Questions tagged [picturebox]

The PictureBox is a control in the Windows Forms system that provides a way to display an image. It can handle many different image formats.

Summary

The PictureBox control provides a way to display images in a window constructed using the Windows Forms GUI framework. Like all other built-in controls, it inherits from System.Windows.Forms.Control and resides in the System.Windows.Forms namespace.

Important properties

In addition to all of the regular Control properties it inherits, the PictureBox also has a couple additional properties for its intended use.

Image

This property allows you to get or set an Image to be displayed in the PictureBox. Any image format supported by GDI+ can be used for this property. See the "Types of Bitmaps" article on MSDN for a list of supported formats.

SizeMode

This property determines how to display the Image within the PictureBox. It accepts a PictureBoxSizeMode value, which says whether the image should be centered, stretched, etc. (To change the size of the PictureBox control itself, use the ClientSize property.)

Should I use a PictureBox or a Panel to draw on my Form?

Is there a recommended one to use in order to add lines and circles, so I can build a graph? I will possibly work with background images under the graph itself.
