Dooglus: tell Genete about units

tell Genete about units

New page

Genete, you wrote: "Feather is a float value in points"... Well, feather is just a float value. It's not really in points or centimeters, or any other unit. It's just a measure of length. There should be a page about the units Synfig uses somewhere, but for now I'll just write this:

In the main Synfig window, go to "File > Setup > Misc > Unit System" and you will see that you can tell Synfig that you want it to work in Units, Pixels, Points, Inches, Meters, Centimeters, or Millimeters.

The conversions between these things are as follows:

1 inch is 72 points or 2.54 centimeters
1 metre is 100 centimeters or 1000 millimeters
1 unit is 60 pixels

points, inches, meters, centimeters and millimeters are all real units of measurement, fixed relative to each other, but I've said nothing about how to convert from them to units and pixels. That's because the conversion factor depends on the canvas' Physical Width and Physical Height.

If you look at a workarea's properties (caret > edit > properties) then in the 'image' tab, under 'image size', you'll see these two. Physical Width (in inches) is Width (in pixels) divided by XRes (in pixels per inch). If you modify width or XRes, Physical Width will automatically be updated. If you modify Physical Width, Width will automatically be updated.

If you leave these at their default settings, then 1 pixel is 1 point. If you change them then I don't really understand what happens - all your parameters will change, unless you're working in units or pixels, both of which seem to be the 'stable' or 'base' units.

		+	: You're right about the first paragraph. I'll write: "Feather is a float value" ... OK. Then I should also correct this one: "When you apply a Feather to any of those layers, then the edge of the shape becomes dissolved and spread out and shrunk the amount ''of points'' that the Feather value indicates". I should remove "of points". BTW, would you add or correct something to this page?. Please tell me to correct the style or description structure if doesn't meet your standards.--[[User:Genete\|Genete]] 01:11, 14 Sep 2007 (EDT)
