Is there a function to convert the quad points returned from GetPageText(4) to Left/Top/Width/Height values that can be used with the AddLinkToWeb function?

I need to be able to create these annotations programmatically over specific words in a document.

Also is there a way to change the background color of an annotation and set the opacity level?

Any help would be greatly appreciated.

Getting the Left/Top/Width/Height is simple math from the returned quad points. Just remember to use the appropriate pairs based upon your SetOrigin (e.g. for SetOrigin(0), Left/Top are X4, Y4; width is X3 - X4; height is Y4 - Y1)

From the documentation, it appears you can obtain color details via GetAnnotStrProperty (118 = color space) and GetAnnotDblProperty (119-126 are different color components) but curiously these values are not available to the corresponding SetAnnot...Property() functions.

Ok... great. That's what I was doing but on some documents the positions are off.

I did not account for the Origin. I discovered an old post of mine asking pretty much the same question years ago. I'm still using the library the same way. Was just hoping that there might be a better way to do this now.

Thanks for the reply. I'll keep looking for a solution for setting the background color and opacity of the link annotation. If anyone has any ideas, I'd love to hear them.
