PanAndSlider

One issue which disturbs me using the PanAndSlider property is that if you are panning then it is not possible to drag back to the 0/0 center. You are getting values like 0.02 or -0.01 always.

 

Second: I'm using the following code to setup the background of PanAndSlider:

Bitmap bitmap = new Bitmap(100, 100); // Creates a transparent bitmap
configUI.SetPropertyControlValue(PropertyNames.RotateXYDeg, ControlInfoPropertyNames.StaticImageUnderlay, ImageResource.FromImage(bitmap));

This shows a nice checkerboard background which makes more sense for the plugin than the

standard:

 

Bitmap bitmap = this.EnvironmentParameters.SourceSurface.CreateAliasedBitmap();

Is there a better way than to use these constant values 100,100?

The reason for this is that the calculation of the rectangle for the embedded pan control always sets the value to odd (using  |= 1).

Because of this it is not possible to pan to a center value of 0/0 with the mouse.

I'm no programmer, but from a user's point of view, I find it much more convenient to just click the reset buttons if I want to get to zero, anyways.

That's how a good user interface should work. Every user should be able to use his preferred way to do things. Or?

 

And the zero value is just an example of the issue.
