An image view is a NUI control that displays an image. It is implemented through the Tizen.NUI.BaseComponents.ImageView class.

Creating an Image View

To create an image view:

  1. Create an instance of the Tizen.NUI.BaseComponents.ImageView class and define the image file as a parameter:

    imageView = new ImageView(DirectoryInfo.Resource + "images/gallery-3.jpg");
    

    You can also create the Tizen.NUI.BaseComponents.ImageView class instance separately and define the file path by setting its ResourceUrl property:

    imageView = new ImageView();
    imageView.ResourceUrl = DirectoryInfo.Resource + "images/gallery-3.jpg";
    
  2. To change the image path after the instance has been created, use the SetImage() method of the Tizen.NUI.BaseComponents.ImageView class:
    imageView.SetImage(DirectoryInfo.Resource + "images/gallery-4.jpg");
    

Image View Properties

The following table defines the Tizen.NUI.BaseComponents.ImageView class control properties.

Table: Image view control properties

Property Type Description
ResourceUrl string The file path of the Image.
ImageMap Map Property map associated with a given image.
PreMultipliedAlpha bool Whether the image is opacity-adjusted

If PreMultipliedAlpha is true, the RGB components represent the color of the object or pixel, adjusted for its opacity by multiplication. If false, the opacity is ignored.

PixelArea Vector4 Image subarea defined with relative area values: x coordinate for the top-left corner, y coordinate for the top-left corner, width, and height. To set the subarea as the whole image area, use [0.0, 0.0, 1.0, 1.0].

For example, on a 200 x 200 pixel image, the value [0.25, 0.5, 0.5, 0.5] represents a subarea of that image with the following coordinates:

  • Top left: 50, 100
  • Top right: 150, 100
  • Bottom left: 50, 200
  • Bottom right: 150, 200
Border Rectangle Image border, specified in the following order: left, right, bottom, and top. For N-Patch images only.
BorderOnly bool Whether to draw only the borders. For N-Patch images only.
SynchronousLoading bool Whether the image is synchronous. For N-Patch images only.
