common vs simple

[KaelanRichards]

I am trying to implement a photoshop brush experience in the browser. This seems like a great tool. I am having trouble getting the hang of how to use this library. I would like to have similar data control like the common example. Maybe a bit more documentation would help.

what is the difference between the simple and common examples?

Thanks for creating this!

The common brush and the simple brush have a similar interface, and the difference between the two brushes is the way they draw.

The common brush draws by calling ctx.drawImage multiple times from the start point to the end point, whereas the simple brush draws lines using the canvas vector drawing function.

So, what can be expressed with a common brush may be difficult to express with a simple brush.

So, if I were to want photoshop like features such as flow, opacity on pen pressure, etc. I would use common brush?

[disjukr]

Right. Using common brush only is enough.

Thanks!

Is there a way to implement undo with common brush? Seems tough since it continuously draws the image

In the old version(https://github.com/disjukr/croquis.js/tree/v0.3.2), croquis.js supported a bit more scope such as layers and history functions, but now only brush implementation is left.
