vuo.image

These nodes are for working with 2D images.

In Vuo coordinates, (0,0) is the center of an image. An image has a width of 2, with x-coordinate -1 on the left edge and 1 on the right edge. An image’s height is determined by its aspect ratio, with the y-coordinate increasing from bottom to top.

To use a 2D image in 3D space, you can use the Make 3D Object from Image in the vuo.scene node set.

Example compositions:

• Blend Images: Blends two images into a single image. You can experiment with the Blend Image node's input ports to change how the images are blended.
• Blur Movie: Displays blurred frames in a movie.
• Compare Image Generators: Shows the output of several nodes that generate images.
• Display Image: Displays an image loaded from a file on your computer.
• Enlarge Movie: Crops and enlarges an area of a movie.
• Find Barcode In Syphon Image: Receives video via Syphon, detects a barcode in it, and displays the result on the screen. Try running this composition while streaming live video from an iPhone camera.
• Flip Movie: Displays flipped frames in a movie.
• Mask Movie By Brightness: Applies a brightness mask to a movie.
• Mask Movie With Star: Applies an image mask to a movie.
• Recolor Movie: Applies new colors to a movie.
• Render Text: Makes an image of the text "Hello World!" and displays it on the screen.
• Rotate Movie: Displays rotated frames in a movie.
• Scan Barcodes: Detects barcodes within image files, and displays the information encoded by each one.
• Vignette Movie: Applies a vignette to a movie.
• Warp Image For Fisheye Projection: Warps an spherical image for use in a dome projector.

Nodes:

• Apply Mask (vuo.image.apply.mask): Uses the brightness and opacity of colors in a mask image to control the opacity in another image.
• Blend Images (vuo.image.blend): Blends two images into a single image.
• Blur Image (vuo.image.blur): Distorts the image with a blur effect.
• Adjust Image Colors (vuo.image.color.adjust): Alters an image’s color characteristics.
• Invert Image Colors (vuo.image.color.invert): Alters an image’s colors by replacing each color with its opposite.
• Map Image Colors (vuo.image.color.map): Alters an image’s colors by mapping the image’s brightness to a color gradient.
• Mask Image by Brightness (vuo.image.color.mask.brightness): Changes the darker colors in the image to transparent.
• Crop Image (vuo.image.crop): Outputs only a rectangular part of an image.
• Crop Image Pixels (vuo.image.crop.pixels): Outputs only a rectangular part of an image.
• Find Barcode in Image (vuo.image.findBarcode): Tries to find and decode a barcode in an image.
• Flip Image Horizontally (vuo.image.flip.horizontal): Horizontally mirrors an image.
• Flip Image Vertically (vuo.image.flip.vertical): Vertically mirrors an image.
• Get Image (vuo.image.get): Loads or downloads an image from a URL.
• Get Image Size (vuo.image.get.size): Gives the image’s dimensions in pixels.
• Make Checkerboard Image (vuo.image.make.checkerboard): Creates a checkerboard image.
• Make Color Image (vuo.image.make.color): Creates a solid-color image.
• Make Linear Gradient Image (vuo.image.make.gradient.linear): Creates a gradient that transitions smoothly between the given colors along a straight line.
• Make Radial Gradient Image (vuo.image.make.gradient.radial): Creates a circular gradient that transitions smoothly between the given colors.
• Make Text Image (vuo.image.make.text): Renders an image containing the specified text.
• Pixellate Image (vuo.image.pixellate): Distorts the image by displaying it at lower resolution, so that it has fewer and larger pixels.
• Warp Image with Projection Mesh (vuo.image.project.dome): Stretches an image across a mesh imported from a mesh data file.
• Render Image to Window (vuo.image.render.window): Displays a window containing an image.
• Resize Image (vuo.image.resize): Changes the dimensions of an image.
• Resize Image if Larger (vuo.image.resize.larger): Changes the dimensions of an image if this would make the image smaller.
• Ripple Image (vuo.image.ripple): Distorts the image with a wave or ripple effect.
• Rotate Image (vuo.image.rotate): Rotates an image about its center point.
• Change Wrap Mode (vuo.image.set.wrapMode): Changes the way that areas outside the image are rendered by other nodes.
• Twirl Image (vuo.image.twirl): Distorts the image by twirling it around a point.
• Vignette Image (vuo.image.vignette): Tints the image around the edges.
