Hi,

is possible to insert a RasterImageViewer in a preexisting RasterimageViewer ? I need to modify the bitmap of an AnnStampObject displayed on an image without opening another form, but at the same location?

Thanks!

P.S.: I use LT 14.5 DocImaging with VB.Net.

Sorry,

I resolved this problem, but I have a little issue. The transparent color defined on the second viewer "is not transparent". Why? I have read that the RasterImageViewer.TransparentColor and RasterImageViewer.Transparent works only with GDI+. What does it mean?

Thanks!

How exactly do you display transparency? Do you want to make
a color in the annotation object transparent, or do you want to display a RasterImageViewer image with transparent parts?

Hi,

the second case. I need to display black colored parts as transparent parts.

Thanks.

One way to do that is to define a region in the image that contains all pixels that are NOT


transparent. To do that use the RasterImage.AddColorToRegion Method with a


combine mode of SetNot. Then use the CombineCommand class to move the pixels


of the region (non-transparent) to the second image.
