3 to 10 such records occur in sequence. A Solid fill record with a nega- tive Y coordinate indicates the start or end of such a flood sequence. In the start record, the X coordinate indicates the number of vertex records to follow. This is a vector starting at the endpoint last point. The adjusted to point is saved as the last point for use by subsequent vectors.
Subsequent vectors are to be drawn using the color number indicated by the low-order byte.
If a slide contains any vectors at all, a New color record will be the first data record. The order of the vectors in a slide, and the order of the endpoints of those vectors, may vary. The slide consists of a white diagonal line from the lower left corner to the upper right corner of the graphics area, a green vertical line near the lower left corner, and a small red rectangle at the lower left corner. Vector from 572,292 to 0,0. The slide format described above is that produced by AutoCAD Release 9 and later, and is portable among all computers running AutoCAD Release 9 or later.
