Animation color and speed

Hi,

I am using a LEADRasterView control to show some Dicom images. When a image with multipage displayed as animation, I meet two problems:

1, the speed is too fast and I cannot find a property to control the speed;

2, the colors changed strangely, for example, blue area becomes red, and red area becomes blue. But white and black display normal.

How could I fix them?

 

David,
1. You can control the animation speed using the LEADRaster.BitmapDelay property. You can set the value for different bitmap pages by looping through the BitmapListIndex property (range from 0 to BitmapListCount-1) and setting the delay value for each list item.

2. The color problem is probably related to one of 2 things:
- Either you are not using an appropriate animation palette (LEADRasterView.AnimationPalette property)
- Or you are loading the images in the RGB color model instead of BGR.

Hi Amin,

Thanks for your replay. I got it by using a timer:

'-----------------------------------------------------------------
'Timer_Timer: timer for play animation
'-----------------------------------------------------------------
Private Sub Timer_Timer()
On Error GoTo Err_Timer_Timer
    If mnIndex >= Me.LEADRasterView.Raster.BitmapListCount - 1 Then
        mnIndex = 0
    Else
        mnIndex = mnIndex + 1
    End If
    LEADRasterView.Raster.BitmapListIndex = mnIndex
    LEADRasterView.ForceRepaint
    Exit Sub
Err_Timer_Timer:
    MsgBox "Error occurred when perform timer.", vbCritical + vbOKOnly
End Sub

Now everything is OK, even I could control the speed of animation, show image pages one by one, and the color problem is also fixed but I do nothing for it.

Thank you again.
