Bug report: wrong error message

[twin-moon]

Minor bug:
When I imported a background into my 320x240, 256 colour game, AGS told me:

"The background could not be imported. The error was:
You cannot import a hi-colour or true-colour image into a 256-colour game."

But the error was that my resolution was wrong. I had me thinking I was crazy for a minute.

Can you post the image that you tried to import? That error should only appear in the circumstances that it describes.

[twin-moon]

It was this one

I've discovered some more:
When I use 320x240 with hi-colour it stretches the image out to 240. When I change back to 256 colours and import it again, it gives me the error message that I can't import hi-colour images in a 256 colour game.

Probably because it tries to stretch it out and stretching out requires hi-colour?

although that image does use less than 256 colours my guess is that it actually needs to be using an actual 256 colour palette otherwise AGS is just going to assume it's high colour and not 256 and give you that error.

Right, that image is actually a 24-bit true colour image. Remember when you import an image into a 8-bit game, it's that the image has to be saved as a 8-bit format, not just it uses less than 256 colours.

[twin-moon]

?? That's odd. I've uploaded a wrong pic. Here it is again.
It's definitely in 256 colour, if it isn't my hosting service did something to it.

I've checked again to make sure I didn't accidently try to use a hi-colour image in the editor, but it still gives me the wrong error message.

[Gilbert]

No, it's 24-bit, at least the one I downloaded is.

What programme did you use to save the PNG?

[Pumaman]

The first image you posted was 32-bit and wouldn't import into an 8-bit game for obvious reasons.

However the new one that you've uploaded is indeed 8-bit, and I am able to import it into an 8-bit game fine. Are you sure it's this image and not the previous one that was causing the error?

[twin-moon]

When I import the image in a 256 colour game with resolution 320x240 I get the error message "You cannot import a hi-colour or true-colour image into a 256-colour game."
It should say that the resolution is wrong, but not that the colour depth is wrong.

No, it's 24-bit, at least the one I downloaded is.
What programme did you use to save the PNG?

The first one was hi-colour, my mistake, but if you download it again it should be 256 colour.
I used Paint Shop Pro.

Thanks, I have now replicated the fault. Seems .net doesn't handle 8-bit images very well so I'll have to make some changes to get it fixed.

[Gilbert]

Odd, the last time I checked, the second link pointed also to a 24-bit image. It is 8-bit now, possible some kind of browser cache problem. I'm glad the problem is sorted out.

However, your first image was not hi-colour, it was true-colour.

[twin-moon]

However, your first image was not hi-colour, it was true-colour.

Yes, you're right. I tend to mix those up, which is of course wrong. (It's because in Paint Shop Pro there's only one 'mode' beyond 256 colour / 8 bit mode. You probably can distinguish between hi-colour and true-colour, but since I never use true-colour I never looked into it.)

Ok, good to know it's not just me   Thanks.
