SDK 2023 - Problem with AIAnnotatorMessage->numInvalidationRects

Report · Aug 28, 2023

Hi all,

The following setup is used:

I am in the process of porting our plugin tools to the SDK 2023 (download 14th of August).

Before that I used the SDK 2022 (download November 2022).

A rough summary of our tool functionality:

I press the left mouse-button and drag the cursor.
A specifc area around the cursor is invalidated for annotator-drawing (using sAIAnnotator->InvalAnnotationRect).
When the mouse-button is released, the annotator is deactivated.

After porting to SDK 2023, I am experiencing the follwing difference:

SDK 2022: During the drag-action, the ILPPlugin::Message with selector kSelectorAIDrawAnnotation always delivers a AIAnnotatorMessage with numInvalidationRects value 1.
SDK 2023: During the drag-action (same code), the ILPPlugin::Message only sometimes delivers an AIAnnotatorMessage->numInvalidationRects variable with value 1. Very often it delivers more than one Invalidation-Rect (2 or 3). Furthermore the dimensions of these Invalidation-Rectangles change continuously.

My question is:

How has the AIAnnotator-Draw functionality changed between SDK 2022 and SDK 2023 and how can we come back to the previous behaviour?

Any help would be very appreciated.

We need to find a solution as soon as possible!

Best regards,

Fabian T.
