Half And Half Fast – Blending faster and easier

Blending faster and easier

I’m making shorter manual videos to upload on YouTube. I decided to write blog posts along with the videos. In doing so, I’m going to post something that’s hard to deliver on video, such as the motivation behind the development of a function.

The video I’m going to produce this time is about the Half function of PAI. This feature had been used a lot to increase the level of light and shade in previous painting videos.


The Edge

I wanted to make the sharp edges drawn with Animate smoother. As we all know, Animate is usually used for animation of graphics with relatively simple color structures. So drawing a background in Animate will not be a common choice.

But I found out that some amazing graphics by were drawn in Animate(Flash).

Their works were incredibly astounding to believe they were drawn in Flash. So I decided that if Flash was enough, there was no reason not to do it.(I didn’t want to move around if Flash was enough.)

However, every time I had to trim the sharp edges that Flash created, it felt quite cumbersome.

This involves two or more changes in colors. In other words, it could be increasing the level of light and shade, or mixing two colors. Usually we use color picker tools to describe these color changes. Changes to a single color will be sufficient for the tool, but it’s going to be a little bit more complicated to express the change between two or more colors. Of course, there is no problem if we have nice eyeballing skills regarding color selection, but I didn’t have the ability to do that, so I even envied those who were good at it.

As we all know, flash’s brush does not support dynamic opacity changes by pen pressure, so we can use the following methods when we add levels of light and shade and choose the middle color.

Three common ways of mixing colors

1. Select each of the two colors to identify the position of H, S, and V on the color tool, and then select their midpoint.

2. Use linear gradation to select two colors for start and end point, and then select the desired midpoint.

3. After overlapping the shapes with different colors, adjust the opacity value to find the desired color.

If we have to do this over and over again, all of these methods will be quite tedious.

Half Command

This feature can be used to add levels of light and shade or to express a natural blend of two colors. It is a very simple function that finds the middle color of two colors and sets it to the color of Brush tool. It is implemented as a command, so you can assign a keyboard short cut and run it quickly.

Let's try it.

First, move the mouse cursor over the shape where the first color is located and run the Half command with the shortcut you assigned. The shape below the mouse cursor will be selected as shown below. You don’t need to click on the shape. Half command gets the color value of the shape below the current mouse cursor position. Like all other tools in PAI, it only supports solid color, so gradient color is not supported.

Now select the second color in the same way. Move the mouse cursor over the second shape and rerun the Half command with your shortcut.

When you execute the second half command, the following tasks are performed internally.

1. It sets the middle color of two colors to Fill color.

2. It changes the current tool to Brush tool.

As a result, you can resume painting using the Brush tool as soon as you get the middle color.

Half Fast Command

Now let’s use Half Fast this time. Half Fast is a command to find middle colors by fixing one color and selecting another. This reduces the behavior of performing a function by half compared to Half.

First, click the shape where the first color is located.

In the Half section of the HUD extension, click the Get In button.

The selected color must have been set in one of the 1, 2, 3 slots in the Half section of the HUD. Before you click the Get In button, you can select the slot where the color will be set by pressing one of the 1, 2, 3 buttons.

Now move your mouse cursor over a shape with a different color and run the half fast command in a short cut. Then try painting using the Brush tool.

In the upcoming video on the Half function, we will apply it to the actual painting work, not just the shape. It will be an interesting video that effectively controls sharp edges while maintaining the neatness of the vector graphics. If you are interested, please subscribe to our channel.

That’s it for this blog post. Happy painting!

I make software for vehicle during the day and draw pictures at night.

Note: While I was writing this post, I found that there was a bug in the Half Fast function and I modified it. When you run PAI extension, if you receive a pop-up to notify you of a new version, please download and reinstall the zxp file from the below link.
