(Solved)How to get a part of an image? J# (C# can work too)

[Zethus]

I'm trying to code a map editor to learn new stuff and I've done pretty much everything except when i click on the screen it's gonna draw that picture on so doesn't i know how to get that part of the image I selected. So, can anyone help me on how to get a part of the image?

as stated so do i code in J# but i can often translate C# to J#

and yes I've been searching on google... for hours...
and here's a screenshot of my editor I'm making to just learn new stuff:

Well, when you are blitting images, there should be an optional paramater you can pass for src rect or source or something similar. So you want to blit the tileset image to the map using the src_rect to blit only the part of the image you want to blit. At least that is the way that I do it. I've never done it with any microsoft languages, though so it may be different.

i haven't seen anything about Blit and here's the for when mouse is over it and clicking on it

private void sceneryTilesPic_MouseMove(Object sender, MouseEventArgs e)
	{
		double x = System.Convert.ToDouble(e.get_X());
		double y = System.Convert.ToDouble(e.get_Y());

		x = (x / 32);
		x = Math.floor(x);
		y = (y / 32);
		y = Math.floor(y);

		int xPosition = System.Convert.ToInt32(x * 32);
		int yPosition = System.Convert.ToInt32(y * 32);

		int x2 = Convert.ToInt32(x);
		int y2 = Convert.ToInt32(y);
		sceneryX = x2;
		sceneryY = y2;
		int ID = ((y2 * 10) + x2);
		if (newMap)
		{
			statusLabel.set_Text("Scenery Tile ID: " + ID + " Layer: " + (sceneryLayer + 1));
		}
	}

private void sceneryTilesPic_Click(Object sender, EventArgs e)
	{
		int xPosition = (sceneryX * 32);
		int yPosition = (sceneryY * 32);

		int ID = ((sceneryY * 10) + sceneryX);
		sceneryID = ID;

		sceneryTilesPic.Refresh();
		this.sceneryTilesPic.CreateGraphics().DrawRectangle(new Pen(sceneryRectangleColor, 2), (xPosition + 1), (yPosition + 1), 30, 30);

			tileIDSelected.set_Text("Scenery Tile ID Selected: " + sceneryID);

	}

*The below is from my experience in C#

In the OnPaint method (or whatever you have called your Paint method), you need to use your GraphicsDevice's DrawImage method, using the parameters below:

graphics.DrawImage( image, source, destination, color );

Source is the part of the Rectangle in the Image you want to use, such as the grass tile in RMXP (at pos 0,0 in the image). The Rectangle would be at 0,0 with the dimensions 32,32.

The destination is the part of the Drawing Canvas/Pane/etc. that you are drawing to. It is also a Rectangle. (0,0),(32,32).

I hope this is helpful. Peace.

Thank you. I figured out the code from that and by the way it was:

graphics.DrawImage( Image, Destination, Source, GraphicsUnit);

here's my command for the drawing:

gameScreen.CreateGraphics().DrawImage(sceneryTilesPic.get_Image(), (x * 32), (y * 32), new Rectangle(i, j, 32, 32), GraphicsUnit.Pixel);

SOLVED Thanks to OS Tip
