#5147 assigned bug

B_OP_BLEND in DragMessage() has no effect.

Reported by: matjako Owned by: nobody
Priority: normal Milestone: R1
Component: Kits/Interface Kit Version: R1/alpha1
Keywords: BView Cc:
Blocked By: Blocking:
Platform: All


Specifing a bitmap with B_OP_BLEND drawing mode, BView::DragMessage() should produce a semi-translucent dragged image (BeOS R5), but it is opaque instead.

Haiku actually knows the difference between a B_RGB32 and a B_RGBA32 color space - are you sure your bitmap has the latter space?

If so, I would like to close this as invalid, as we'd like to keep this incompatibility around.

He said B_OP_BLEND, not B_OP_ALPHA. Haiku indeed does not support that. Or any other mode than B_OP_ALPHA for that matter.

Yes, I meant B_OP_BLEND. This is a convenience mode - it blends any bitmap with background 50-50. Seems almost invented just for that Drag'n'Drop effect ;)
