SVG feColorMatrix Element
 Complete SVG Reference
Definition and Usage
The SVG feColorMatrix element is used to apply a matrix transformation.
The type attribute defines the type of matrix operation. The type attribute can
take one of the following values:
- matrix
- saturate
- hueRotate
- luminanceToAlpha
The value attribute's value depends on the value of the type attribute:
- For type="matrix", values is a list of 20 matrix values
- For type="saturate", values is a single real number value (0 to 1)
- For type="hueRotate", values is a single one real number value (degrees)
- For type="luminanceToAlpha", values is not applicable
Example 1
The following example shows examples of the four types of feColorMatrix
operations.
Copy the following code into Notepad and save
