Okay, so I'm trying to use the canvas to draw a trapezoid. Here's my code. For some reason it just creates an empty box.

# coding: utf-8
import canvas
b = 10
canvas.set_size(500, 500 + b)
canvas.draw_rect(0, 0 + b, 500, 500)
canvas.set_fill_color(1, 0.1, 0.1)
canvas.set_stroke_color(1, 0, 0)
canvas.set_line_width(4)
canvas.begin_path()
canvas.add_line(150, 100 + b)
canvas.add_line(350, 100 + b)
canvas.add_line(400, 200 + b)
canvas.add_line(100, 200 + b)
canvas.add_line(150, 100 + b)
canvas.draw_path()
canvas.fill_path()
canvas.close_path()

I did what you said but I'm still getting the "Image Not Found" Error

It's not in a sub folder. I have no idea why it's not working.

@omz Does the folder have to have the same name as the program?

Yes it is

That solves the issue with the blue gem not appearing, but if I use one of my own images that I imported into the folder

self.spriteName.texture = Texture('IMG_0469.JPG')

returns a "Image not found" error and

self.spriteName.texture = Texture(ui.Image.named('IMG_0469.JPG'))

returns a "Could not load image" error

Okay now there's no error, but I can't see the sprite when the code compiles.
Here's my setup method

        def setup(self):
                self.background_color = 'green'

                self.spriteName = SpriteNode()


                self.spriteName.anchor_point = (5,5)
                self.spriteName.position = (50, 50)

                self.spriteName.texture = Texture('plc:Gem_Blue')

Now it says "global name 'scene' is not defined"

@omz Whenever I try that, I get an error that says "Expected a texture object".

I have a sprite called spriteName. Whenever I type something like.

self.spriteName.texture = ('plc:Gem_Blue')

or import my own image into my own folder called Textures and use

self.spriteName.texture = ('Textures/IMG_0469.JPG')

They both result in the error "TypeError: Expected a Texture Object"
I don't know what I'm doing wrong.
