The sprite tool for creating 2x sized sprites with HMOVE shifting is ready.
http://www.spiceware...ri/vector2x.php

To use it, enter a GIF image that's available online via URL

Tell it which color is the background color, color numbers are in the top-right, and an image using those numbers is at the bottom. (Tip: click CHANGE COLORS if screen color conflicts with any sprite color) Pairs of pixels are grouped inside of braces {} to show how it'll convert 2 pixels in the image into as single pixel in the sprite. Some lines start with a half pixel 1} which is valid for shifting a 2x sprite left/right at 1 pixel resolution.

And get the results (it spans more than 1 screen, so I just copied the text here).

It also does some validation of the 2x pixels and will point out problems.

I've company coming for this year's Art Car Parade (the blog entries from prior years) so I don't think there to be any more updates this week as I'll be busy cleaning house over the next few days.
