A wild blog post appears!

^ Yeah, and it's an excellent introduction to löve shaders, thank you for posting it, Omar! Wherever you are.

One thing though, the method described in the post to create outlines does not work on images that have no spacing between the edge and the opaque pixels. An example:



With an image like this, there aren't any transparent areas, and therefore, the derivative between transparent and opaque pixels is 0 throughout the entire image. Is there a good workaround for this, other than just padding the image with transparency?

Hi, sorry, I never saw this question.

What you can always do is to take the derivative of the intensity, rather than the alpha (so, for example: col.r + col.g + col.b). In your case, however, this will be difficult: You could make the black parts glow by taking the derivative of 3-(col.r+col.g+col.b), but that would make the black inside the image glow as well.
So, no, I don't think there's a way in your case. You could create a second image and only pad that one with transparency, then make that glow and draw this image over it, if for some reason you need the image to be this exact size. But in this case, it migth be easier to just make the glow in gimp (unles you need it to change color and such, then I'd pad the image with transparency).

Can't open the irc because java blocks self-signed applications on my browser.. Anyway, would this be classified as a "high quality" post

I vote yes!

Sure thing; create an account, and post an application that says something along the lines of, "josefnpat sent me" and we'll get you rollin'.

Germanunkol and josefnpat, I'll be posting the application then, thank you

Ok, so in retrospect the blogs were way over engineered. I've greatly reduced pretty much all the hoops now.

Anyone who has writer status can now write, edit and delete their own posts without any review.

Go!

Could it be.. a new blog post?!

Why yes! This is a first step in trying to revive the blogs section. Too bad I didn't get a lot more replies on the tweets, but it's a start.

So to try get keep the blog active I decided to start interviewing developers.
Starting with rude!
