Make a Bitmap Copy cuts off parts of object.

[Tavmjong]

The Make a Bitmap Copy command uses the bounding box of the objects to be
copied. This cuts off the objects edges in the case that a Gaussian Blur
filter is applied or if the Join style is set to 'miter' and the angle
between the two connecting lines is small (bounding box calculation assumes
a 'round' join style).

Tested with 0.45+svn.

Same problem on 2007-11-02 (win32 7z build).

My note on this:

I've managed to create a bitmap copy that clipped off the corners (of a
star). When the "mitre join" option is set for stroke then the stroke lines
exceed the bounding box ("bb"). I imagine this may relate (or be useful to
attack) with the gaussian blur bounding problems reported. Round join
touches the bb; bevel join becomes inset to the bb - which may also cause
problems, perhaps with aligning objects?

The same issue affects bitmap export as png.
Creating a transparent box larger than the object (to force its final size as export bounds) is a workaround, but it's not handy when you want to export multiple objects simultaneously.

[Guillermo Espertino (Gez) (gespertino-gmail)]

This is already fixed. The bbox scales now to fit stroke and gaussian blur widths.

reproduced with Inkscape 0.46+devel r22498 on OS X 10.5.8

re-opening: the second issue "When the "mitre join" option is set for stroke then the stroke lines exceed the bounding box ("bb")." comment #2 is still present.

I propose to separate the two (unrelated) issues:
bug #204820 visual bbox should include blur
bug #168385 visual bbox should include sharp corners of stroke (miter join)

Unlinking as duplicate, since bug still persists (tested with r10313) even though it has been fixed for bitmap export and page resize.

'Edit > Bitmap copy' should probably use 'RENDERING_BBOX' too (slower, but includes all stroke widths):

Duplicate status of #166659 reverted because of recently filed bug #799291 (long miters are still cut off in bitmap copies in current trunk).

[Jonathan Hofinger (jhofinger)]

Closing as part of Inkscape's Bug migration because I'm unable to replicate the issue on current master, neither with stars, sharp corners, blurs, or very weird transforms. In some cases with miter join, the bounding box was even larger than the shape, which in turn causes problems with align & distribute.
