InputPictureStream Method

Applies to

IWPTextCursor

Declaration

int InputPictureStream(IUnknown Stream, string FileExt, int Width, int Height);

Description

Insert a picture data specified as Stream.

Parameters:

When using .NET convert an "Stream" using the Stream2WPStream class: TextCursor.InputPictureStream(new WPDynamic.Stream2WPStream(stream1),".PNG",0,0);

Returns

0 if not successful. Otherwise the interface CurrObj can be used to change image properties.

Example 1:

Create a file stream from an image file and insert it.

IWPTextCursor TextCursor = WPDLLInt1.Memo.TextCursor;

FileStream stream = new FileStream(

     "C:\\WPCubedLogo.jpg",FileMode.Open);

TextCursor.InputPictureStream(

    new WPDynamic.Stream2WPStream(stream),"jpg",

 0,0);

stream.Close();

Width and Height are always measured in twips (= 1/1440 inch). If 0, the content width and height will be used.

Example 2:

Create an image "on the fly" and insert it.

Bitmap aBitmap = new Bitmap(320, 200);

Graphics aGraphic = Graphics.FromImage(aBitmap);

System.IO.MemoryStream aStream = new System.IO.MemoryStream();

IWPMemo Memo = wpdllInt1.Memo;

IWPTextCursor TextCursor = Memo.TextCursor;

aGraphic.Clear(Color.AntiqueWhite);

SolidBrush RedBrush = new SolidBrush(Color.Red);

aGraphic.FillEllipse(RedBrush, 10, 10, 300, 180);

aBitmap.Save(aStream,System.Drawing.Imaging.ImageFormat.Bmp);

TextCursor.InputPictureStream(new WPDynamic.Stream2WPStream(aStream), "BMP", 0, 0);

// clean up

aStream.Dispose();

aGraphic.Dispose();

aBitmap.Dispose();

// ReleaseInt was added to TextDynamic V1.31

wpdllInt1.ReleaseInt(TextCursor);

wpdllInt1.ReleaseInt(Memo);
