Gdi

Windows CE .NET

This class provides access to internal graphics device interface (GDI) functions that you can use when drawing controls.

Method Description
Gdi::AbortDoc_I Stops the current print job.
Gdi::AddFontResourceW_I Adds the font resource from the specified file to the font table for Microsoft® Windows® CE .NET. Any Windows CE–based application can subsequently use the font for text output.
Gdi::BitBlt_I Transfers pixels from a specified source rectangle to a specified destination rectangle, altering the pixels according to the selected raster operation (ROP) code.
Gdi::CeRemoveFontResource_I Removes a font resource identified by a specified object identifier.
Gdi::CombineRgn_I Combines two regions and stores the result in a third region. The Gdi::CombineRgn_I method combines the two regions according to the specified mode.
Gdi::CreateBitmap_I Creates a bitmap with the specified width, height, and bit depth.
Gdi::CreateCompatibleBitmap_I Creates a bitmap compatible with the device associated with the specified device context.

Gdi::CreateDIBPatternBrushPt_I Creates a logical brush that has the pattern specified by the device-independent bitmap (DIB).
Gdi::CreateFontIndirectW_I Creates a logical font that has the characteristics specified in the specified LOGFONT structure. You can subsequently select the font as the current font for any device context.
Gdi::CreatePalette_I Creates a logical color palette.

Gdi::DibByteWidth Retrieves the number of bytes in each scan line. This value must be divisible by 2, because the operating system (OS) assumes that the bit values of a bitmap form an array that is word aligned.
Gdi::DibSize Retrieves the size, in bytes, of the image. This value can be zero for BI_RGB bitmaps.
Gdi::DrawEdge_I Draws one or more edges of a rectangle.
Gdi::DrawFocusRect_I Draws a rectangle in the style used to indicate that the rectangle has the focus.
Gdi::DrawTextW_I Draws formatted text in the specified rectangle, formatting the text according to the specified format method.

Gdi::EnableEUDC_I Enables or disables end-user-defined characters (EUDC).
Gdi::EndDoc_I Ends a print job.
Gdi::EndPage_I Informs the device that the application has finished writing to a page. An application typically uses this function to direct the device driver to advance to a new page.
Gdi::EnumDisplayMonitors_I Enumerates screens that intersect a region formed by the intersection of a specified clipping rectangle and the visible region of a specified device context.
Gdi::EnumFontFamiliesW_I Enumerates the fonts in a specified font family that are available on a specified device. This function supersedes the Gdi::EnumFontsW_I method.
Gdi::EnumFontsW_I Enumerates the fonts available on a specified device. This method is provided for compatibility with earlier versions of the Microsoft Windows SDK. Whenever possible, applications should use the Gdi::EnumFontFamiliesW_I method.
Gdi::ExcludeClipRect_I Creates a new clipping region that consists of the existing clipping region minus the specified rectangle.
Gdi::ExtEscape_I Allows applications to access capabilities of a particular device that are not available through the graphics display interface (GDI). The OEM must implement the device capabilities that this function accesses.
