ColorTable = POINTER TO ColorTableDesc;
ColorTableDesc = ARRAY 256 OF RECORD red, green, blue: BYTE END;
Picture* = POINTER TO PictureDesc;
PictureDesc* = RECORD
width*, height*, depth*: INTEGER;
wth: INTEGER;
bitmap: Bitmaps.Bitmap;
base: INTEGER;
ct: ColorTable
END;
I can resolve by declaring `ct' as `ColorTableDesc', but I am curious
what I do wrong?
Many thanks in advance. </span></pre></div><div class=""><pre style="white-space: pre-wrap; background-color: rgb(255, 255, 255);" class="">
