The PictureEdit control can display graphics from a bitmap, metafile, icon, JPEG, GIF, PNG or SVG file.
Context Menu and Image Editor
You can use the commands in the PictureEdit's context menu to perform common operations: cut, copy, paste, delete, edit, load, save and zoom. The following properties control the availability of the menu and its commands:
- Properties.ShowMenu - Specifies if the context menu is displayed when users right-click the image.
- Properties.ShowZoomSubMenu - Specifies whether the context menu contains zoom-related menu commands. When the zoom sub-menu is enabled, a user can also zoom the image with the mouse and keyboard. See Properties.ShowZoomSubMenu for more information.
- Properties.ShowCameraMenuItem - Specifies whether to display a command that allows users to take a snapshot from a webcam.
Properties.ShowEditMenuItem - Displays the Edit command that invokes the Image Editor.
The Image Editor dialog provides basic image edit operations:
- Crop and straighten
- Adjust brightness, contrast and saturation
To open the Image Editor from code, use the PictureEdit.ShowImageEditorDialog method.
Fit Image in Control Bounds
The Properties.SizeMode property specifies whether and how an image is stretched within the control's bounds.
In specific instances, you may want to resize the PictureEdit in code so that its image fits the control without padding. In this case, additional space must be reserved to paint the control's focus rectangle. Otherwise, a few pixels are clipped out from the image. The correct code to resize the PictureEdit and allocate space for the focus rectangle is as follows:
mPictureEdit.ClientSize = new System.Drawing.Size(mPictureEdit.Image.Width + 2, mPictureEdit.Image.Height + 2);
The Properties.OptionsMask.MaskType setting (accessible from the Properties.OptionsMask object) enables masked mode to mask a part of the image.
Circle, rounded rectangle, and custom shape mask types are available.
