(0) Auto scrollbars, if the control requires scroll bars they will be visible and active. Only available if the platform supports scrollbars, otherwise, using this value is the same as using ControlScrollMode.Hidden.

(1) Do not show scrollbars, even if the control requires them/

(2) Disable scrolling, the scrollbars will not be visible nor activated even if the control requires them.

(0) No special sizing

(1) Use the image actual size

(2) Fit the image into the viewing area while maintaining the aspect ratio. If the image size is smaller than the viewing area, no resizing is done.

(3) Always fit the image into the viewing area while maintaining the aspect ratio even if the image size is smaller than the viewing area (in which case, the image will be scaled up).

(4) Fit the image width to be the size of the width of the viewing area while maintaining the aspect ratio.

(5) Fit the image height to be the size of the height of the viewing area while maintaining the aspect ratio.

(6) Fit the image to fill the viewing area. Aspect ratio might not be maintained.

(0) Specifies no trimming.

(1) Specifies that the text is trimmed to the nearest character.

(2) Specifies that text is trimmed to the nearest word.

(3) Specifies that the text is trimmed to the nearest character, and an ellipsis is inserted at the end of a trimmed line.

(4) Specifies that text is trimmed to the nearest word, and an ellipsis is inserted at the end of a trimmed line.

(5) The center is removed from trimmed lines and replaced by an ellipsis. The algorithm keeps as much of the last slash-delimited segment of the line as possible.

(0) Run the interpolation one page at a time, waiting for one page to complete before starting the next. This is the default.

(1) Place no limit on the number of pages that can be interpolated at once.

(0) No interpolation. Default rendering by the platform.

(1) Use bilinear interpolation (resample) if the render operation needs to resize the image when zoom value is less than 1:1. This mode works for both bitonal (black/white) and color images.

(2) Enables grayscaling of bitonal images (such as black and white) if the render operation needs to resize the image when zoom value is less than 1:1. This mode produces slighly better result if the original image was black and white. However, in almost all cases, Resample produces similar results in quality and speed and should be used for all images.

(0) New interpolation has started.

(1) Interpolation has completed successful and the image is updated.

(2) Interpolation has been aborted successfuly either because another render has occured or by user interaction.

(3) An error has occured and interpolation has been aborted.

(0) Do not render the region.

(1) Trace the region outline using a fixed frame.

(2) Trace the region outline using an animated frame.

(0) Point is in control (client) coordinate. For example obtained from a mouse or touch event

(1) View coordinate. Transform using ImageViewer.ViewTransform

(2) Item coordinates. Transform using ImageViewer.GetItemTransform

(3) Content coordinates. Transform using ImageViewer.GetItemContentTransform

(4) Image coordinates. Transform using ImageViewer.GetItemImageTransform

(5) Floater coordinates. Transform using ImageViewer.GetItemFloaterTransform

(0) Do not use a part of the item. Can be used with ImageViewer.GetItemBounds to mean the full bounds in view coordinates. Returned from ImageViewer.HitTestItemPart to mean the point is outside the item (in the view)

(1) The item boundary. This is Content plus item margin, border and padding (ImageViewer.ItemMargin, ImageViewer.ItemBorderThickness and ImageViewer.ItemPadding respectively)

(2) The content bounds. This is Item minus item margin, border and padding (ImageViewer.ItemMargin, ImageViewer.ItemBorderThickness and ImageViewer.ItemPadding respectively)

(3) The image bounds. Inside Content and based on the image size (ImageViewerItem.ImageSize) and alignment (ImageViewerItem.ImageHorizontalAlignment and ImageViewerItem.ImageVerticalAlignment)

(4) The area where the text is rendered. Actual size is based on font size and value of ImageViewerItem.Text

(5) The text bounds, outside the content bounds

(6) The floater bounds. This could be outside the item boundary depending on ImageViewerItem.FloaterTransform

(0) None of the properties will reset back to their default values.

(1) The horizontal and vertical scroll offsets (ImageViewer.ScrollOffset) location will reset back to the top-left position (0,0)

(2) Reset ImageViewer.ScaleFactor back to 1.0 and ImageViewer.SizeMode to ControlSizeMode. This will call Zoom to set these values.

(4) Reset ImageViewer.Flip, ImageViewer.Reverse and ImageViewer.RotateAngle back to false, false and 0 respectively.

(8) Resets ImageViewer.Invert back to false

(16) All the properties will reset back to their default values

(0) The item size has changed

(1) The item transformation has changed

(2) The item IsEnabled value has changed

(3) The item IsSelected value has changed

(4) The item IsHovered value has changed

(5) The item Text value has changed

(6) The item Url value has changed

(7) The item was the target of a drag/drop and the image data has changed

(8) The item was the source of a move drag/drop operation and the image data has changed

(9) The item Image or Canvas value has changed.

(10) The item Image has changed. This is when the image itself has changed, for example, the user inverted or flipped the image data.

(11) The item Floater value has changed

(12) The item FloaterTransform value has changed

(13) The item BackImageUrl value has changed

(14) The item BackImage value has changed

(0) The object is first dragged over the item.

(1) The object is dragging over the item.

(2) The object is dragged out of the item.

(3) The object is dropped on the item.

(0) Drag target can be the same or any other ImageViewer in the application.

(1) Drag target can only be the same ImageViewer that initiated the operation only and not any other ImageViewer instances in the application.

(2) Drag target can be any other ImageViewer instance in the application but not the ImageViewer that initiated the operation.

(0) Do not set Item. Leave it as it is.

(1) Do not use Item, always treat is as null, ImageViewerSelectItemsInteractiveMode uses this value since it never works on a specific item.

(2) Perform hit-testing and if any is found, set it in Item. If no item is found then the mode will not work.

(3) Perform hit-testing and if any is found, set it in Item also make it the current ActiveItem. If no item is found then the mode will not work.

(0) No selection. Items selection state cannot be changed.

(1) Only one item can be selected at a time.

(2) Multiple items can be selected at any time.
