The following members accept/return PictureEdit objects:

Remarks

The PictureEdit control can display graphics from a bitmap, metafile, icon, JPEG, GIF, PNG or SVG file.

You can specify an image with the PictureEdit.Image or PictureEdit.SvgImage property.

The Properties.SizeMode and Properties.PictureAlignment options specify how the image is sized and aligned.

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:

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);

Masks

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.

Image Preprocessing and Unsupported Formats

The ImageLoading and ImageSaving events fire when a user loads/saves an image via the context menu's Load and Save commands. You can handle these events to perform the following tasks:

  • Pre-process images being loaded/saved.
  • Load/save graphics stored in formats not supported by .NET Framework.
