First time poster here!
Just installed Inkscape last night, and am trying to use it to make components (e.g. Sprites, Buttons, Icons) for my website.
Unfortunately, I am not an Artist or Graphic Designer, and I've never used Graphic Software before, so this is all very intimidating!!
Right now I am trying to build a Sprite, and am struggling with there being a white background around my Icons when the surrounding area should be transparent?!
So, my first question is...
What is the difference between "Alpha" and "Opacity" and "Master Opacity"?
Sincerely,
Debbie
Alpha vs Opacity vs Master Opacity
Re: Alpha vs Opacity vs Master Opacity
Hi!
Alpha values are colour related.
With the rgba profile inkscape uses, you can add a value of 0-255 to any colour.
The opacity is an object related attribute that svg provides. You can set opacity by percent values to each object.
If you are unsure if you see a white filled rectangle -or a rectangle with white outlines- or the default wite background, then
open the document's properties panel (Shift+Ctrl+D) and change the transparent background colour to grey with no alpha values for example.
