If you are using Gtk, the usual way to obtain a is . Method System.Void Fills and with the size of the Drawable. or can be if you only want the other one. A A On the X11 platform, if this Drawable object is also a , the returned size is the size reported in the most-recently-processed configure event, rather than the current size on the X server. Method System.Void Draws a number of unconnected lines. A A , a list of segments to draw. A , the number of segments. TODO: Drawable.custom needs to be edited to make segs an array of Gdk.Segment objects. Method System.Void Low-level glyph drawing function. A A A A A This is a low-level function; 99% of text rendering should be done using instead. A glyph is a character in a font. This function draws a sequence of glyphs. To obtain a sequence of glyphs you have to understand a lot about internationalized text handling, which you don't want to understand; thus, use instead of this function, handles the details. Method Gdk.Image Returns a client-side representing the server-side . A , X coordinate of the upper left corner of the region to get as a drawable A , Y coordinate of the upper left corner of the region to get as a drawable. A , width of the rectangle A , height of the rectangle. A containing the contents of this Drawable object. A stores client-side image data (pixels). In contrast, and are server-side objects. This method obtains the pixels from a server-side drawable as a client-side . The format of a depends on the of the current display, which makes manipulating extremely difficult; therefore, in most cases you should use instead of this lower-level function. A contains image data in a canonicalized RGB format, rather than a display-dependent format. Of course, there's a convenience vs. speed tradeoff here, so you'll want to think about what makes sense for your application. , , , and define the region of the drawable to obtain as an image. You would usually copy image data to the client side if you intend to examine the values of individual pixels, for example to darken an image or add a red tint. It would be prohibitively slow to make a round-trip request to the windowing system for each pixel, so instead you get all of them at once, modify them, then copy them all back at once. If the X server or other windowing system backend is on the local machine, this function may use shared memory to avoid copying the image data. If the source drawable is a #GdkWindow and partially offscreen or obscured, then the obscured portions of the returned image will contain undefined data. Method System.Void Draws a portion of a drawable into another. A A , the source Drawable. A A A A A A Copies the x region of at coordinates (, ) to coordinates (, ) in . and/or may be given as -1, in which case the entire drawable will be copied. Most fields in are not used for this operation, but notably the clip mask or clip region will be honored. The source and destination drawables must have the same visual and colormap, or errors will result. (On X11, failure to match visual/colormap results in a BadMatch error from the X server.) A common cause of this problem is an attempt to draw a bitmap to a color drawable. The way to draw a bitmap is to set the bitmap as a clip mask on your #GdkGC, then use to draw a rectangle clipped to the bitmap. Method System.Void Draws a onto a drawable. A A A A A A A A The depth of the must match the depth of the . Method System.Void Draws a point at (,). A A A Constructor Internal constructor Pointer to the C object. This is an internal constructor, and should not be used by user code. Property Gdk.Colormap The color map for this Drawable. The current on the Drawable. You only need to set the color map if the drawable-creating function did not have a way to determine the colormap, and you then use drawable operations that require a colormap. The colormap for all drawables and graphics contexts you intend to use together should match. i.e. when using a #GdkGC to draw to a drawable, or copying one drawable to another, the colormaps should match. Property Gdk.Region Computes the region of a drawable that is potentially visible. A This does not necessarily take into account if the window is obscured by other windows, but no area outside of this region is visible. You must call when done. Property Gdk.Region Computes the region of a drawable that potentially can be written to by drawing primitives. A . You must call when done. Computes the region of a drawable that potentially can be written to by drawing primitives. This region will not take into account the clip region for the GC, and may also not take into account other factors such as if the window is obscured by other windows, but no area outside of this region will be affected by drawing primitives. You must call the Destroy method on the returned region when done. Property Gdk.Visual Gets the describing the pixel format of drawable. A Property System.Int32 Obtains the bit depth of the drawable. The bit depth. Obtains the bit depth of the drawable, that is, the number of bits that make up a pixel in the drawable's visual. Examples are 8 bits per pixel, 24 bits per pixel, etc. Property Gdk.Screen Gets the associated with a a Property Gdk.Display Gets the associated with the . The . Method System.Void Draws a series of lines connecting the given points. a a The way in which joins between lines are draw is determined by the value in the . This can be set with property.

Use the overload which takes a for Method System.Void Draws a rectangular outline or filled rectangle, using the foreground color and other attributes of the . a a a A rectangle drawn filled is 1 pixel smaller in both dimensions than a rectangle outlined. Calling Gdk.DrawRectangle (window, gc, TRUE, 0, 0, 20, 20) results in a filled rectangle 20 pixels wide and 20 pixels high. Calling Gdk.DrawRectangle (window, gc, FALSE, 0, 0, 20, 20) results in an outlined rectangle with corners at (0, 0), (0, 20), (20, 20), and (20, 0), which makes it 21 pixels wide and 21 pixels high. Method System.Void Draws a line, using the foreground color and other attributes of the a a a a a Method System.Void Draws an arc or a filled 'pie slice'. The arc is defined by the bounding rectangle of the entire ellipse, and the start and end angles of the part of the ellipse to be drawn. a true if the arc should be filled, producing a 'pie slice'. The x-coordinate of the upper left hand of the bounding box of the arc. The y-coordinate of the upper left hand of the bounding box of the arc. the width of the bounding rectangle. the height of the bounding rectangle. The starting angle of the arc in the clockwise direction in reference to the 3'oclock position in terms of 1/64th of a degree. The number of 1/64ths of a degree to sweep the arc in a clockwise direction relative to the starting angle. Draw the left side of a circle with a radius of 5 units. Gdk.Pixmap.DrawArc(gc, false, 0, 0, 10, 10, 90 * 64, 180 * 64); Method System.Void Renders a rectangular portion of a to a A used for clipping. The to render Source X coordinate within pixbuf. Source Y coordinates within pixbuf. Destination X coordinate within drawable. Destination Y coordinate within drawable. Width of region to render, in pixels, or -1 to use pixbuf width. Height of region to render, in pixels, or -1 to use pixbuf height. Dithering mode for GdkRGB. X offset for dither. Y offset for dither. The destination drawable must have a colormap. All windows have a colormap, however, pixmaps only have colormap by default if they were created with a non-NULL window argument. Otherwise a colormap must be set on them on the property. On older X servers, rendering pixbufs with an alpha channel involves round trips to the X server, and may be somewhat slow. The clip mask of gc is ignored, but clip rectangles and clip regions work fine.

Calling Gdk.DrawRectangle (window, gc, TRUE, 0, 0, 20, 20) results in a filled rectangle 20 pixels wide and 20 pixels high. Calling Gdk.DrawRectangle (window, gc, FALSE, 0, 0, 20, 20) results in an outlined rectangle with corners at (0, 0), (0, 20), (20, 20), and (20, 0), which makes it 21 pixels wide and 21 pixels high.
