ROPAP

Lilly H. St Claire

ROPAP is yet another opengl pixel mapper, this time written in Rust! It has a struct (which is named Renderer) which holds only private members, and the following public functions:

• pub fn new(resolution_x: u32, resolution_y: u32, window_width: u32, window_height: u32, title: &str) -> Renderer

This creates a new renderer whose window is of size window_widthxwindow_height and has a map resolution of resolution_xxresolution_y.

• pub fn is_closed(&mut self) -> bool

Returns whether or not the window of the referenced Renderer has been closed.

• pub fn update(&mut self)

Updates the current pixel map, as well as drawing the next frame.

• pub fn draw(&mut self)

Draws the current frame, used in update.

• pub fn destroy(&mut self)

Destroys the Renderer, should be called before exit

• pub fn put_pixel(&mut self, x: u32, y: u32, color: u32)

Writes a pixel with color color to the pixel map at coordinates (x, y)

• pub fn put_rect(&mut self, x: u32, y: u32, width: u32, height: u32, color: u32)

Writes a rectangle of pixels with color color to the pixel map, starting at the coodinates (x, y) and ending at coordinates (x+width, y+height), if x+width or y+height are above resolution_x and resolution_y they will be set to their respective maximum.
