AddImageBitmap Function

Adds a System.Drawing.Bitmap to the current page.

Syntax

[C#]
int AddImageBitmap(System.Drawing.Bitmap bm, bool transparent)

may throw Exception()

Params

Name	Description
bm	A .NET Bitmap to be added to the page.
transparent	Whether transparency information should be preserved.
return	The ID of the newly added Image Object.

Notes

Adds a System.Drawing.Bitmap to the current page.

If the Transparent parameter is set to true then any transparency information will be preserved. This allows you to add formats such as transparent GIF and PNG with alpha channel.

The image is scaled to fill the current Rect. It is transformed using the current Transform.

Example

The following code adds a transparent PNG to a document.

using var doc = new Doc();
string path = "../mypics/mypic.png";
using var bm = new Bitmap(path);
doc.Rect.Inset(20, 20);
doc.Color.String = "0 0 200";
doc.FillRect();
doc.AddImageBitmap(bm, true);
doc.Save("docaddimagebitmap.pdf");
