Introducing User Defined Brushes, and Gradient Color Animation.
In this video, the User Defined Brushes were used to draw the flowers and grass before Shadowed Strokes setting was turned on. You notice that the flowers/grass is rather dense. If you turn on the Shadowed Strokes before drawing with the User Defined Brushes, then the marks you make will be less dense, because drawing with shadows takes more time. But that may be exactly what you want: a texture that is less dense, and the ability to better control and see the individual marks with the help of the shadows.
Note that Gradient Colors work only with objects that are "filled" with color by TwoToJazz. For example the two-finger calligraphy brush used in this video to write the word Hello creates an object that is filled with color. The free-style brush used to draw the flower is another example. In contrast, there are brushes in TwoToJazz (like the one used to create the grass) that draw only lines that could be thin or think, but have no filled area. Line-based objects do change colors during color animation, but with no gradient effect. The brush on the bottom of the one-finger menu is also a simple line brush with no fill and thus does not show the gradient effect.
TwoToJazz version 1.5 introduces a brand new and exciting feature called User Defined Brushes. You can now define your own one-finger brushes! All it takes is drawing a simple object and adding it to the one-finger brush menu, from which you can then select any of your user defined brushes and draw with. You can use this feature to add texture to your drawings, and create a more painterly look, especially when used with Shadowed Strokes.
The image below is a screenshot of a TwoToJazz drawing in Animation Mode, with both "Shadowed Strokes", and "Animate Colors" settings turned on. The many different foliage and texture in this work were created using user-defined brushes.
The new user defined brushes are added to the existing "Advanced Edit and Animate Tools" In-App Purchase bundle. They are located on the right column of the one-finger brush menu.
To add a new user defined brush, or replace an old one, follow these steps:
(1) draw a simple object,
(2) select the object,
(3) open the one-finger brush menu and press +,
(4) tap on a user-defined brush you'd like to replace; the brush is now added to your brush menu and you can select it at any time and draw with it. You can control the size of the brush with the slider, and change its color and opacity as usual.
Please use this feature judiciously, as overuse of it in a given drawing can slow down edit/zoom/autosave actions that require redrawing of all of the objects at full resolution.
