Dynamsoft.WPF.Viewer Summary description for ConstStringHelper. Implements the IIndexList interface using an array whose size is dynamically increased as required. Summary description for Util. Clone image. Source image. Return clone of the source image. The original Bitmap.Clone() does not produce the desired result - it does not create an actual clone (it does not create a copy of the image). That is why this method was implemented to provide the functionality. Clone image. Source image data. Clones image from source image data. The message does not clone pallete in the case if the source image has indexed pixel format. Copy block of unmanaged memory. Destination pointer. Source pointer. Memory block's length to copy. Return's value of - pointer to destination. This function is required because of the fact that .NET does not provide any way to copy unmanaged blocks, but provides only methods to copy from unmanaged memory to managed memory and vise versa.

This event is triggered when the selected area of the specified image is deselected and the value of the property is set to false. This event is triggered when an area of the specified image is selected and the value of the property is set to false. This event is triggered when the mouse clicks on an image. This event is triggered when the mouse double clicks on an image. This event is triggered when the mouse moves onto an image. This event is triggered when the mouse right clicks on an image. This event is triggered when the current top image displayed in the viewer is changed and the view mode is NOT set to -1 by -1. Returns or sets the selection rectangle aspect ratio. The ratio is referring to width/height (e.g. to keep width/height 3/2, you can set the ratio to 1.5). This is a runtime property. When an error occurs, please check ViewerException. Please make sure the value is 0 or a positive number. 0 means no limitation on the aspect ratio. Returns or sets the shape of the mouse. When an error occurs, please check ViewerException. When the value of the property is set to true, the cursor is set as a hand. If the width or height of the image is bigger than the control size, scroll bars will be shown and you can drag the image to adjust the position in the control. When the value of the property is set to false, the cursor is set as an arrow. You can select an area in the viewer directly and the OnImageAreaSelected event will be fired. Indicates whether the vertical scroll bar is visible when the images are larger than page size. When an error occurs, please check ViewerException. The default value is true. If view mode is -1 * -1, please ignore this setting. Returns or sets the border color of the selected image. It is a value specifying the 32-bit ARGB value. When an error occurs, please check ViewerException. The default value is Navy. The byte-ordering of the 32-bit ARGB value is AARRGGBB. The most significant byte (MSB), represented by AA, is the alpha component value. The second, third, and fourth bytes, represented by RR, GG, and BB, are the color components red, green, and blue respectively. Returns or sets current selected image indices in buffer. When an error occurs, please check ViewerException. If there is no image in buffer, the returned array count is zero. Returns or sets whether support multiple select. This property is invalid when the view mode is set to -1 by -1 or 1 by 1. When an error occurs, please check ViewerException. The default value is false. If it is true, when a user selects multiple images, the CurrentImageIndexInBuffer is always the minimum index in the selected images. Shows the GUI of Image Printer with the default printer settings.

Note: To enable this function, MouseShape property should be set to false. Specifies the index of the image in buffer. The X axis of the left border. The Y axis of the top border. The X axis of the right border. The Y axis of the bottom border. Returns a boolean value that indicates whether the operation succeeds or not. When an error occurs, please check ViewerException. Gets the selected area on the specified image in buffer. Specifies the index of the image in buffer. Return a Rectangle value that indicates the selected area. Rectangle.Empty means that no area is selected on the specified index image. When an error occurs, please check ViewerException. Clears the selected area on the specified image in buffer. Specifies the index of the image in buffer. Returns a boolean value that indicates whether the operation succeeds or not. When an error occurs, please check ViewerException.

Returns or sets the margin between images when multiple images are displayed in the viewer. When an error occurs, please check ViewerException. The default value will auto judge. Returns or sets zoom factor for the current image, only available when the view mode is set to -1 by -1. This is a runtime property. When an error occurs, please check ViewerException. The zoom value is expressed as a percentage. The valid range is from 2 to 6500 percent (Value: 0.02 ~ 65.0); the default value is 100 percent (Value: 1.0). A zoom value can be specified before or after an image is displayed. When the zoom value is changed, the displayed image will refresh automatically. Returns or sets whether the user can zoom image using hot key. When an error occurs, please check ViewerException. If it is set to true. The user can use hot key "Ctrl + Mouse Wheel" or "Alt + Mouse Wheel" to zoom in/out the image, use "+" (numeric keypad) to zoom in the image, and use "-" (numeric keypad) to zoom out the image.
