Draw to a texture

[Ferret]

How do i draw to a texture?

 

This is what i'm trying to do, window.Image is TTexture

window.Image = CreateTexture(window.Width,window.Height)
SetBuffer(window.Image)

Then i want to draw a rect to it.

What happens when you DrawRect();?

[Ferret]

I get an error when i try to set the buffer saying that its not a TBuffer.

[DaDonik]

Well a TTexture simply is not a TBuffer.

 

what about: DrawImage

[ParaToxic]

Have you tried to create a TBuffer and set with SetBufferColor (or SetColorBuffer actually i don't know) and set Buffer?

[Ferret]

What i want to do is create an image from scratch and draw on it.

I also want to redraw the image when needed.

 

Pseudo code:

CreateImage()

SetBuffer(Image)

DrawRect()

SetBuffer(BackBuffer)

DrawImage()

 

How do i do this in LE, any examples floating around?

[Ferret]

Got it to work

 

I created a buffer and linked a texture to it using SetColorBuffer, like ParaToxic said.

This is the result, wip.

But have another problem with the text when i draw it to a texture.

You need to flip by Y

 

DrawImage(texture, 0 , Y , X , -Y )

The y coordinate gets flipped when you draw to a buffer. This has to do with the way the underlying graphics API works. In Leadwerks3D, the engine will detect these cases and correct them automatically, but for Leadwerks Engine do this:

DrawImage x,y+height,width,-height

Got it, thx!
