Bug: Scale bar inside top/bottom right is is partially outside image

[kennethgillen]

Hi,

Using figure 1.2.1 in OMERO 5.2.3:

When adding a scalebar to be 'inside' top-right, or bottom-right, and changing the font size, the scalebar moves outside the image.

The scalebar should move towards the centre of the image when it's increased in size, rather than it being clipped and leaving the image.

Perhaps a separate issue, but it seems once I've chosen to place the scalebar inside the image, not outside the image, it's no longer possible to place it outside again. The only choices are which corner.

I think the main problem here was that there's no pixel size set, so the scalebar has zero length. If the scalebar is longer, it will appear inside the image with the label centred above it. Then it's just a case of making the font small enough for the scalebar since we don't handle overlap very well (see below). I guess this could be improved but it's kinda edge case so not such a big priority.
