Hi,
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:

Image

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:

Thanks.

how do you even run it?

anyways, ask the people who made the program, as they should know (or will want to know if it's a bug)

I've tried the guy that made it but he doesn't reply from the emails.

You run it in Dos. Eg:

C:\HQ3X>hq3x.exe picture.bmp picturebig.bmp [Enter]

...and that's how you do it.

But yeah, a guy made it into a click program once. But still it doesn't fix the problem.

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...

A simple solution could be that you have a grey one resized, then change the colour properties of that to match green/back/whatever shades. Kinda weird how it does this, though.

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.

Does your program fix the problem? Please say it does. Please, please.

In my program the contrast threshold is variable, means you can change it to fit your picture.

Til then, you could possibly try splitting your image into 3 - the red channel, green channel and blue channel.

However, you decide that red works best with HQ3x. So you make all the channels show up as red.

Process them in HQ3X, then u'd need a little app to combine them again.

Some apps like PaintShopPro have the ability to split and combine RGB images.

Or use Scale2x. It's lower quality, but it doesn't have this problem.
Also my algorithm is based on it, but mine is better!

Stop bragging and tell us why it would be better.

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.
