Hi,
I'm currently trying to create solid image with just hight width parameters added.
I made pretty fast code which loops every pixel in image and sets its color, but it looks too much work.
For example in 2000x2000 image buffer.setRGBA(x, y, r, g, b, a); should be called 4 000 000 times..
Is there any smarter way to do this?

If the color has the same RGBA components, this is the easiest way of writing it:


The above produces a white, opaque texture. If you are looking for something more efficient and more flexible (i.e. specific colors), check out my changes to EmptyImageData here:

Some considerations:

• Slick uses power-of-two sizes for textures, so your 2000x2000 image will be stored as a 2048x2048 OpenGL texture.
• You might be pushing it with your texture size; if compatibility with older systems is important to you, it would be safer to use no greater than 1024x1024 textures
• If you plan to change the texture with getGraphics, don't bother creating a coloured texture -- see here
• Why do you need a solid texture anyways? And why does it need to be so large? Maybe there is a better way of doing whatever it is you're trying to do...

Thanks for the replay!
I'm aware of power of two rule, this is not my first lwjgl engine, I just used 2000x2000(it's image not texture size, i used it so i could easier multiply it) as an example.
The constructor new Image(int, int, Color) you described in your topic is pretty much all i needed.
The texture i want is screen width x height, i need this image to use it as my fade in, fade out, dim mechanism.
I need image because i have already created animation system, so with this image I could nicely fade in and out.
Yes there is probably better way, but I'm too lazy to implement it .
And no, compatibility with older systems is not important.

EDIT:
I have just figured out that all kind of transissions already exist in states.transition package
