The qrDecompose() method is used to decompose the specified standard 2×3 matrix into transform components
Syntax:
qrDecompose( mat )
Parameters: This method accepts a parameter as mentioned above and described below:
- mat: This parameter holds the specified array of transform matrix.
Return Value: This method returns the components of transform.
Example 1:
Javascript
<!DOCTYPE html> <html> <head> <!-- Adding the FabricJS library --> <script src= </script> </head> <body> <script type= "text/javascript" > // Calling qrDecompose() function over // the specified array of transform matrix console.log(fabric.util .qrDecompose([1, 2, 3, 4, 5, 6])); </script> </body> </html> |
Output:
{"angle":63.434948822922,"scaleX":2.23606797749979,"scaleY":-0.8944271909999159, "skewX":65.55604521958347,"skewY":0,"translateX":5,"translateY":6}
Example 2:
Javascript
<!DOCTYPE html> <html> <head> <!-- Adding the FabricJS library --> <script src= </script> </head> <body> <script type= "text/javascript" > // Specifying some array of transform matrix var a1 = [1, 2, 3]; var a2 = [0, 6, 7, 8, 0, 0]; // Calling qrDecompose() function over the // above specified array of transform matrix console.log(fabric.util.qrDecompose(a1)); console.log(fabric.util.qrDecompose(a2)); </script> </body> </html> |
Output:
{"angle":63.434948822922,"scaleX":2.23606797749979,"scaleY":null,"skewX":null,"skewY":0} {"angle":90,"scaleX":6,"scaleY":-7,"skewX":53.13010235415598,"skewY":0, "translateX":0,"translateY":0}
