Construct a WindowsNT specific TSLDrawingSurface.

Parameters

handle Reference to a HDC to which the TSLDrawingSurface is to be attached.

◆ TSLNTSurface() [3/3]

TSLNTSurface::TSLNTSurface ( TSLWindowHandle handle )

Construct a WindowsNT specific TSLDrawingSurface.

Parameters

handle Reference to a HWND to which the TSLDrawingSurface is to be attached.

◆ ~TSLNTSurface()

virtual TSLNTSurface::~TSLNTSurface ( )

virtual

Destructor.

Member Function Documentation

◆ clone()

virtual TSLDrawingSurface * TSLNTSurface::clone ( bool copyUserData = false )

virtual

This method clones the drawing surface and creates another drawing surface which reference the same data layers, data layer properties, options and coordinate system configuration.

Parameters

copyUserData If true, the userID and userWord will be copied to the new surface.

Returns: new cloned drawing surface, NULL on error.

Implements TSLDrawingSurface.

◆ colourValue()

TSLStyleID TSLNTSurface::colourValue ( int index )

Query colour value used by TSLDrawingSurface.

This method retrieves the colour definition used by the drawing surface for a given index. On Windows NT, the returned value contains the red, green and blue values of the colour used when creating the pen or brushes.

Parameters

index Index of the colour to retrieve.

Returns: colour value, or 0 on error.

◆ drawToHDC()

bool TSLNTSurface::drawToHDC	(	TSLDeviceContext	hDC,
		double	x1,
		double	y1,
		double	x2,
		double	y2,
		bool	clear,
		int	horizontalSizeMM = 0,
		int	verticalSizeMM = 0,
		int	horizontalSizePixels = 0,
		int	verticalSizePixels = 0 )

This method allows the TSLNTSurface to draw to a HDC to which it is not attached.

Typically this method would be used to request the TSLNTSurface to draw to a printer device context.

Note: the device co-ordinate system for the target HDC may not be the same as the one currently attached to the TSLDrawingSurface. Because of this, it may be necessary to do a temporary wndResize() and resize() on the TSLDrawingSurface.

Parameters

hDC	Handle of the device to draw to.
(x1,y1)	Bottom left co-ordinate (in user units) of the area to draw.
(x2,y2)	Top right co-ordinate (in user units) of the area to draw.
clear	If true this will clear the specified area before drawing any of the data.
horizontalSizeMM	Horizontal size of the visible screen in mm's. Defaults to system setting.
verticalSizeMM	Vertical size of the visible screen in mm's. Defaults to system setting.
horizontalSizePixels	Horizontal size of the screen in pixels. Defaults to system setting.
verticalSizePixels	Vertical size of the screen in pixels. Defaults to system setting.

◆ fillStyleValue()

bool TSLNTSurface::fillStyleValue	(	int	index,
		int	colour,
		HBITMAP	bitmap,
		TSLSimpleString *	section = 0 )

Query example fill rendering used by TSLDrawingSurface.

This method populates the specified bitmap with a sample of the specified fill. The bitmap is not cleared before filling, thus enabling translucent and stippled patterns to show the underling user rendered bitmap.

Parameters

index	Index of a fill style.
colour	Colour to fill with.
bitmap	Bitmap to populate with fill style rendering
section	If provided this will be populated with the section heading that this fill style appears under

Returns: true on success, false otherwise.

◆ fontStyleValue()

bool TSLNTSurface::fontStyleValue	(	int	index,
		int	colour,
		HBITMAP	bitmap,
		TSLSimpleString *	fontName = 0,
		const char *	outputString = 0,
		TSLSimpleString *	section = 0 )

Query example text rendering used by TSLDrawingSurface.

This method populates the specified bitmap with a sample of the specified text style. The bitmap is not cleared before drawing the text. The height of the bitmap is used define the height of the text. The text displayed is either the specified outputString, or the font name if no string is passed.

If required, the name of the font may be returned through the fontName parameter.

Parameters

index	Index of a font style
colour	Colour to display the text
bitmap	Bitmap to populate with text
fontName	Populated by the base name of the font (optional)
outputString	String to be displayed, otherwise font name is used (optional)
section	If provided this will be populated with the section heading that this font style appears under

Returns: true on success, false otherwise.

◆ lineStyleValue()

bool TSLNTSurface::lineStyleValue	(	int	index,
		int	colour,
		int	thickness,
		HBITMAP	bitmap,
		TSLSimpleString *	section = 0 )

Query example line rendering used by TSLDrawingSurface.

This method populates the specified bitmap with a sample of the specified line style. The bitmap is not cleared before rendering.

Parameters

index	Index of a line style
colour	Colour to draw line with
thickness	Thickness of line style, in pixels
bitmap	Bitmap to populate with line style rendering
section	If provided this will be populated with the section heading that this line style appears under

Returns: true on success, false otherwise.

◆ operator delete()

void TSLNTSurface::operator delete ( void * self )

◆ operator new() [1/2]

void * TSLNTSurface::operator new ( size_t size )

◆ operator new() [2/2]

void * TSLNTSurface::operator new	(	size_t	size,
		char *	filename,
		int	line )

When included in an MFC application in debug mode, the debug new expects this to be here. Override it and return the same as the normal one. The library must include it when compiled in release mode, since the user's application may be in debug mode.

◆ symbolStyleValue()

bool TSLNTSurface::symbolStyleValue	(	int	index,
		int	colour,
		HBITMAP	bitmap,
		uint32_t	fontSymbolCharacter = 0,
		TSLRasterSymbolScalable	rasterSymbolScalability = TSLRasterSymbolScalableAsSymbolFile,
		TSLSimpleString *	section = NULL,
		TSLSimpleString *	description = NULL,
		int *	originX = NULL,
		int *	originY = NULL )

Query example symbol rendering used by TSLDrawingSurface.

This method allows the user to populate a bitmap with a symbol, according to an index into the symbol list used by the drawing surface. The aim of this method is to give the user the ability of viewing the symbols used by the drawing surface.

The user creates the bitmap to be populated. The size of the bitmap is typically 32*32 pixels if the symbol is an icon.

Parameters

index	Index of a symbol style.
colour	Colour of the symbol.
bitmap	Bitmap to populate with symbol rendering
fontSymbolCharacter	If the symbol style index refers to a font symbol, this is the character that will be drawn using that font. The value is a Unicode Code Point.
rasterSymbolScalability	The symbol style index refers to a raster symbol, this flag will dictate the scalability of the symbol.
section	If provided this will be populated with the section heading that this symbol style appears under
description	If not null will be populated with the symbol's description
(originX,originY)	The returned origin of the symbol, in pixels (both originX and originY have to be passed in for them to be populated)

Returns: true on success, false otherwise.
