phoenix_title wx.DC

A wx.DC is a “device context” onto which graphics and text can be drawn.

It is intended to represent different output devices and offers a common abstract API for drawing on any of them.

wxWidgets offers an alternative drawing API based on the modern drawing backends GDI+, CoreGraphics and Cairo. See wx.GraphicsContext, wx.GraphicsRenderer and related classes. There is also a wx.GCDC linking the APIs by offering the wx.DC API on top of a wx.GraphicsContext.

wx.DC is an abstract base class and cannot be created directly. Use wx.PaintDC, wx.ClientDC, wx.WindowDC, wx.ScreenDC, wx.MemoryDC or wx.PrinterDC. Notice that device contexts which are associated with windows (i.e. wx.ClientDC, wx.WindowDC and wx.PaintDC) use the window font and colours by default (starting with wxWidgets 2.9.0) but the other device context classes use system-default values so you always must set the appropriate fonts and colours before using them.

In addition to the versions of the methods documented below, there are also versions which accept single wx.Point parameter instead of the two int ones or wx.Point and wx.Size instead of the four int parameters.

Beginning with wxWidgets 2.9.0 the entire wx.DC code has been reorganized. All platform dependent code (actually all drawing code) has been moved into backend classes which derive from a common DCImpl class. The user-visible classes such as wx.ClientDC and wx.PaintDC merely forward all calls to the backend implementation.

phoenix_title Device and logical units

In the wx.DC context there is a distinction between logical units and device units. Device units are the units native to the particular device; e.g. for a screen, a device unit is a pixel. For a printer, the device unit is defined by the resolution of the printer (usually given in DPI: dot-per-inch). All wx.DC functions use instead logical units, unless where explicitly stated. Logical units are arbitrary units mapped to device units using the current mapping mode (see wx.DC.SetMapMode ). This mechanism allows to reuse the same code which prints on e.g. a window on the screen to print on e.g. a paper.

phoenix_title Support for Transparency / Alpha Channel

In general wx.DC methods don’t support alpha transparency and the alpha component of wx.Colour is simply ignored and you need to use wx.GraphicsContext for full transparency support. There are, however, a few exceptions: first, under Mac OS X colours with alpha channel are supported in all the normal DC-derived classes as they use wx.GraphicsContext internally. Second, under all platforms wx.SVGFileDC also fully supports alpha channel. In both of these cases the instances of wx.Pen or wx.Brush that are built from wx.Colour use the colour’s alpha values when stroking or filling.

phoenix_title for Transformation Matrix

On some platforms (currently only under MSW and only on Windows NT, i.e. not Windows 9x/ME, systems) wx.DC has support for applying an arbitrary affine transformation matrix to its coordinate system. Call CanUseTransformMatrix to check if this support is available and then call SetTransformMatrix if it is. If the transformation matrix is not supported, SetTransformMatrix always simply returns False and doesn’t do anything.

class wx.DC(Object)

A DC is a “device context” onto which graphics and text can be drawn.


Methods


Blit(self, xdest, ydest, width, height, source, xsrc, ysrc, logicalFunc=COPY, useMask=False, xsrcMask=DefaultCoord, ysrcMask=DefaultCoord)

Copy from a source DC to this DC.

With this method you can specify the destination coordinates and the size of area to copy which will be the same for both the source and target DCs. If you need to apply scaling while copying, use StretchBlit .

Notice that source DC coordinates xsrc and ysrc are interpreted using the current source DC coordinate system, i.e. the scale, origin position and axis directions are taken into account when transforming them to physical (pixel) coordinates.

Parameters:
  • xdest (int) – Destination device context x position.
  • ydest (int) – Destination device context y position.
  • width (int) – Width of source area to be copied.
  • height (int) – Height of source area to be copied.
  • source (wx.DC) – Source device context.
  • xsrc (int) – Source device context x position.
  • ysrc (int) – Source device context y position.
  • logicalFunc (RasterOperationMode) – Logical function to use, see SetLogicalFunction .
  • useMask (bool) – If True, Blit does a transparent blit using the mask that is associated with the bitmap selected into the source device context. The Windows implementation does the following if MaskBlt cannot be used:
    • Creates a temporary bitmap and copies the destination area into it.
    • Copies the source area into the temporary bitmap using the specified logical function.
    • Sets the masked area in the temporary bitmap to wx.BLACK by ANDing the mask bitmap with the temp bitmap with the foreground colour set to wx.WHITE and the bg colour set to wx.BLACK.
    • Sets the unmasked area in the destination area to wx.BLACK by ANDing the mask bitmap with the destination area with the foreground colour set to wx.BLACK and the background colour set to wx.WHITE.
    • ORs the temporary bitmap with the destination area.
    • Deletes the temporary bitmap.

    This sequence of operations ensures that the source’s transparent area need not be black, and logical functions are supported.

    Note: on Windows, blitting with masks can be speeded up considerably by compiling wxWidgets with the USE_DC_CACHEING option enabled. You can also influence whether MaskBlt or the explicit mask blitting code above is used, by using wx.SystemOptions and setting the no-maskblt option to 1.
  • xsrcMask (int) – Source x position on the mask. If both xsrcMask and ysrcMask are -1 , xsrc and ysrc will be assumed for the mask source position. Currently only implemented on Windows.
  • ysrcMask (int) – Source y position on the mask. If both xsrcMask and ysrcMask are -1 , xsrc and ysrc will be assumed for the mask source position. Currently only implemented on Windows.
Return type:

bool

Note

There is partial support for Blit in wx.PostScriptDC, under X.

DrawText(self, *args, **kw)

overload Overloaded Implementations:


DrawText (self, text, x, y)

Draws a text string at the specified point, using the current text font, and the current text foreground and background colours.

The coordinates refer to the top-left corner of the rectangle bounding the string. See GetTextExtent for how to get the dimensions of a text string, which can be used to position the text more precisely and DrawLabel if you need to align the string differently.

Starting from wxWidgets 2.9.2 text parameter can be a multi-line string, i.e. contain new line characters, and will be rendered correctly.

Parameters:
  • text (string) –
  • x (int) –
  • y (int) –

Note

The current logical function is ignored by this function.


DrawText (self, text, pt)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters:



DrawTextList(self, textList, coords, foregrounds=None, backgrounds=None)

Draw a list of strings using a list of coordinants for positioning each string.

Parameters:
  • textList – A list of strings
  • coords – A list of (x,y) positions
  • foregrounds – A list of wx.Colour objects to use for the foregrounds of the strings.
  • backgrounds – A list of wx.Colour objects to use for the backgrounds of the strings.
NOTE: Make sure you set background mode to wx.Solid (DC.SetBackgroundMode)
If you want backgrounds to do anything.

FloodFill(self, *args, **kw)

overload Overloaded Implementations:


FloodFill (self, x, y, colour, style=FLOOD_SURFACE)

Flood fills the device context starting from the given point, using the current brush colour, and using a style:

  • wx.FLOOD_SURFACE: The flooding occurs until a colour other than the given colour is encountered.
  • wx.FLOOD_BORDER: The area to be flooded is bounded by the given colour.

Currently this method is not implemented in wxOSX and does nothing there.

Parameters:
Return type:

bool
Returns:

False if the operation failed.

Note

The present implementation for non-Windows platforms may fail to find colour borders if the pixels do not match the colour exactly. However the function will still return True.

Note

This method shouldn’t be used with wx.PaintDC under non-Windows platforms as it uses GetPixel internally and this may give wrong results, notably in wxGTK. If you need to flood fill wx.PaintDC, create a temporary wx.MemoryDC, flood fill it and then blit it to, or draw as a bitmap on, wx.PaintDC. See the example of doing this in the drawing sample and wx.BufferedPaintDC class.


FloodFill (self, pt, col, style=FLOOD_SURFACE)

SetClippingRegion(self, *args, **kw)

overload Overloaded Implementations:


SetClippingRegion (self, x, y, width, height)

Sets the clipping region for this device context to the intersection of the given region described by the parameters of this method and the previously set clipping region.

The clipping region is an area to which drawing is restricted. Possible uses for the clipping region are for clipping text or for speeding up window redraws when only a known area of the screen is damaged.

Notice that you need to call DestroyClippingRegion if you want to set the clipping region exactly to the region specified.

Also note that if the clipping region is empty, any previously set clipping region is destroyed, i.e. it is equivalent to calling DestroyClippingRegion , and not to clipping out all drawing on the DC as might be expected.

Parameters:
  • x (int) –
  • y (int) –
  • width (int) –
  • height (int) –

Parameters:


SetClippingRegion (self, rect)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Parameters:rect (wx.Rect) –



SetDeviceClippingRegion(self, region)

Sets the clipping region for this device context.

Unlike SetClippingRegion , this function works with physical coordinates and not with the logical ones.

Parameters:region (wx.Region) –

SetDeviceOrigin(self, x, y)

Sets the device origin (i.e. the origin in pixels after scaling has been applied).

This function may be useful in Windows printing operations for placing a graphic on a page.

Parameters:
  • x (int) –
  • y (int) –

SetFont(self, font)

Sets the current font for the DC.

If the argument is wx.NullFont (or another invalid font; see wx.Font.IsOk ), the current font is selected out of the device context (leaving wx.DC without any valid font), allowing the current font to be destroyed safely.

Parameters:font (wx.Font) –

See also

wx.Font


SetLayoutDirection(self, dir)

Sets the current layout direction for the device context.

Parameters:dir (LayoutDirection) – May be either Layout_Default , Layout_LeftToRight or Layout_RightToLeft .

See also

GetLayoutDirection


SetLogicalFunction(self, function)

Sets the current logical function for the device context.

It determines how a source pixel (from a pen or brush colour, or source device context if using Blit ) combines with a destination pixel in the current device context. Text drawing is not affected by this function.

See wx.RasterOperationMode enumeration values for more info.

The default is COPY , which simply draws with the current colour. The others combine the current colour and the background using a logical operation. INVERT is commonly used for drawing rubber bands or moving outlines, since drawing twice reverts to the original colour.

Parameters:function (RasterOperationMode) –

SetLogicalOrigin(self, x, y)

Change the offset used for translating wx.DC coordinates.

Parameters:
  • x (int) –
  • y (int) –

See also

SetLogicalOrigin , SetDeviceOrigin


SetLogicalScale(self, x, y)

Set the scale to use for translating wx.DC coordinates to the physical pixels.

The effect of calling this function is similar to that of calling SetUserScale .

Parameters:
  • x (float) –
  • y (float) –

SetMapMode(self, mode)

The mapping mode of the device context defines the unit of measurement used to convert logical units to device units.

Note that in X, text drawing isn’t handled consistently with the mapping mode; a font is always specified in point size. However, setting the user scale (see SetUserScale ) scales the text appropriately. In Windows, scalable TrueType fonts are always used; in X, results depend on availability of fonts, but usually a reasonable match is found.

The coordinate origin is always at the top left of the screen/printer.

Drawing to a Windows printer device context uses the current mapping mode, but mapping mode is currently ignored for PostScript output.

Parameters:mode (MappingMode) –

SetPalette(self, palette)

If this is a window DC or memory DC, assigns the given palette to the window or bitmap associated with the DC.

If the argument is wx.NullPalette , the current palette is selected out of the device context, and the original palette restored.

Parameters:palette (wx.Palette) –

See also

wx.Palette


SetPen(self, pen)

Sets the current pen for the DC.

If the argument is wx.NullPen (or another invalid pen; see wx.Pen.IsOk ), the current pen is selected out of the device context (leaving wx.DC without any valid pen), allowing the current pen to be destroyed safely.

Parameters:pen (wx.Pen) –

See also

wx.MemoryDC for the interpretation of colours when drawing into a monochrome bitmap.


SetTextBackground(self, colour)

Sets the current text background colour for the DC.

Parameters:colour (wx.Colour) –

SetTextForeground(self, colour)

Sets the current text foreground colour for the DC.

Parameters:colour (wx.Colour) –

See also

wx.MemoryDC for the interpretation of colours when drawing into a monochrome bitmap.


SetTransformMatrix(self, matrix)

Set the transformation matrix.

If transformation matrix is supported on the current system, the specified matrix will be used to transform between wx.DC and physical coordinates. Otherwise the function returns False and doesn’t change the coordinate mapping.

Parameters:matrix (wx.AffineMatrix2D) –
Return type:bool

New in version 2.9.2.


SetUserScale(self, xScale, yScale)

Sets the user scaling factor, useful for applications which require ‘zooming’.

Parameters:
  • xScale (float) –
  • yScale (float) –

StartDoc(self, message)

message is a message to show while printing.

Parameters:message (string) –
Return type:bool

StartPage(self)

Starts a document page (only relevant when outputting to a printer).


StretchBlit(self, xdest, ydest, dstWidth, dstHeight, source, xsrc, ysrc, srcWidth, srcHeight, logicalFunc=COPY, useMask=False, xsrcMask=DefaultCoord, ysrcMask=DefaultCoord)

Copy from a source DC to this DC possibly changing the scale.

Unlike Blit , this method allows to specify different source and destination region sizes, meaning that it can stretch or shrink it while copying. The same can be achieved by changing the scale of the source or target DC but calling this method is simpler and can also be more efficient if the platform provides a native implementation of it.

The meaning of its other parameters is the same as with Blit , in particular all source coordinates are interpreted using the source DC coordinate system, i.e. are affected by its scale, origin translation and axis direction.

Parameters:
  • xdest (int) – Destination device context x position.
  • ydest (int) – Destination device context y position.
  • dstWidth (int) – Width of destination area.
  • dstHeight (int) – Height of destination area.
  • source (wx.DC) – Source device context.
  • xsrc (int) – Source device context x position.
  • ysrc (int) – Source device context y position.
  • srcWidth (int) – Width of source area to be copied.
  • srcHeight (int) – Height of source area to be copied.
  • logicalFunc (RasterOperationMode) – Logical function to use, see SetLogicalFunction .
  • useMask (bool) – If True, Blit does a transparent blit using the mask that is associated with the bitmap selected into the source device context. The Windows implementation does the following if MaskBlt cannot be used:
    • Creates a temporary bitmap and copies the destination area into it.
    • Copies the source area into the temporary bitmap using the specified logical function.
    • Sets the masked area in the temporary bitmap to wx.BLACK by ANDing the mask bitmap with the temp bitmap with the foreground colour set to wx.WHITE and the bg colour set to wx.BLACK.
    • Sets the unmasked area in the destination area to wx.BLACK by ANDing the mask bitmap with the destination area with the foreground colour set to wx.BLACK and the background colour set to wx.WHITE.
    • ORs the temporary bitmap with the destination area.
    • Deletes the temporary bitmap.

    This sequence of operations ensures that the source’s transparent area need not be black, and logical functions are supported.

    Note: on Windows, blitting with masks can be speeded up considerably by compiling wxWidgets with the USE_DC_CACHEING option enabled. You can also influence whether MaskBlt or the explicit mask blitting code above is used, by using wx.SystemOptions and setting the no-maskblt option to 1.
  • xsrcMask (int) – Source x position on the mask. If both xsrcMask and ysrcMask are DefaultCoord, xsrc and ysrc will be assumed for the mask source position. Currently only implemented on Windows.
  • ysrcMask (int) – Source y position on the mask. If both xsrcMask and ysrcMask are DefaultCoord, xsrc and ysrc will be assumed for the mask source position. Currently only implemented on Windows.
Return type:

bool

Blit in wx.PostScriptDC, under X.

See wx.MemoryDC for typical usage.
