Question 1

How do I show Olive.c graphics in a window?

Accepted Answer

You need to integrate a separate library like SDL to create a window and blit the pixel buffer. The demos provide examples using SDL for desktop and HTML5 canvas for WebAssembly, requiring additional setup.

Question 2

Olive.c or raylib for 2D graphics in C?

Accepted Answer

Olive.c is minimal and dependency-free, focusing only on pixel rendering, while raylib offers a full game development suite with windowing, input, and audio. Choose Olive.c for control and portability; raylib for feature-rich projects.

Question 3

Can Olive.c be used for game development?

Accepted Answer

It's suitable for simple 2D games or prototypes due to its basic primitives, but the lack of built-in input handling, animation support, and performance constraints for complex scenes make dedicated engines like SDL more practical.

Question 4

How to save Olive.c output as a PNG file?

Accepted Answer

Use an external library like stb_image_write.h, as shown in the flag example. Include it, define the implementation, and call functions to write the pixel buffer to a file after rendering.

Question 5

Does Olive.c support transparency and alpha blending?

Accepted Answer

Yes, through functions like olivec_blend_color, but you must initialize the canvas with a color that has non-zero alpha to avoid transparency issues, as warned in the README's example.

Question 6

What's the performance like for large resolutions?

Accepted Answer

Since it's software-based and renders pixel by pixel, performance can degrade with high resolutions or complex scenes, making it less ideal for real-time applications compared to hardware-accelerated alternatives.
