Help making a checkerboard

[rich2005]

Quote:I want 13cm cubes wide by 11cm cubes tall... So 143 cubes total? The GEGL operation thing doesn't make sense when trying to input centimetres.

The GEGL checker works in pixels, so get your calculator out or let Gimp do the arithmetic for you.

Make a new canvas and start off the way you mean to continue.
You want 300 ppi (usually for printing purposes) so set that first.
Now set units to cm and the size to 13 x 11. Note Gimp work in pixels there is a tiny rounding error in the conversion. You end up with a canvas size in pixels 1535 x 1299 pix.



Do not OK that. Go back to the pixels/in drop down and change that to pixels/cm



Remember the value shown, 118 pixel/cm Now you can ok that and create a new blank canvas.

Into the GEGL checkerboard dialog. All you need do is set the Width and Height values to that 118 pix (= 1 cm)
