ImageResize

The ImageResize node is used to scale 2D images.

Node parameter

  • width：The width of the image after scaling.

  • height：The height of the image after scaling.

  • resize_mode：Zoom mode.

    • INTER_NEAREST：Nearest neighbor sampling.

    • INTER_LINEAR：Linear sampling.

    • INTER_CUBIC：Cubic sampling.

    Note：For specific details, you can search for opencv(C++) corresponding parameters with the same name.

  • image：Sets the visual properties of an image in a 2D view.

    • icon_visOn Open image visualization.

    • icon_visOff Turn off image visualization.

  • image_list：Sets the visual properties of the image list in 2D view. The property value description is consistent with image.

Functional Demo

Use the ImageResize node to scale the 1918 * 1076 image size to 400*400.

Step 1: node preparation

Add Trigger, Load and ImageResize nodes to the node graph.

Step 2: Set the node parameters

  1. Set the Load node parameters:

    • tyepe → Image

    • filename → icon_more → Select image file name （ example_data/images/image.png )

    • image → icon_visOn

  2. Set the ImageResize node parameters:

    • width → 400

    • height → 400

    • resize_mode → INTER_NEAREST

    • image → icon_visOn

Step 3: Connect node

Step 4: Run

Click the Run button of RVS to Trigger the trigger node.

Running result

As shown in the following figure, the results of the Load and ImageResize nodes are displayed in the 2D view. The ImageReize node scales the 1918*1076 image size to 400 * 400.
