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]}
