When I'm using the .NET version of the Graphicsmill control, zooming is very slow... Even in low quality mode.

The tiff image is 8000x6000 pixels. With Imaging Professional zooming is directly done. But with GraphicsMill it's about 4 minutes(!!!) before my zoom action is completed.

The code I'm using to zoom is:

Code:
BitmapViewer.Zoom = (BitmapViewer.Width - 20) / BitmapViewer.Bitmap.Width

The code running is done in about 2 seconds, but the viewer refreshes after 4 minutes (in the meanwhile, my application is using lots of memory)...

Maybe it's a memory leak...

Hello,

Can you submit case with your image and code snippet and we will check it.

BTW, to fit image to width instead of following code:

Code:
BitmapViewer.Zoom = (BitmapViewer.Width - 20) / BitmapViewer.Bitmap.Width

you can use:

Code:
BitmapViewer.ZoomMode = ZoomMode.FitToWidth

I'm sorry... but the images are scanned images from our customers... We can't send them...

I can create a tiff by myself and look if zooming is slow and send you that image...

The code I used voor zooming worked only with GraphicsMill 2... I re-used that code...

But I can use your code as well...

Thank you, please try. We highly appreciate it.

BTW, final version of Graphics Mill 3.0 for .NET has some speed optimizations. It will be available on next week.

I just mailed you an example...

Maybe it's a memory leak... The viewer uses sometimes more than 400 mb...

We tested final version of Graphics Mill with your image, and it works perfectly. Bitmap Viewer resizes image instantly and application doesn't take more then 50 mb in memory.

Final version of Graphics Mill will be available tomorrow. Please test you code with it and let us know whether problem still exists.

Best regards,
