Circle proceeded with anti-aliasingIf you would like to know more about the technique, please check here 「2Dグラフィックスのしくみ」 (wrote by FireAlpaca Developing Team). In graphic processing, anti-aliasing performs and revised as insufficient pixels information included.
Opacity depends on the coverage of its part.In this way, you can draw it perfectly by FireAlpaca. What if you adjust the opacity based on the area covered while you are drawing like this? Image. Or take this “covered in one quarter” pixel, set in 25% opacity opacity pixel. Is the only way to draw a circle in this way?Īs the former image, you might think that is difference between “fill” and “unfill”.įor example, take this “covered in half” pixel, set in 50% opacity pixel. You would like to draw a circle like this ( on the left side of examples below) at first, but you are not able to make the units more smaller. However, there is no other description other than using 1 pixel. See!! The circle is not as pretty as imagined right. On the SAME layer start drawing lines and they will only go in the circle. You pick Protect Alpha and decided that you want to put random lines on this circle. So let’s say you have a circle on layer one.
Seems like the circle shown below, right? Image. 1 What does protect Alpha do in FireAlpaca Answer Protect Alpha is kind of like a clipping mask for that layer. Let’s take this small image (20×20 pixel) for example. Therefore, there is no any other description except for pixel. The smallest unit of digital image is pixel.
