I have an image with annotations. I let the user draw a region and perform a crop. The user also has annotations which are outside of his crop area. Once the crop is complete, how do I automatically move ALL annotations within the new image bounds? It has to be easier than getting each individual annotation, determining what type of annotation object it is, determining how many points, then getting each point, and resetting each.

I am using VB.net, leadtools 15.0.0.36

What do you want to do with the objects exactly?


 


Do you want to resize them all (shrink the whole set) so that the new total size will match the new cropped image bounds?


 


Or do you only want to offset them (move them in the X and Y direction) so that they become within the new bounds?


 


If you only want to move them, what will happen to objects that were smaller than the old size, but larger than the cropped image size?

You can do that in one of 2 ways:


1. Either group all the objects and then call the AnnGroupObject.Scale Method.
2. Or call the Scale method for each object in the AnnContainer.Objects collection.


 


Also, if cropping is not symmetrical, you might also need to call the Translate method in addition to the Scale method.
