This represents an area for drawing graphics. It has now been superceded to a large extent by the much more flexible Gdk::Drawable RGB functions. To create an image from part of a Gdk::Window use Gdk::Drawable::get_image().
The image can be manipulated with get_pixel() and put_pixel(), or alternatively by changing the actual pixel data, though manipulating the pixel data requires complicated code to cope with the different formats that may be used. To draw a Gdk::Image in a Gdk::Window or Gdk::Pixmap use Gdk::Drawable::draw_image().

virtual |
|
protected |
Instantiate a new Gdk::Image.
type | The type of the Gdk::Image. Gdk::IMAGE_FASTEST is probably the best choice, since it will try to create a Gdk::IMAGE_SHARED image first and if that fails it will then use Gdk::IMAGE_NORMAL. |
visual | The Gdk::Visual to use for the image. |
width | The width of the image in pixels. |
height | The height of the image in pixels. |

Glib::RefPtr<Colormap> Gdk::Image::get_colormap | ( | ) |
Retrieves the colormap for a given image, if it exists. An image will have a colormap if the drawable from which it was created has a colormap, or if a colormap was set explicitely with set_colormap().

GdkImage* Gdk::Image::gobj_copy | ( | ) |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

void Gdk::Image::set_colormap | ( | const Glib::RefPtr< Colormap > & | colormap | ) |
Sets the colormap for the image to the given colormap. Normally there's no need to use this function, images are created with the correct colormap if you get the image from a drawable. If you create the image from scratch, use the colormap of the drawable you intend to render the image to.
Deprecated: 2.22: Gdk::Image should not be used anymore.
colormap | A Gdk::Colormap. |

A Glib::wrap() method for this object.
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
