QR Code
Generates a QR code image
QR Code
Method #
This node generates an image of a QR code from a given string. A QR code is simply an encoded string of text, and so are ideal as a quick link to a URL. The generated QR code is adaptive, and so will expand and contract based on the length of text added as it needs to.
Although most QR codes are predominately black and white, they do not have to be. A QR code can be any colour and can even include more than 2 different colours. The key takeaway is that the QR scanner is able to distinguish between foreground and background modules (the squares) in order to detect the pattern and decode the string contained within it.
This node can be connected to any node which accepts an image input.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Control the inheritance of the transforms from the parent.
These properties control the core behaviours of the node.
Parameter Details Active Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Preview In Viewport Preview the effect blended with alpha in the viewport.
Width The resolution of the effect along its width.
Height The resolution of the effect along its height.
Update Time Mode How the generator updates with relation to the timecode.
- Locked To Timecode : The generator animations are locked to the timecode and the same time will always yield the same result.
- Running / Loopable : The generator animations are disconnected from the timecode and will loop seamlessly at the end of the layer.
Text String The string of text to encode in the QR code.
Error Correction Level The error correction level. A higher ECC level will yield a barcode that tolerates more damaged parts while preserving the payload data.
- Low : A low error correction level. The QR Code can tolerate about 7% erroneous codewords.
- Medium : A medium error correction level. The QR Code can tolerate about 15% erroneous codewords.
- Quartile : A quartile correction level. The QR Code can tolerate about 25% erroneous codewords.
- High : A high error correction level. The QR Code can tolerate about 30% erroneous codewords.
Version Range Min The minimum version range. Different versions have a different amount of modules. Eg. Version 1 has 21x21 modules and version 40 has 177x177 modules.
Version Range Max The maximum version range. Different versions have a different amount of modules. Eg. Version 1 has 21x21 modules and version 40 has 177x177 modules.
Border (in Modules) The size of the border around the modules within the QR code.
These properties control how the generators are coloured and blended with other images.
Parameter Details Colour Change the colour of the generated image.
Blend Amount The amount the generator is blended with the output.
Blend Mode Choose how the image blends with the scene. See Blend Modes for details.
- Solid : The generator is solid, with a filled alpha channel.
- Blend : The generator RGBA values have matching alpha channels.
- Pre-Mul Blend : The RGB values are solid white, and the generator colours are stored in the alpha channel alpha. Usually gives the best results for colour blending.
