Image Overlay ? #13

Closed MentalGear closed 4 years ago

MentalGear commented 9 years ago

Hey, great (and fast!) Library! I found this as most modern js image processing libraries are quite outdated, yours could be one of the best around if you gave it an update. :) Also, using .png images as an overlay would be great as a new feature.

What sort of update? As far as I know, the library still works in all current browsers.

Adding "stickers" on top of images is way out of scope for this library - and easily solved without a library anyway. Just render the filtered image into a 2d canvas and draw the image on top.

Would be nice to have this rendered in WebGL, too. With the possibility to use some Photoshop Layer Blend modes.

Most(?) of these blend modes are now supported in Canvas2D as well.

I think this issue can be closed? Sounds like the library author has marked this out scope.
