[Gambas-user] glu.buildmipmaps error

[piet at ...3034...]

Hi, 

I'm using opengl for 2D Projektion with textures. 

running
following code rises me an error: "Speicherzugriffsfehler(11)" (which
means sth. like memory-access-error) 

> Dim xx1, xx2 as Image 
> 
> Dim
textures as new Integer[2] 
> 
> gl.MatrixMode(gl.PROJECTION)
>
gl.LoadIdentity
> gl.Ortho(0, screen.Width, screen.Height, 0, 0, 1)
>
gl.MatrixMode(gl.MODELVIEW)
> gl.Disable(gl.DEPTH_TEST)
>
gl.Enable(gl.TEXTURE_2D) 
> 
> textures = gl.GenTextures(2) 
> 
> xx1 =
Image.Load("xx1.png")
> Gl.BindTexture(Gl.TEXTURE_2D, textures[0])
>
Glu.Build2DMipmaps(xx1) ' this is where the error appears 
> 
> xx2 =
Image.Load("xx2.png")
> gl.BindTexture(gl.TEXTURE_2D, textures[1])
>
Glu.Build2DMipmaps(xx2)
> 
> Gl.TexParameteri(Gl.TEXTURE_2D,
Gl.TEXTURE_MIN_FILTER, Gl.LINEAR_MIPMAP_NEAREST)
>
Gl.TexParameteri(Gl.TEXTURE_2D, Gl.TEXTURE_MAG_FILTER, Gl.LINEAR)

Thank
you v. m. for help,
