mapping bitmaps

[atesh]

Can you show me brief code to do this: User selects bitmap files and enters the coordinates for each one to be put onto one large bitmap with all the selected images. Thanks.

Create a new Bitmap with certain dimentions, use it as your drawing surface.

 

Get a graphics object from the Bitmap

Graphics g= Graphics.FromImage(bmp);

 

Draw all the images onto the surface Bitmap.

g.DrawImage();

g.DrawImage();

 

Then in OnPaint or equivalent draw the surface Bitmap

e.DrawImage();

2 questions: (1) How do I create the bitmap to use as my drawing surface? and (2) After I draw the final image can I save it to hard disk as BMP?

[aewarnick]

You can save it to disk as a Bmp, Gif, Jpg, Tif, Png...

You create your surface Bitmap just like any other:

Bitmap b=new Bitmap(300, 200);

Graphics g= Graphics.FromImage(b);

Use g to draw the other images.

 

b.Save("C:\bmp.png");
