Creation methods:

• public Image ()
  Creates a new Image object.

Methods:

• public void animate_scale_mode (ulong mode, uint duration, ImageScaleMode scale_mode)
  Sets the value of scale_mode to scale_mode and animates the scale factor of the image between the previous value and the new value.
• public void clear ()
  Clear the current image and set a blank, transparent image.
• public bool get_allow_upscale ()
  Determines whether image up-scaling is allowed.
• public float get_image_rotation ()
  Get the value of the MxImage:image-rotation property.
• public bool get_load_async ()
  Determines whether asynchronous image loading is in use.
• public uint get_scale_height_threshold ()
  Retrieves the height scaling threshold.
• public ImageScaleMode get_scale_mode ()
  Get the current scale mode of MxImage.
• public uint get_scale_width_threshold ()
  Retrieves the width scaling threshold.
• public uint get_transition_duration ()
  Get the value of the MxImage:transition-duration property.
• public void set_allow_upscale (bool allow)
  Sets whether up-scaling of images is allowed.
• public bool set_from_buffer (owned uint8[] buffer, DestroyNotify? buffer_free_func) throws Error
  Set the image data from unencoded image data, stored in memory.
• public bool set_from_buffer_at_size (owned uint8[] buffer, DestroyNotify? buffer_free_func, int width, int height) throws Error
  Set the image data from unencoded image data, stored in memory, and scales it while loading.
• public bool set_from_cogl_texture (Handle texture)
  Sets the contents of the image from the given Cogl texture.
• public bool set_from_data (uint8[] data, PixelFormat pixel_format, int width, int height, int rowstride) throws Error
  Set the image data from a buffer.
• public bool set_from_file (string filename) throws Error
  Set the image data from an image file.
• public bool set_from_file_at_size (string filename, int width, int height) throws Error
  Set the image data from an image file, and scale the image during loading.
• public void set_image_rotation (float rotation)
  Set the MxImage:image-rotation property.
• public void set_load_async (bool load_async)
  Sets whether to load images asynchronously.
• public void set_scale_height_threshold (uint pixels)
  Sets the threshold used to determine whether to scale the height of the image.
• public void set_scale_mode (ImageScaleMode mode)
  Set the scale mode on MxImage
• public void set_scale_width_threshold (uint pixels)
  Sets the threshold used to determine whether to scale the width of the image.
• public void set_transition_duration (uint duration)
  Set the MxImage:transition-duration property.

Signals:

• public virtual signal void image_load_error (Error error)
  Emitted when an asynchronous image load has encountered an error and cannot load the requested image.
• public virtual signal void image_loaded ()
  Emitted when an asynchronous image load has completed successfully
