The toGrayscale() method is used to convert any type of the specified color representation to it’s grayscale representation.
Syntax:
toGrayscale()
Parameters: This method does not accept any parameter.
Return Value: This method returns color representation in grayscale representation.
Example 1:
HTML
<!DOCTYPE html> <html> <head> <!-- Adding the FabricJS library --> <script src= </script> </head> <body> <script type= "text/javascript" > // Calling the toGrayscale() function over // the specified color values console.log( new fabric.Color( "hsl(0, 100%, 50%)" ) .toGrayscale()); console.log( new fabric.Color( "hsla(10, 40%, 53%, 0.6)" ) .toGrayscale()); </script> </body> </html> |
Output:
{"_source":[77,77,77,1]} {"_source":[125,125,125,0.6]}
Example 2:
HTML
<!DOCTYPE html> <html> <head> <!-- Adding the FabricJS library --> <script src= </script> </head> <body> <script type= "text/javascript" > // Initializing some color values in different color format var A = "hex(fff00f)" ; var B = "hsl(12, 13%, 25%)" ; var C = "hsla(10, 40%, 13%, 0.6)" ; var D = "rgb(10, 40, 13)" ; // Calling the toGrayscale() function over // the above specified color values console.log( new fabric.Color(A).toGrayscale()); console.log( new fabric.Color(B).toGrayscale()); console.log( new fabric.Color(C).toGrayscale()); console.log( new fabric.Color(D).toGrayscale()); </script> </body> </html> |
Output:
{"_source":[0,0,0,1]} {"_source":[62,62,62,1]} {"_source":[30,30,30,0.6]} {"_source":[28,28,28,1]}
