Hi,

Is possible to fill a polygon area with a texture? The texture must be created from a little bitmap filled many times in the poligon area.

I see then Freehand hotspot object, but the are is filled by only one stretched image. Is possible to fill the are how I need?

Thanks

Texture fill styles are currently not supported in annotation. 
Some annotations have the ability to contain a bitmap, but the polygon is not one of them.

Hi,
now I'm able to put a texture in the AnnPicture property of the AnnFreeHotSpotObjetct using the Canvascommand. The image that I create is a 2D image, but I need to apply the ViewPerspective command. Applying the command to image, what I obtain is the originale image with the new perspective (good :-)), but the image now as background color in the area outside the Cornerpoints perimeter, and so when I insert it in thr AnnPicture of the AnnFreeHotSpotObjetct I see a wrong image.

How Can I solve this problem with LT14.5 in VB.NET?
Thanks

I'm not sure I fully understand what happens, not can I reproduce it
over here.  Can you please post a small test project that shows the problem?

Thanks,

HI,
is not simple for send you a "small" project. But I attached you some images that could be interesting for you.

Thanks!

So you want to remove this extra background, correct?  If so, then
try setting the Picture.TransparentMode property to UseColor, and the TransparentColor property to the color of the background.

Ok for this, but it doesn't resolve my problem. In order to do what I need I do this:
1-I draw the AnnFreeHandHotSpotObject, representing the surface.
2-From a bitmap I create the texture of the same dimension of the BoundingRectangle of the surface
3-I put the texture in the Picture of the AnnFreeHandHotSpotObject for preview. Util this all is ok. I have the surface perfectly hwo I need.
4-For giving a 3D effect to surface I'm trying to use the PerspectiveCommand, but as you has seen in the example I sent you the texture comes smaller than the surface where I have to put it in, and so I see the backgroud color (the trasparent color doesn't help me this with issue). The only solution I have thinked is to create a texture greater then the surface, so that applying the Perspective Command it comes ever greater then surface.
What do you think about this ? How can I calculate the right dimension of the texture?

It is difficult to come up with an equation that will calculate the
correct size of the pattern before applying the PerspectiveCommand to
it.  Also, such an euqation will work for a specific image
only.  I can't see any way to accomplish this except by trial and error.
