Destroy HBITMAP ?
Posted: Sat Oct 22, 2022 01:47 PM

hi,

i want to use HB_FUNC(RESIZEBMP) and ::ReadImage() which both "produce" hBitmap

Question : do i need to "Destroy" hBitmap

if Yes, how under Fivewin

Code (fw): Select all Collapse

   aBitmaps := ::oWnd:ReadImage( ::cPath + cFile, { ::nIcoLarge*2, ::nIcoLarge*2 } )
   iImage := aBitmaps[ 1 ]
   iImage := RESIZEBMP( iImage, ::nIcoLarge, ::nIcoLarge, .T. )
   iImage := MAX( 0, ILADD( ::oImageListBig:hImageList, iImage ) )
   // after add to Imagelist what to do with iImage ?

greeting,

Jimmy

for hBitmap,

Code (fw): Select all Collapse

DeleteObject( hBitmap )

Result of FW_ReadImage(...) is an array, whose first 2 elements are { hBitmap, hPallette, ....... }

Use

Code (fw): Select all Collapse

PalBmpFree( aImage )
