#include <lib_clipmap.h>

Detailed Description

This class stores and manipulates a bitmap, providing more advanced drawing tools than BaseBitmap.
Be sure to call Init() before trying to use a newly allocated clip map.

Note: Though clip maps support other bit depths than 32, the functionality is severely limited.
It is recommended that the clip map class is only used for 32 bit bitmaps. (Please note that the default bit depth for BaseBitmap is 24).; Has to be created with Alloc() and destroyed with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

◆ GetFontListFlat()

static const BaseContainer& GetFontListFlat ( )

They can be used with GeClipMap::SetFont(), GeClipMap::GetFontName() or as input for GeChooseFont().

Returns: BaseContainer with fonts.

◆ ClearFontListCache()

static void ClearFontListCache ( )

static

Clears the cached font lists, which will be rebuilt when calling GeClipMap::GetFontListHierarchical() or GeClipMap::GetFontListFlat(). Suitable to include new/removed fonts.

◆ GetDefaultFont()

static Bool GetDefaultFont	(	GeFontDefaultType	type,
		BaseContainer *	font_description

		BaseContainer *	installedFontDescription = `nullptr`
	)

static

Checks if fontDescription is installed in the operating system.

See also: GeClipMap::GetInstalledFont()

Note: An empty font description is a special case: will return true because is considered as a default Cinema 4D system font.

Parameters

[in]	fontDescription	The font description to check.
[out]	installedFontDescription	Optional. If a container is defined and result is true, then in this container is stored the font description as is fetched from the operating system. Nothing is set here with the special case of passing an empty container. If a container is defined, result is false but a matching font family has been found, then here are stored all fonts of that matching font family, so can be used as fallback fonts.

Returns: true if font description is installed, otherwise false.

◆ GetInstalledFont()

static BaseContainer GetInstalledFont	(	const BaseContainer &	fontDescription,
		Bool *	isFontInstalled = `nullptr`
	)

static

Returns a valid (installed) font description that closely matches the input fontDescription.

See also: GeClipMap::IsFontInstalled() It works as follows: if fontDescription is installed, then it returns the installed font description as GeClipMap::IsFontInstalled() does with the optional parameter. If not installed but a matching font family is found, then it returns a font of that family. A special case is when fontDescription is empy: as GeClipMap::IsFontInstalled() does, it just returns an empty container since is considered valid. In any other case it returns the system font like GeClipMap::GetDefaultFont() does with GE_FONT_DEFAULT_SYSTEM set.

Parameters

[in]	fontDescription	The font description.
[in]	isFontInstalled	Optional parameter. Is set to true if fontDescription is installed in the operating system, otherwise, even if a matching font family has been found, is set to false.

Returns: A valid font description.

◆ GetRawFontName()

static String GetRawFontName ( const BaseContainer & fontDescription )

static

Gets the font name stored in the input font description, without checking agaisnt installed fonts.

Note: Empty result means is a default Cinema 4D system font description.

Parameters

[in] fontDescription The font description.

Returns: The raw font name.
