Custom Component

[EDV Gradl]

Hi Team from Stimulsoft,

I am using a third party component to creat a custom component im the Report Deisner, like in the custom compnent example.

I am writing to a graphics object and set the object to e.Graphics in the Pain event (like in the example)

In the the designer and in the Preview it works fine (I can see my component),

but when printing to the printer my component is not printed. I can set bord to all and the border is printed. Is there anything else I must consider?

Thanks a lot!

Please show source code of method Paint(StiPaintEventArgs e) of your component.

Very easy. I just modified the code from the example:

Code: Select all

	public override void Paint(StiPaintEventArgs e)
		{
			InvokePainting(this, e);
			
			if (!e.Cancel)
			{			
				Graphics g = e.Graphics;

				RectangleD rect = GetPaintRectangle();
				if (rect.Width > 0 && rect.Height > 0 && (e.ClipRectangle.IsEmpty || rect.IntersectsWith(e.ClipRectangle)))
				{
					#region Fill rectangle
				/*	if (this.Brush is StiSolidBrush && 
						((StiSolidBrush)this.Brush).Color == Color.Transparent && 
						Report.Info.FillComponent &&
						IsDesigning)
					{
						Color color = Color.FromArgb(150, Color.Green);

						StiDrawing.FillRectangle(g, color, rect.Left, rect.Top, rect.Width, rect.Height);
					}
					else StiDrawing.FillRectangle(g, Brush, rect);*/
					#endregion
                    GraphicsState state = g.Save();
                    g.SmoothingMode = SmoothingMode.AntiAlias;

                    g.SetClip(rect.ToRectangleF());                                        
                    
                    Barcodes.DataMatrix.DataMatrixControl MyBarcode = new Barcodes.DataMatrix.DataMatrixControl();
                    MyBarcode.DrawMatrixToSize(rect.Left, rect.Top, rect.Width, rect.Height,
                        Barcodes.DataMatrix.Dimensions.dmPixels, g);

                    Debug.WriteLine("Left:" + rect.Left.ToString());
                    Debug.WriteLine("Top: " + rect.Top.ToString());
                    Debug.WriteLine("Width: " + rect.Width.ToString());
                    Debug.WriteLine("Height: " + rect.Height.ToString());

                    g.Restore(state);

					//******************
					//Draw control
					//******************

					#region Markers
					PaintMarkers(g, rect);
					#endregion

					#region Border
					if (this.HighlightState == StiHighlightState.Hide)
						Border.Draw(g, rect, Page.Zoom);
					#endregion

					PaintEvents(e.Graphics, rect);
				}
			}
			e.Cancel = false;
			InvokePainted(this, e);

		}

Try to change this code:

Code: Select all

Barcodes.DataMatrix.DataMatrixControl MyBarcode = new Barcodes.DataMatrix.DataMatrixControl();
MyBarcode.DrawMatrixToSize(rect.Left, rect.Top, rect.Width, rect.Height,  Barcodes.DataMatrix.Dimensions.dmPixels, g);

to this code:

Code: Select all

using (Bitmap bmp = new Bitmap((int)rect.Width, (int)rect.Height))
using (Graphics gr = Graphics.FromImage(bmp))
{
	gr.PageUnit = GraphicsUnit.Pixel;
	gr.Clear(Color.White);
                                    
          Barcodes.DataMatrix.DataMatrixControl MyBarcode = new Barcodes.DataMatrix.DataMatrixControl();
          MyBarcode.DrawMatrixToSize(0, 0, rect.Width, rect.Height, Barcodes.DataMatrix.Dimensions.dmPixels, gr);
                                   
          gr.DrawImage(bmp, rect.ToRectangleF());
}

Sadly, it doen't work.

Now I can't see the component any more. Not in designer, not in preview, not when printing.

Do you have any other ideas?

Thank you very much

Problem solved. Corrected code:

Code: Select all

using (Bitmap bmp = new Bitmap((int)rect.Width, (int)rect.Height))
using (Graphics gr = Graphics.FromImage(bmp))
{
     Barcodes.DataMatrix.DataMatrixControl MyBarcode = new Barcodes.DataMatrix.DataMatrixControl();
     MyBarcode.DrawMatrixToSize(0, 0, rect.Width, rect.Height, Barcodes.DataMatrix.Dimensions.dmPixels, gr);
     g.DrawImage(bmp, rect.ToRectangleF());
}
