Package: Pixmap

Description

package Gdk.Pixmap is

Pixmaps are off-screen drawables. They can be drawn upon with the standard drawing primitives, then copied to another drawable (such as a Gdk_Window) with Gdk.Drawable.Draw_Drawable. The depth of a pixmap is the number of bits per pixels. Bitmaps are simply pixmaps with a depth of 1. (That is, they are monochrome bitmaps - each pixel can be either on or off).

See Gdk.Bitmap for more details on bitmap handling.

Binding from C File version 1.3.6

Types

Gdk_Pixmap 

subtype Gdk_Pixmap is Gdk.Gdk_Pixmap;
A server-side image. You can create an empty pixmap, or load if from external files in bitmap and pixmap format. See Gdk.Pixbuf if you need to load images in other formats.

Constants & Global variables

Null_Pixmap (Gdk_Pixmap) 

Null_Pixmap : constant Gdk_Pixmap;

Subprograms & Entries

Gdk_New 

procedure Gdk_New 
(Pixmap: out Gdk_Pixmap;
Window: Gdk.Window.Gdk_Window;
Width: Gint;
Height: Gint;
Depth: Gint := -1);
Create a new pixmap with a given size. Window is used to determine default values for the new pixmap. Can be eventually null. Width is the width of the new pixmap in pixels. Height is the height of the new pixmap in pixels. Depth is the depth (number of bits per pixel) of the new pixmap. If -1, and window is not null, the depth of the new pixmap will be equal to that of window. Automatically reference the pixmap once.

Get_Type 

function Get_Type return Glib.GType;
Return the internal value associated with Gdk_Pixmap.

Ref 

procedure Ref 
(Pixmap: Gdk_Pixmap);
Add a reference to a pixmap.

Unref 

procedure Unref 
(Pixmap: Gdk_Pixmap);
This is the usual way to destroy a pixmap. The memory is freed when there is no more reference

Create_From_Data 

procedure Create_From_Data 
(Pixmap: out Gdk_Pixmap;
Window: Gdk.Window.Gdk_Window;
Data: String;
Width: Gint;
Height: Gint;
Depth: Gint;
Fg: Color.Gdk_Color;
Bg: Color.Gdk_Color);
Create a pixmap from data in XBM format. Window is used to determine default values for the new bitmap, can be null in which case the root window is used. Data is the XBM data. Width is the width of the new bitmap in pixels. Height is the height of the new bitmap in pixels. Depth is the depth (number of bits per pixel) of the new pixmap. Fg is the foreground color. Bg is the background color.

Create_From_Xpm 

procedure Create_From_Xpm 
(Pixmap: out Gdk_Pixmap;
Window: Gdk.Window.Gdk_Window;
Mask: in out Gdk.Bitmap.Gdk_Bitmap;
Transparent: Gdk.Color.Gdk_Color;
Filename: String);
Create a pixmap from a XPM file. Window is used to determine default values for the new pixmap. Mask is a pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be null, in which case transparency will be ignored. Transparent is the color to be used for the pixels that are transparent in the input file. Can be null, in which case a default color will be used. Filename is the filename of a file containing XPM data.

Create_From_Xpm 

procedure Create_From_Xpm 
(Pixmap: out Gdk_Pixmap;
Window: Gdk.Window.Gdk_Window;
Colormap: Gdk.Color.Gdk_Colormap;
Mask: in out Gdk.Bitmap.Gdk_Bitmap;
Transparent: Gdk.Color.Gdk_Color;
Filename: String);
Create a pixmap from a XPM file using a particular colormap. Window is used to determine default values for the new pixmap. Can be null if colormap is given. Colormap is the Gdk_Colormap that the new pixmap will use. If omitted, the colormap for window will be used. Mask is a pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be null, in which case transparency will be ignored. Transparent is the color to be used for the pixels that are transparent in the input file. Can be null, in which case a default color will be used. Filename is the filename of a file containing XPM data.

Create_From_Xpm_D 

procedure Create_From_Xpm_D 
(Pixmap: out Gdk_Pixmap;
Window: Gdk.Window.Gdk_Window;
Mask: in out Gdk.Bitmap.Gdk_Bitmap;
Transparent: Gdk.Color.Gdk_Color;
Data: Gtkada.Types.Chars_Ptr_Array);
Create a pixmap from data in XPM format. Window is used to determine default values for the new pixmap. Mask is a pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be null, in which case transparency will be ignored. Transparent will be used for the pixels that are transparent in the input file. Can be null in which case a default color will be used. Data is a pointer to a string containing the XPM data.

Create_From_Xpm_D 

procedure Create_From_Xpm_D 
(Pixmap: out Gdk_Pixmap;
Window: Gdk.Window.Gdk_Window;
Colormap: Gdk.Color.Gdk_Colormap;
Mask: in out Gdk.Bitmap.Gdk_Bitmap;
Transparent: Gdk.Color.Gdk_Color;
Data: Gtkada.Types.Chars_Ptr_Array);
Create a pixmap from data in XPM format using a particular colormap. Window is used to determine default values for the new pixmap. Colormap is the Gdk_Colormap that the new pixmap will be use. If omitted, the colormap for window will be used. Mask is a pointer to a place to store a bitmap representing the transparency mask of the XPM file. Can be null, in which case transparency will be ignored. Transparent will be used for the pixels that are transparent in the input file. Can be null in which case a default color will be used. Data is a pointer to a string containing the XPM data.
