gdk_image_new ()

GdkImage *
gdk_image_new (GdkImageType type,
               GdkVisual *visual,
               gint width,
               gint height);

gdk_image_new_bitmap ()

GdkImage *
gdk_image_new_bitmap (GdkVisual *visual,
                      gpointer data,
                      gint width,
                      gint height);

Creates a new GdkImage with a depth of 1 from the given data.

gdk_image_get ()

GdkImage *
gdk_image_get (GdkDrawable *drawable,
               gint x,
               gint y,
               gint width,
               gint height);

This is a deprecated wrapper for gdk_drawable_get_image(); gdk_drawable_get_image() should be used instead. Or even better: in most cases gdk_pixbuf_get_from_drawable() is the most convenient choice.

gdk_image_ref ()

GdkImage *
gdk_image_ref (GdkImage *image);

Deprecated function; use g_object_ref() instead.

gdk_image_unref ()

void
gdk_image_unref (GdkImage *image);

Deprecated function; use g_object_unref() instead.

gdk_image_get_colormap ()

GdkColormap *
gdk_image_get_colormap (GdkImage *image);

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 gdk_image_set_colormap().

gdk_image_set_colormap ()

void
gdk_image_set_colormap (GdkImage *image,
                        GdkColormap *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.

gdk_image_get_bits_per_pixel ()

guint16
gdk_image_get_bits_per_pixel (GdkImage *image);

Determines the number of bits per pixel of the image.

Since: 2.22

gdk_image_get_bytes_per_pixel ()

guint16
gdk_image_get_bytes_per_pixel (GdkImage *image);

Determines the number of bytes per pixel of the image.

Since: 2.22

gdk_image_get_bytes_per_line ()

guint16
gdk_image_get_bytes_per_line (GdkImage *image);

Determines the number of bytes per line of the image.

Since: 2.22

gdk_image_get_byte_order ()

GdkByteOrder
gdk_image_get_byte_order (GdkImage *image);

Determines the byte order of the image.

Since: 2.22

gdk_image_get_depth ()

guint16
gdk_image_get_depth (GdkImage *image);

Determines the depth of the image.

Since: 2.22

gdk_image_get_height ()

gint
gdk_image_get_height (GdkImage *image);

Determines the height of the image.

Since: 2.22

gdk_image_get_image_type ()

GdkImageType
gdk_image_get_image_type (GdkImage *image);

Determines the type of a given image.

Since: 2.22

gdk_image_get_visual ()

GdkVisual *
gdk_image_get_visual (GdkImage *image);

Determines the visual that was used to create the image.

Since: 2.22

gdk_image_get_width ()

gint
gdk_image_get_width (GdkImage *image);

Determines the width of the image.

Since: 2.22

gdk_image_get_pixels ()

gpointer
gdk_image_get_pixels (GdkImage *image);

Returns a pointer to the pixel data of the image.

Since: 2.22

gdk_image_put_pixel ()

void
gdk_image_put_pixel (GdkImage *image,
                     gint x,
                     gint y,
                     guint32 pixel);

gdk_image_get_pixel ()

guint32
gdk_image_get_pixel (GdkImage *image,
                     gint x,
                     gint y);
