Member Function Documentation

◆ layoutUnitPtToPt() [1/2]

static KoPoint KoTextZoomHandler::layoutUnitPtToPt ( const KoPoint & p )

inlinestatic

Definition at line 127 of file KoTextZoomHandler.h.

◆ layoutUnitPtToPt() [2/2]

static double KoTextZoomHandler::layoutUnitPtToPt ( double lupt )

inlinestatic

Definition at line 125 of file KoTextZoomHandler.h.

◆ layoutUnitToFontSize()

double KoTextZoomHandler::layoutUnitToFontSize	(	int	luSize,
		bool
	)		const

Given the font size for the font in layout units, in pt (use pointSize()) this returns the font size to use on screen the current zoom, in pt (use setPointSizeFloat()),.

Definition at line 39 of file KoTextZoomHandler.cpp.

◆ layoutUnitToPixel() [1/2]

TQPoint KoTextZoomHandler::layoutUnitToPixel ( const TQPoint & p ) const

inline

Definition at line 57 of file KoTextZoomHandler.h.

◆ layoutUnitToPixel() [2/2]

TQRect KoTextZoomHandler::layoutUnitToPixel ( const TQRect & r ) const

inline

Definition at line 60 of file KoTextZoomHandler.h.

◆ layoutUnitToPixelX() [1/2]

int KoTextZoomHandler::layoutUnitToPixelX ( int lupix ) const

The "layout unit pixel" -> "[zoomed] view pixel" conversions.

Definition at line 65 of file KoTextZoomHandler.cpp.

◆ layoutUnitToPixelX() [2/2]

int KoTextZoomHandler::layoutUnitToPixelX	(	int	x,
		int	w
	)		const

This variant converts a width, using a reference X position.

This prevents rounding problems.

Definition at line 49 of file KoTextZoomHandler.cpp.

◆ layoutUnitToPixelY() [1/2]

int KoTextZoomHandler::layoutUnitToPixelY ( int lupix ) const

Definition at line 71 of file KoTextZoomHandler.cpp.

◆ layoutUnitToPixelY() [2/2]

int KoTextZoomHandler::layoutUnitToPixelY	(	int	y,
		int	h
	)		const

This variant converts a height, using a reference Y position.

This prevents rounding problems.

Definition at line 57 of file KoTextZoomHandler.cpp.

Definition at line 42 of file KoTextZoomHandler.h.

◆ pixelToLayoutUnitX()

int KoTextZoomHandler::pixelToLayoutUnitX ( int x ) const

The "[zoomed] view pixel" -> "layout unit pixel" conversions.

inline

Definition at line 87 of file KoTextZoomHandler.h.

◆ ptToLayoutUnitPixX()

int KoTextZoomHandler::ptToLayoutUnitPixX ( double x_pt ) const

inline

The "document pt" -> "Layout Unit pixels" conversions, for convenience.

Definition at line 83 of file KoTextZoomHandler.h.

◆ ptToLayoutUnitPixY()

int KoTextZoomHandler::ptToLayoutUnitPixY ( double y_pt ) const

inlinestatic

Definition at line 121 of file KoTextZoomHandler.h.

◆ ptToLayoutUnitPt() [3/4]

static double KoTextZoomHandler::ptToLayoutUnitPt ( double pt )

inlinestatic

Not zoom dependent.

Simply convert a pt value (e.g. a frame) to high-resolution layout unit coordinates (in pt).

Definition at line 112 of file KoTextZoomHandler.h.

◆ ptToLayoutUnitPt() [4/4]

static int KoTextZoomHandler::ptToLayoutUnitPt ( int ptSize )

inlinestatic

Same thing for integer values, e.g.

a font size in pt

Definition at line 115 of file KoTextZoomHandler.h.

◆ ptToPixel()

TQPoint KoTextZoomHandler::ptToPixel ( const KoPoint & p ) const

inline

Definition at line 71 of file KoTextZoomHandler.h.

◆ ptToPixelX()

int KoTextZoomHandler::ptToPixelX ( double pt ) const

inline

Basic pt to pixel and pixel to pt conversions, valid at any zoom level, as well as at the Layout Unit level (and mostly useful for Layout Units).

Don't confuse with zoomIt, which also converts pt to pixels, but applying the zoom!

Definition at line 67 of file KoTextZoomHandler.h.

◆ ptToPixelY()

int KoTextZoomHandler::ptToPixelY ( double pt ) const

inline

Definition at line 69 of file KoTextZoomHandler.h.

◆ setPtToLayoutUnitFactor()

static void KoTextZoomHandler::setPtToLayoutUnitFactor ( int factor )

inlinestatic

Change the factor that converts between pointsizes and layout units (by default 20 - for 1440 DPI at 72 DPI)

Definition at line 108 of file KoTextZoomHandler.h.
