[Bf-committers] pixel get & image processing

[Daniel Salazar - 3Developer.com]

Very nice, You think is it better to access the image directly instead
of generic access to textures? that way we could get values from
procedurals too

cheers

> You can also use it for:
>  * make meshes from blue prints
>  * motion capture
>  * any other image processing you need
>
>
> PATH creates new properties:
>   bpy.types.Image.frame
>   bpy.types.Image.pix_x
>   bpy.types.Image.pix_y
>   bpy.types.Image.pixel_color (read only)
>
>
> Example usage:
>  bpy.data.images['video'].frame = 2       # set video frame to process
>  bpy.data.images['video'].pix_x = 5       # set x coordinate of pixel
>                                            # we want to access
>  bpy.data.images['video'].pix_y = 10      # set y coordinate of pixel
>                                            # we want to access
>  bpy.data.images['video'].pixel_color[0] # returns red channel (0-255)
>  bpy.data.images['video'].pixel_color[1] # returns green channel (0-255)
>  bpy.data.images['video'].pixel_color[2] # returns blue channel (0-255)
>  bpy.data.images['video'].pixel_color[3] # returns alpha channel (0-255)
>

> Any chances to put it into official release? I will publish 3D scanner
> add-on this year.
