i did not stretch the image
i did not do anything but

load image "myimage.bmp",1,0

paste image 1,0,0,0

and on windows vista you get these crappy lines that appear
xp visual is fine....xp works perfect.....whats going on?

No need to keep bumping the thread, It's 10 mins old and is still really near the top

Well, Does this happen with all images? Does this exact image work fine on XP?

Did you try load image "myimage.bmp",1,0 ?

I also have Vista, and I've never had such a weird effect. Could you post that image, so that I can have a look to see if it also distorts when loading it in DBPro?

Cheers

What display mode are you using ? Windowed Full screen or Full Screen Exclusive ?

If you're using full screen window, the DBpro will stretch the screen to the display the desktop resolution.

Well, then there must be something with the settings of your graphicscard, or maybe you have'nt the latest drivers or directx version, 'cuz it ran fine on my machine.

You are stretching the image. You set the screen size as follows:

But the image size is 800x400, so it WILL become distorted.

@Mobiius:

He is not stretching it. He just positioned it lower to get it centered (see screenie). His code ran fine on my machine, so there must be another problem causing the distortion of the image. It's probably some settings on the properties-panel of his graphicscard, or maybe his card has some issues with Vista, or he does'nt have the latest video-drivers for his card.
Edit: I think his AA or vsync are'nt turned on.

Vista came with DX10. DX10 has some of the DX9 stuff in it. Are you sure you have the latest DX9.0c SDK?

The fastest code is the code never written.

What do you mean by that? I have Vista, and it runs fine on mine.

You also said that it runs fine on your XP machine, but not on your Vista, so do both your machines have the same graphicscards?

ok so link 102... it looks like you got scan lines correct? and David yours looks perfect.


I am starting to think this is a problem with my pc's graphics card....and if thats the case i can still use it and ignore that im getting scanlines cause it should look fine on someone elses pc.

Any body with vista... do you mind giving this program a shot to see if you get scan lines.

From the DBPro Help file for LOAD IMAGE

Quote: "A Texture Flag of zero will treat the image as a texture and load to fill a texture surface in memory. A value of one will preserve the image without adding mipmaps, scaling or filtering and so retaining its pixel perfect quality."


You have been using

LOAD IMAGE "myimage.bmp", 1, 0

which allows mipmaps, scaling and filtering.

Have you tried changing the texture flag to a 1?

Well, you saw mine already, and it ran fine.

My guess is that it has nothing to do with your graphicscard, or which OS it runs on. I think it has something to do with the settings of your graphicscard. Is the AA or VSYNC set to ON? Which filtering does your card use to refresh the screen?
You should post the propertiespanel-settings of your graphicscard to see if everything is set correctly.

I think the problem is that some graphics cards don't like non-square textures, so loading the image as a texture on that machine will cause it to be rescaled. So...

It's probably because the texture size is not a power of 2. (The texture not being square could be an issue too, like Benjamin said)

I'd check the results of NONPOWTEXTURES AVAILABLE() on both computers. My graphics card does not support non power of 2 textures, and displays the image incorrectly.

[EDIT]
It does support non square textures though.

Reduce the code to as little as you can: load the image, display it, wait for a keypress.

If it shows the problem then the problem is with drivers or DBPro. If it doesn't, then the problem is with one of the plug-ins you are using (possibly including other built-in ones).

If the problem doesn't appear with the cut-down code, then my initial guess would be that Blue GUI is the problem, particularly that 'resetMainWindow' command.

Do you have the latest drivers for your videocard installed (ATI Catalyst Control Center) ?

And did you try out all the different settings for your videocard (properties) ?

Maybe you could google the name of your graphicscard to see if there have been simular problems with that type of card?

Cheers
