Using a small, cropped face image as texture after fitting leads to an image access outside domain error

[AdamKortylewski]

BUG:

The code crashes when fitting face images where the face is partially outside of the image.

Please change line 45 in TextureExtraction.scala

Some(target(imagePoint.x + 0.5, imagePoint.y + 0.5))

to

Try(target(imagePoint.x + 0.5, imagePoint.y + 0.5)).toOption

Thank you

Thanks for reporting this error. I think this is a good solution as invisible points are represented as None when accessing them anyway.

see in imageAsSurfaceProperty

As an easy fix you can set the AccessMode of the image with

val outsideValue = ???
image.withAccessMode(AccessMode.Padded(outsideValue))

this way the texture will be filled outside the image with outsideValue.

This will still be possible if we add the Try-toOption fix. But this fix will prevent future crashing and in my opinion it makes sense.
