Clutter::Cogl::Texture(3) 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 [email protected] 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
