New, to pycairo, so maybe I'm missing something...
I'm trying to draw a simple polygon with move_to & line_to, however the values appearing in the SVG output are only accurate to the 100th place.
for example:
I give an x coordinate in the move_to call of 6.426575 but it shows up in the SVG file as 6.425781
for some reason its loosing precision after 6.42, the next digit should be a 6, but I'm getting a 5.
here's my code:
import cairo with cairo.SVGSurface("test_2.svg", 100, 100) as surface: context = cairo.Context(surface) context.set_line_width(.1) context.set_source_rgb(1, 0, 0) context.move_to(6.426575, 89.055378) context.line_to(65.205100, 3.311026) context.line_to(123.983626, 89.055378) context.close_path() context.stroke()
here is the svg output
<?xml version="1.0" encoding="UTF-8"?> <svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100" height="100" viewBox="0 0 100 100"> <path fill="none" stroke-width="0.1" stroke-linecap="butt" stroke-linejoin="miter" stroke="rgb(100%, 0%, 0%)" stroke-opacity="1" stroke-miterlimit="10" d="M 6.425781 89.054688 L 65.207031 3.3125 L 123.984375 89.054688 Z M 6.425781 89.054688 "/> </svg>
