I'm using the program hq3x to enlarge a bitmap that I've drawn. Now don't get me wrong it's a great little program but for some reason it doesn't blend all colours. Here's an example of what I mean:
As you can see the top two squares do not blend properly together whilst the bottom two do.
If you're familiar with what I'm talking about please help. I'm trying to figure out why they are not properly blending and what I can do to fix it. I got the program from here:
oh. try benvista photozoom pro 2. it's not free so you can't export the images, but you can grab the screen and import it into paintshop pro or something else to save, and its very good - not just for photos despit what it says.
I tried the program sketcy, it's probably not as sharp/accurate as hq3x and it still has the same problem. I'm starting to think that maybe it's impossible to blend similar colours because there just isn't enough middle colours to blend them with. That might be the answer. But it just can't be...
I believe it's because the way hq3x works.
The top 2 images are less contrasted by hq3x and the bottom 2 are more contrasted.
Read the first paragraph of the algorithm explanation.
P.s. Today I wrote my own resizing algorithm based on Scale2x (but it's much better! ).
I will implement it into an extension as soon as I can.
Because it's the same one but it changeable parameters and optional anti aliasing.
It can also fit (With the right parameters) to non-pixelart images such as more detailed pixelart, computer graphics ("Photoshoped"), and real photos.
