Detecting terminal capabilities

Here is an example of a program that uses TermInfo.detect_capabilities() to figure out what the current terminal is capable of.

from chafa import *
from chafa.loader import Loader

# Init canvas config
config = CanvasConfig()

# Set canvas height and width
config.height = 30
config.width  = 30

# Init database and get terminal info
term_db   = TermDb()
term_info = term_db.detect()

# Get terminal capabilities
capabilities = term_info.detect_capabilities()

# Set config to appropriate modes
config.canvas_mode = capabilities.canvas_mode
config.pixel_mode  = capabilities.pixel_mode

# Open image with the loader
image = Loader("./snake.jpg")

width      = image.width
height     = image.height
rowstride  = image.rowstride

# Init the canvas
canvas = Canvas(config)

# Draw to canvas
canvas.draw_all_pixels(
    image.pixel_type,
    image.get_pixels(),
    width,
    height,
    rowstride
)

# Write picture
print(canvas.print().decode())
