Gradient Tool preview

Recommended Posts

Just thought I'd share this. It's a short video I made showing the first draft of the gradient tool, which will be available in the upcoming Alpha 2 release.

Edit: My friend uploaded this to YouTube:

Its great how you can move the start and end nubs around.

Just out of interest, is it going to support more than 2 colors in the same gradient?

Rick, the way this project is headed, this will probably be one of the greatest image editing software out there! (And that includes Shareware)

EDIT: After the Download: Woah. That is more interactive than everything!

Nope, only 2 colors for 3.0.

NICE!

But, Rick, I didn't see "square" gradients, Alpha only, or HSV gradients. Are they included?

And, Alpha Only?

I'm thinkin', I'm thinkin' ...

Supporting alpha only is trivial to add for just this feature. But it's just a matter of generalization: none of the other tools support it! What I really want are layer and channel masks. But in the short term it may make sense to just add a toggle button or checkbox for the gradient tool.

If you don't want to support an "alpha only" option in this tool, I would highly recommend making a similar tool called the "Transparency Tool". It would have all the same functionality as the gradient tool, however it would always work with alpha only and always go from fully opaque to fully transparent.

CorelDraw has such a tool and it is incredibly useful.

Unfortunately then when I add in the real support for things like masks, and then remove the "Transparency Tool," everyone will e-mail or post on the forum asking "where is teh transparency tool gone to :cry: "

Perhaps its time to implement masks then.

A Transparancy Tool will always be incredibly useful, whether it affects alpha directly or it creates a control layer object. (Could it be coded one way now and converted to work the other way later?)

Believe me, people are not using the gradiant plugin to make colorful fades, they are using it to fade one picture to another, or fade something to transparent.

I'd have to say that it is a 50/50 split for me, But trying to "fade one picture to another, or fade something to transparent" is definitely important.

I want masks too, believe me. But also believe me when I say now is not the time to be working on the layering system. Of course the obvious response question is "why?"

Because right now is the time to finish up and stabilize the features that have already been implemented, namely MDI. It's an enormous change to the codebase and it needs time to "cook" before getting the next meal course ready, so to speak. (Unfortunately the cook/chef metaphor only goes so far)

Changes to the layering system are itching to go, but require a substantial rewrite of the Layers window UI and several other things in the code base.

But once that stuff is done, watch out.

Aww, my first "picture fade." I used two pictures from http://larenn.deviantart.com

Anyway there's your alpha-only option. The button to the right with the blue and salmon colored rectangles is just the alpha blending toggle redone with a new image and as a split button.

Are these icons hinting what I think they're hinting?? multiple colors in a gradient?

No, think of the first entry as an RGB Gradiant and the second as Alpha Only.

I get what you are saying. I was thinking the four boxes in each icon represented ability to use more than just the primary and secondary color for the gradient...which would be nice!
