The connections Profiles
A Profile Editor option is also available in the connection menu. Once selected, it opens a new window with a profile curve.
This profile curve allows you to adjust the interaction between the parameters (size, power, opacity, ...) and the connection you have just chosen (fade, pressure, random, ...)
A lot of profile curves are then available. For instance, the airbrush tool has 4 parameters which can use up to 10 connections. There are then 4 x 10 = 40 potential profile curves.
The applications of the profile curves are numerous, and we will only study here the most important examples.
Size and Pressure
If you connect the stylus Pressure to the Power of the Pencil tool, the more you push down on the tablet with the stylus, the thicker your line will be. In the example below on the left, the size of your tool will be bounded between 0 pixels and 30 pixels. (In this example, we want to focus on the size parameter behavior, so we will choose connection = none for the power parameter.)
Now if we change the profile curve as shown below on the right, the minimal size value for your tool will be 15 pixels.
Size and Fade
Let's admit that we draw a straight line on the current picture, from right to left with the oilbrush tool. If the profile curve stays unchanged, the line thickness is smaller and smaller.
The horizontal axis of the Connection profile panel shows the chosen connection from the maximal value to the minimal value.
The vertical axis of the Connection profile panel shows the values of the Size parameter.
As a consequence, if we change the profile curve as shown below, you will obtain the following results :
Angle and Random
Let's admit that you are using an animbrush with four images in order to add some colored flags on a picture. (see below, the handle of the animbrush is on the red cross or red line and the anim behavior is set to Random)
1234Handle
Here is the result if you draw a straight line with the settings opposite : (Don't hesitate to modify the Step parameter if you need to change the distance between the flags)
If we choose an angle of 90°, the result is monotonous ...
If we connect the animbrush Angle parameter to Random, the flags will be arranged in every directions. It is completely disordered.
Now let's modify the profile curve as shown hereafter :
The angle of the animbrush will be randomly chosen between 80° and 100° compared to the horizontal axis. The general aspect will be less monotonous.
(each gradation represents 90°)
The minimal and maximal angular values on the vertical axis of the profile curve are the same as the one you have chosen in the tool panel of the current custom brush.
For instance, if you select an angle of -50°, the gradations will then be :
Size and Random
We will now continue to work on the same example :
The purpose is now to make all the flags have a different size.
Of course, we can connect the Size parameter of the brush to Random.
Nevertheless a problem persist : we can have too small flags.
To remedy this, we only have to select a minimal size for our animbrush in the profile connection window.
Opposite and below, some randomly selected values between 75% and 100% of the original size will be used.
