Leadtools.Controls Assembly > Leadtools.Controls Namespace > ImageViewerItem Class : Image Property |
The item can have either a value in Image or SvgDocument but not both. Setting one value will automatically delete the other.
When setting Image to a new value, the previous image will be automatically disposed if the value of AutoDisposeImages is set to true. Note that setting the same RasterImage object into multiple items in the same viewer is supported, and the viewer will only dispose the image if it is the last reference found in all the items. When setting the same RasterImage into items from separate viewers, the ownership and disposing of the RasterImage objects must be handled by the user.
Changing the value of this property will fire the ItemChanged event with ImageViewerItemChangedReason.Image. The value of Resolution will automatically be update as well with the DPI of the new image.
The viewer will subscribe to RasterImage.Changed and automatically perform the necessary updates when the image changes externally by other parts of the application.
Image property of ImageViewer will update this member if this is the active item when the viewer is used in single item mode.
For more information, refer to Image Viewer Items.
