- fixes problems with GDI GetObject function
not working properly when a NULL buffer or 0 count is used.
- note - no attempt was made to fix this
problem under 16-bit windows functions (GetObject16).
Description:
The GDI GetObject function should return the
number of bytes required for the buffer, when a NULL buffer pointer is passed to
the function. However, the implementation in CVS did not provide this
functionality. I've added two function pointers to the gdi_obj_funcs
structure that allow for this functionality. The pointers are
pGetObjectSizeA and pGetObjectSizeW, and for all object types except FONT, they
are implemented by the same function. On FONT, the structure differs
depending on whether the LOGFONTA or LOGFONTW structure is required (depends on
which function is called - GetObjectA or GetObjectW). For bitmaps, the
function must determine which structure is most appropriate (BITMAP or
DIBSECTION) and return the size of that structure - it does so now.
Patch is attached.
