IntersectRect determined whether and where itself two Rechtecke overlap.

Deklaration:

DEf @IntersectRect(3) !User32,IntersectRect

Parameter:

1.Parameter: RECT Structure or 16byte large Memory-Variable, The The Eckpunkte the „Überschneidungsrechtecks“ the Rechtecke from Parameter 2 and 3 angibt.=>
-byte 0-3 = X-Koordinate the left oberen corner the Rechtecks.
-byte 4-7 = Y-Koordinate the left oberen corner the Rechtecks.
-byte 8-11 = X-Koordinate the rechten downstairs corner the Rechtecks.
-byte 12-15 = Y-Koordinate the rechten downstairs corner the Rechtecks.

2.Parameter: RECT Structure or 16byte large Memory-Variable, The The Eckpunkte the first Rechtecks angibt.=>
-byte 0-3 = X-Koordinate the left oberen corner the Rechtecks.
-byte 4-7 = Y-Koordinate the left oberen corner the Rechtecks.
-byte 8-11 = X-Koordinate the rechten downstairs corner the Rechtecks.
-byte 12-15 = Y-Koordinate the rechten downstairs corner the Rechtecks.

3.Parameter: RECT Structure or 16byte large Memory-Variable, The The Eckpunkte the second Rechtecks angibt.=>
-byte 0-3 = X-Koordinate the left oberen corner the Rechtecks.
-byte 4-7 = Y-Koordinate the left oberen corner the Rechtecks.
-byte 8-11 = X-Koordinate the rechten downstairs corner the Rechtecks.
-byte 12-15 = Y-Koordinate the rechten downstairs corner the Rechtecks.

Return Value:

If the Rechtecke from Parameter 2 and 3 overlap, becomes 1 zurückgegeben. otherwise becomes 0 zurückgegeben.
