Problem with Image Coordinates

I have loaded the image to the aurigma component of the resolution 1024x768 and i get the

scroll bars on control to move image up/down and side by side. And I am showing the

X and Y value in the status bar in mouse_move event of the aurigma control. As i scroll the

image to the bottem-right i need to get x= 1024 and y=768. I dont no wats the problem.

Even I tried using the "BitmapToControlCoords" Method and "ControlToBitmapCoords"

Method, but i see it still in the not working state. :(

Please anyone out there to help me on this, Hope to receive your response at your earliest.

Many Thanks

For example :-

If I load then image of height :324 and width :524, and If I take the mouse pointer

to the bottom-right of the image (end point of the image) I need to get the X=524 and

Y = 202. where actually Y should be 324.

Private Sub BitmapViewer1_MouseMove(ByVal button As Long, ByVal shift As Long, ByVal x As Long, ByVal y As Long)
    'a = x
    'b = y
    a = Me.BitmapViewer1.ControlToBitmapXCoord(x)
    b = Me.BitmapViewer1.ControlToBitmapXCoord(y)
    'a = Me.BitmapViewer1.BitmapToControlXCoord(x)
    'b = Me.BitmapViewer1.BitmapToControlXCoord(y)
    Label1.Caption = "X :" & a & " " & " Y: " & b
End Sub

This is extra stuff which i gave a try:

So if i try to draw a polygon considering that i clicked on the 324th pixel point, infact it

considers 202 as the point and the polygon is the not the shape what i deserved.

But my real problem is it failed to get the X and Y of the image. Hope your are understanding

what I am trying to say.

I am online now, please post the reply as soon.

Problem solved, Actually I am using the same old code what I have posted in my previous

reply. I just un-installed and re-installed the component, it started working.

Even I gave a try of event that you specified. but for the image width 1024, X was showing

1095, and for image height 768, Y was showing 955. I dont no how this component is

calculating the co-ordinates.

Anyway, its working for the previous code. Thanks for the help. :)

For Example:- If I have the control placed with the width = 800 and height = 600, and If

I load a Image of width = 400 and Height = 200, The X and Y are displayed correctly.

But If the Image Size exceeds the Control size then the real problem starts.

There I have to pass the X value of the control (mouse_move event of the control) to

ControlCoordsToBitmapX get the exact X position of the Image where ths mouse pointer is,

so same for Y.

If I use the Mouse_move event of the Image then how come its showing the more X and Y

value even the Image is not that of size. Control never moves, only I have to scroll the

image down. In this case If i use the mouse_move event of the control and pass X to

ControlCoordsToBitmapX, I get the correct result.

Anyway its lot of confussion now.

Thanks for the help.
