I have found that if I load pictures of <=256 colours via datatypes, then I get a crash when I dispose of the datatype object.
The same code works fine on AROS & OS4, and also for 24-bit pictures on MorphOS! The only way I've found is to stop the crashing is to either use PDTA_DESTMODE,PMODE_V42 or to not provide PDTA_SCREEN.
Can anyone suggest what I might be doing wrong? As far as I can tell, I am not accessing the internals of the bitmap (which V43 disallows).
Here is the offending E code:
Code:
datatypeObject := NewDTObjectA(file, [DTA_GROUPID,GID_PICTURE, PDTA_DESTMODE,PMODE_V43, PDTA_SCREEN,window.wscreen, PDTA_USEFRIENDBITMAP,useFriendBitmap, TAG_END]:tagitem)
GetDTAttrsA(datatypeObject, [PDTA_BITMAPHEADER,ADDRESSOF bitmapheader, TAG_END]:tagitem)
DoDTMethodA(datatypeObject, NIL, NIL, [DTM_PROCLAYOUT, NIL, TRUE]:gplayout)
GetDTAttrsA(datatypeObject, [PDTA_DESTBITMAP,ADDRESSOF bitmap, TAG_END]:tagitem)
and
Code:
WaitBlit()
DisposeDTObject(datatypeObject)
