I am using a variant of bitmap which does not have the .empty property.
On formclose I want to free this item, but there is no valid way to check
its empty property eg
TFastBMP.size/ tbmp.bmHeader.biSize and so on. So Freeing can be an invalid
operation.
So is this valid, or is it leaving an area of memory still being utilised?
tbmp:=nil; tbmp.Free;
Tks,
Al+
