General Discussion / Scaler for pixel art
« on: April 05, 2013, 01:33:18 pm »
On the Allegro programming forums, user Siegelord made a pixel shader for upscaling pixel art.
It's nothing like all the interpolating algorithms (eagle, 2xsai, hq3x..), on the contrary it's something so simple that I'm surprised nobody did it before.
To quote user Pkrcel, "You are basicaly interpolating only at the "borders" of the scaled pixel ".
It's designed for up-scaling at arbitrary sizes, for example to resize a low-res game's window without being constrained to specific factors.
Thought this could interest some pixel-friendly coders here. Siegelord's test program is made with Allegro 5, but the shaders themselves are in glsl and hlsl - and their source is public domain.

General Discussion / Grafx2 2.3
« on: April 20, 2011, 11:25:53 pm »
Grafx2 v2.3 is out ;D. It's the first "official release" since 2.2 from one year ago.
There are no groundbreaking changes, but a large number of small improvements. The Palette screen for example is redesigned and makes it very easy to see duplicate colors and eradicate them. Changelog is here.
There are also some serious bugs fixed, so if there are people still using 2.2, they really should upgrade  :P

Any feedback is 100% welcome (bug reports are even 200% welcome)

A working Mac OSX version is also there. It was made by hhhikr a few weeks early before finalizing 2.3 so it lacks the very last touches of polish, but it's very stable.

By the way I've started a Grafx2 blog, because updating the website itself is a bit painful and nobody likes reading a manual. Grafx2 has a lot "under the hood" that's not evident at first glance, hopefully some highly-illustrated posts will catch people's interested and make them see beyond the pencil tool and the 1-pixel brush.
