GDI+ problem (tough!)

[r9]

I have this drawing: private System.Drawing.Graphics graphicsObj = null; private System.Drawing.Pen penBlackWidth1 = new System.Drawing.Pen(System.Drawing.Color.Black,1); private Point[] curvePoints = null; private SolidBrush lightGrayBrush = new SolidBrush(Color.LightGray); private Point point1; private Point point2; private Point point3; private Point point4; private SolidBrush blackBrush = new SolidBrush(Color.Black); ................................................... try { graphicsObj = e.Graphics; graphicsObj.DrawLine(penBlackWidth1, 45, 20, 175, 20); graphicsObj.DrawLine(penBlackWidth1, 45, 20, 45, 120); graphicsObj.DrawLine(penBlackWidth1, 175, 20, 175, 120); graphicsObj.DrawLine(penBlackWidth1, 45,120,90,160); graphicsObj.DrawLine(penBlackWidth1, 175, 120, 135, 160); graphicsObj.DrawLine(penBlackWidth1, 90, 160, 135, 160); graphicsObj.DrawLine(penBlackWidth1, 465, 335, 490, 335); graphicsObj.DrawLine(penBlackWidth1, 580, 335, 605, 335); graphicsObj.DrawLine(penBlackWidth1, 465, 335, 490, 335); graphicsObj.DrawLine(penBlackWidth1, 580, 335, 605, 335); graphicsObj.DrawLine(penBlackWidth1, 473, 345, 483, 345); graphicsObj.DrawLine(penBlackWidth1, 473, 345, 478, 335); graphicsObj.DrawLine(penBlackWidth1, 483, 345, 478, 335); graphicsObj.DrawLine(penBlackWidth1, 587, 345, 597, 345); graphicsObj.DrawLine(penBlackWidth1, 587, 345, 592, 335); graphicsObj.DrawLine(penBlackWidth1, 597, 345, 592, 335); point1 = new Point(592,335); point2 = new Point(597,345); point3 = new Point(587,345); point4 = new Point(592,335); curvePoints = new Point[] { point1,point2, point3, point4 }; graphicsObj.FillPolygon(blackBrush, curvePoints, FillMode.Alternate); point1 = new Point(478,335); point2 = new Point(483,345); point3 = new Point(473,345); point4 = new Point(478,335); curvePoints = new Point[] { point1,point2, point3, point4 }; graphicsObj.FillPolygon(blackBrush, curvePoints, FillMode.Alternate); } catch (Exception ex) { MessageBox.Show(ex.Message); } I want to fill the drawing with a color. From buttom to top. BUT the drawing must be filled accourding to a percent. Is 50%, then only 50% of the drawing must be filled with the color. Natural the fill must newer come outside the drawings edge. Any help? Thank

correction: if 50%, then only 50% of the drawing must be filled with the color.

Since you already have the coordinate points, create a region using these points and then use graphicsObj.ClipRgn() to set the clipping region. Then, you can draw a filled rectangle, without the fill color spilling out of the boundary. Not so tough!! :)

Hi Shree Can you give an example?
