How to added imbedded file[edit]

Anyone tell me how to add a graphics file as example? The embedded file widget just gives an example. It doesn't seem to give me a way to upload the file.

Thanks, --Dgamey 01:32, 6 May 2011 (UTC)

You can't upload here? This link is in the bottom of the sidebar -- "Upload file". --Mwn3d 01:52, 6 May 2011 (UTC)
Thanks - I have to learn to scroll down :) --Dgamey 12:00, 6 May 2011 (UTC)
I can't find the "upload file" link in the sidebar. -- Gerard Schildberger (talk) 21:57, 28 August 2013 (UTC)

Additional requirements[edit]

Take a parameter N for order (by command line is fine)
Calculate canvas size to allow for N (up to a limit)

What's all this talk about canvas size for N? What's N got to do with how big the triangle is? --Ledrug 03:31, 5 July 2011 (UTC)
First guess: So that no anti-aliasing or sub-pixel considerations are required to draw the image, so that representing the image using a 1-bit palette makes sense, and so such things don't cause an "oversaturation" of the resulting image such that you end up with a large, solid Triforce image. --Michael Mol 15:44, 5 July 2011 (UTC)
If the task has that in mind, it's going to be quite limiting: for pretty much all vector drawing languages/libraries, these are automatically handled when rasterizing, so it's redundant to link N to image size. Maybe it should be clarified a little. --Ledrug 21:43, 5 July 2011 (UTC)
Strictly speaking only Unicon and TCL speak of canvas size. The task just says order N. --Dgamey 01:34, 6 July 2011 (UTC)

Order[edit]

I didn't see a reference or anything in the WP article about what order N is. N appears to be the number of times the triangle is subdivided giving 2^N triangles per side. Seems obvious to me but it may not be to others.
