You said you
enlarged an image, and didn't see a difference. There's only one way to interpret that. You can't just enlarge a low-res image to make it high-res. You have to use an image that's high-res to start with.
First off I wasn't referring to high or low resolution, only the fact that my skybox, being of low quality at 512x512 wasn't improved by resizing it with Infranview to 1024x1024. My second post stated that I would attempt a resize of another box of much higher quality to 2048x2048. I didn't get a chance to respond.
You only assumed I meant something I didn't particulate on so you were wrong, like I stated with your first
implication.
ZB, I didn't say a thing about resolution, don't put words in my mouth! :mad: Why don't you just crawl back into your Troll cave,and inspire instead of trying to degrade others for a change! It gets old having to explain something that someone else misconstrues. Don't be so quick to judge, for you are being judged!
Of course, the .png format would have to be high quality before any noticeable change would occur. You'd be better off saying nothing as saying something through your ignorance for a change. :mad:

Well, I'm confused. I don't know what you mean now. It seemed that ZB was making a valid response to your post (if a little tart in tone). And reading your response, it still seems that you don't understand how it works.
Enlarging a texture from 512x512 to 1024x1024 does make it higher resolution. The resolution you started with was 512x512, and the resolution you ended with is 1024x1024, which is "higher resolution". That said, you generally can't visually improve a texture just by taking it from low resolution to high resolution. The texture editor uses one of a number of possible algorithms to interpolate between the lower resolution pixels to generate intermediate higher resolution pixels to fill in the gaps when doubling (say) the number of pixels. But those interpolated pixels are just reasonable guesses as to what should be there. The end result is simply the lower resolution file scaled-up. It can't get better than that. The image is not the quality that you would have if you had started with a higher resolution source file. The only way to get a higher quality high resolution image is to throw away the low resolution one and start from scratch with a higher resolution original source file.
I believe that Sensut's point was that if you start with a high resolution image, the higher the better up to NewDark's limits, the better it will look. I don't think the intent was to imply that resizing a low resolution image to make it larger would do anything worthwhile visually. It won't.

Thanks for the info Larry, but you also misunderstand, that I already knew all of that, and was stating a simple fact. (yes, with no specifics) I know I didn't specify, but ZB has no buisness just speculating using only assumption, and above you is my post,and it is to the point. End of discussion!

Explain why you thought the quality would be improved.

I knew I must have misunderstood you, but, even after rereading your posts several times, I still don't understand what you are trying to do. It seems that you are trying to re-size (enlarge) a texture with IrfanView and expect a better quality result in-game from using such. That won't ever work. But you say end of discussion, so I will leave it there.

It's pointless to upscale a smaller image, the quality will not improve, but you don't need to downscale a large HQ image eroding the quality like in those old days :).

What's the "menu" you're talking about, Sensut?
The
game menu has this issue, namely use only the 640x480 corner of the large picture.

... that original has some horrible colour and banding artefacts for me, even in Irfanview: pink and yellow stuff all over, lots of sharp banding.
Ricebug on 15/12/2013 at 14:41
I'm not seeing any banding, but I do see the pink and yellow, though it's very faint on my end.
ZylonBane on 15/12/2013 at 15:15
Your skybox bitmaps have alpha transparency basically everywhere. Why? Why would you do that? Whyyyyyy??
Also the horrid yellow and purple color fringing that Watcher mentioned. That skybox seems basically unusable.
