Write Text on Image
The
Write Text on Image
node in AugeLab Studio is used to write custom text on an input image.The
Write Text on Image
node takes an input image and writes custom text on the image. The node provides controls to customize the font scale, horizontal position, and vertical position of the text on the image.- Node Title: Write Text On Image
- Node ID: OP_NODE_WRITE_TEXT_ON_IMAGE
The
Write Text on Image
node has the following input sockets:- 1.Image: The input image on which the text will be written.
- 2.Text: The custom text to be written on the image. If not connected, no text will be written.
The
Write Text on Image
node has the following output socket:- 1.Image: The resulting image with the custom text written on it.
The
Write Text on Image
node provides the following UI controls:- Font Scale: A slider control to adjust the font scale of the text.
- Horizontal Position: A slider control to adjust the horizontal position of the text.
- Vertical Position: A slider control to adjust the vertical position of the text.
- 1.Drag and drop the
Write Text on Image
node from the node library onto the canvas in AugeLab Studio. - 2.Connect the input image to the Image input socket of the
Write Text on Image
node. - 3.Optionally, connect a text source to the Text input socket of the
Write Text on Image
node. If no text is connected, no text will be written on the image. - 4.Adjust the font scale, horizontal position, and vertical position sliders to customize the appearance and position of the text on the image.
- 5.Run the pipeline.
- 6.The
Write Text on Image
node will write the custom text on the input image. - 7.The resulting image with the text written on it will be output through the Image output socket.
- 8.Use the resulting image for further analysis, visualization, or saving.
- The
Write Text on Image
node uses the OpenCV functioncv2.putText
to write the text on the image. - The font scale determines the size of the text relative to the image dimensions. Higher values increase the text size.
- The horizontal position slider adjusts the horizontal position of the text relative to the image width. Higher values move the text to the right.
- The vertical position slider adjusts the vertical position of the text relative to the image height. Higher values move the text downwards.
- The resulting image will have the same size and type as the input image.
- The
Write Text on Image
node is useful for adding custom annotations, labels, or captions to images for various image processing and analysis applications.
That concludes the documentation for the
Write Text on Image
node in AugeLab Studio. This node allows you to write custom text on an image, customize the font scale, and position of the text, and obtain the resulting image with the text written on it. The node provides UI controls to adjust the font scale, horizontal position, and vertical position of the text. Use this node to add annotations, labels, or captions to images for various image processing and analysis tasks.
