Observed on Kubuntu / Lubunt 14.04. Tried LibreCAD 2.0.2, 2.0.4 and daily builds from ppa:
1. Import image
2. Create second layer
3. Draw circles on second layer
4. Snapping to circle center is not working when drawing lines between circle centers.
5. Make layer with drawing invisible: Snapping works.

Seems to be exactly the same as described in ticket #426.

    it was actually implemented as a feature to ignore snap2center within an image.

    I couldn't figure out the rationale of doing so. therefore, decided to fix this bug by enabling snap2center within an image rectangle.

    fixed in commit:

    Thanks for the fast reply. I'll try daily builds as soon as it is available. This will make live much easier for me.

    There's a similar issue for "Snap on entities": can not snap on entities within an overlapped image.

    RS_Image::getNearestPointOnEntity(coord) has to return coord, if coord is within the image rect, to be able to click to select images within the image rect.

    The current workaround is to hide image to snap on overlapped entities.
