1. win32eru.ew Query : ATTN : Bernie Ryan
Hi Bernie,
How do I get the size of bitmap file present in the include generated by
win32eru?
In Andy Drummond's grprint.ew, the actual bitmap file is opened and read using
getc() to get the size.
In win32eru.ew the bitmap handles are generated. How can I get the size of these
bitmaps?
Regards,
Rad.

-- once you have a handle you can do this :
atom bm, width, height
-- allocate structure memory for bitmap information.
bm = w32acquire_mem( mset, SIZEOF_BITMAP )
-- fill the structure with the bitmap information.
ok = xGetObject( handle_of_bitmap, SIZEOF_BITMAP, bm )
-- fetch the info that you want
width = fetch( bm, bmWidth )
height = fetch( bm, bmHeight )
