NAME

Clutter::Cogl::Texture - Low-level image handling

DESCRIPTION

COGL allows creating and manipulating GL textures using a uniform API that tries to hide all the various complexities of creating, loading and manipulating textures.

METHODS

handle = Clutter::Cogl::Texture->new_from_data ($width, $height, $flags=COGL_TEXTURE_NONE, $format=COGL_PIXEL_FORMAT_ANY, $internal_format=COGL_PIXEL_FORMAT_ANY, $rowstride, $data)

•
$width (integer)
•
$height (integer)
•
$flags (Clutter::Cogl::TextureFlags)
•
$format (Clutter::Cogl::PixelFormat)
•
$internal_format (Clutter::Cogl::PixelFormat)
•
$rowstride (integer)
•
$data (scalar)

handle = Clutter::Cogl::Texture->new_from_file ($filename, $flags, $internal_format)

•
$filename (string)
•
$flags (Clutter::Cogl::TextureFlags)
•
$internal_format (Clutter::Cogl::PixelFormat)

May croak with a Glib::Error in $@ on failure.

handle = Clutter::Cogl::Texture->new_from_foreign ($gl_handle, $gl_target, $width, $height, $x_pot_waste, $y_pot_waste, $format=COGL_PIXEL_FORMAT_ANY)

•
$gl_handle (integer)
•
$gl_target (integer)
•
$width (integer)
•
$height (integer)
•
$x_pot_waste (integer)
•
$y_pot_waste (integer)
•
$format (Clutter::Cogl::PixelFormat)

handle = Clutter::Cogl::Texture->new_with_size ($width, $height, $flags=COGL_TEXTURE_NONE, $internal_format=COGL_PIXEL_FORMAT_ANY)

•
$width (integer)
•
$height (integer)
•
$flags (Clutter::Cogl::TextureFlags)
•
$internal_format (Clutter::Cogl::PixelFormat)

pixelformat = $handle->get_format

(gl_handle, gl_target) = $handle->get_gl_texture

integer = $handle->get_height

boolean = $handle->is_sliced

integer = $handle->get_max_waste

integer = $handle->get_rowstride

integer = $handle->get_width
