What is Picture to People ?

"Picture to People" (P2P) is a huge Computer Graphics project. It was started to create new softwares able to make 2D drawing, 3D rendering, vexel drawing, text effects, photo effects, image filtering and other complex Computer Graphics operations. It has been made from scratch, including its low level Computer Graphics libraries like Maccala. Nowadays, most final features produced for this project are released as free online tools available from its official website. This blog talks about Computer Graphics, mainly concerning Picture to People development.

More advanced arrow drawing styles and configuration

Since I released my vector based drawing library for the first time and started using it, there was many ways to draw arrows, because it already had very customizable methods to make it. You can even see a screenshot about it at the web page about Maccala's features.

Anyway, the library had some limitations, as for example: just straight arrows could be drawn and only using a chosen but fixed thickness for arrow body.

I have recently created more methods in my class responsible for drawing 2D vector based objects in a canvas, including methods to draw more configurable and generic arrows. Summing up the old and the new features, now arrow drawing tasks can take advantage of these main features:

- ability to draw straight or curved arrows;
- use of arbitrarily progressive arrow body thickness;
- use of highly configurable arrow head shape;
- ability to draw arrow head in both sides if desired;
- use of any RGB color;
- use of configurable high level anti-aliasing.

Below you see some examples of arrows created by using the new features I have developed.
