Okay, so I have decided to make a simple card maker. The program will 'ideally' allow its user to load a picture from their c drive and it will allow them to change different images while the loaded picture stays the same.

The Problem: I decided to use picture boxes but the problem is picture-boxes are square and in some cases I am using hexagons. So perhaps its transparency I am having the trouble with bu cause my images were made in MS paint.

If anyone has been down this road and can help me with either a new direction to approach this or any easy solutions...feel free. Thanks again for reading.

To paint into irregular shapes, you can use the overloads on Graphics.SetClip() that take GraphicsPaths or Regions. Here's the documentation for the flavor that takes a path: http://msdn.microsof...ibrary/0z994t06

Now your question from the other thread about the "opaque form" is starting to make a little bit of sense. You had the right paradigm of have containers that can hold things, lets you move them around, a paints when you tell them to. Unfortunately, the choice of using the Form control and other WinForm controls is probably not the best choice to implement the paradigm. You will probably be better off implementing something to hold a list of images to be rendered and calling Graphics.DrawImage().

If you really need some transparency effects, there are overloads of Graphics.DrawImage() that take an ImageAttributes parameter. In the ImageAttributes class, you can set color keys for transparency effects.

ok to use this:

private void SetClipPath(PaintEventArgs e)
{

    // Create graphics path.
    GraphicsPath clipPath = new GraphicsPath();
    clipPath.AddEllipse(0, 0, 200, 100);

    // Set clipping region to path.
    e.Graphics.SetClip(clipPath);

    // Fill rectangle to demonstrate clipping region.
    e.Graphics.FillRectangle(new SolidBrush(Color.Black), 0, 0, 500, 300);
}

I would need to create a class with a GraphicsPath Method? What type of information would I need to provide in that Method to get my desired effect?

[Skydiver]

GraphicPath there is a class that is already implemented by the framework. To do your hexagon, you'd probably have to call AddPolygon() and pass in the points of your hexagon.

hmm.... perhaps I don't have a using statement I need. I keep getting this:

Error	1	The type or namespace name 'GraphicsPath' could not be found (are you missing a using directive or an assembly reference?)	C:\Users\Tailean\Documents\Visual Studio 2010\Projects\MyCCG\MyCCG\Form1.cs	26	13	MyCCG

I have: using System.Drawing;

Good instincts there. You should follow them more often.

To help you follow your instincts, it often pays to look at the documentation. In this case, you're having a problem with GraphicPath. Looking in MSDN, we get to the class documentation page: http://msdn.microsof...2d.graphicspath

If you look near the top it says:

Quote

Namespace: System.Drawing.Drawing2D
Assembly: System.Drawing (in System.Drawing.dll)

[Tailean]

In these 2 lines:

private void SetClipPath(PaintEventArgs e)
        {
            clipPath.AddEllipse(0, 0, 200, 100);

            e.Graphics.FillRectangle(new SolidBrush(Color.Black), 0, 0, 500, 300);
        }

Could you tell me what the numbers stand for? (0, 0, 200, 100) 0, 0, 500, 300. I know that's probably a very basic question..I am just unsure..i never worked with this before.

I believe IntelliSense will confirm, but it should be the 4 parameters to define a rectangle: x,y,width,height (where x + y denote the upper-left corner of the rectangle).

EDIT: Just checked the documentation and was correct. You can also pass in an existing Rectangle or RectangleF object.

Please learn to search the MSDN before you ask these questions. Each of these has been answered by referencing the documentation, as shown by the posters. I'm not trying to be harsh, since I know you're fairly new to this, but the documentation is your best friend. Learn to love it. Learn to use it, and you won't be at the mercy of some forum people's free time.

[Tailean]

I hear you, and I did look it up..however...I didn't understand still that's why I asked the question.
