GeClipMap Class Reference

#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.

Returns
BaseContainer with fonts.

◆ ClearFontListCache()

◆ IsFontInstalled()

static Bool IsFontInstalled ( const BaseContainer fontDescription,
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]fontDescriptionThe font description to check.
[out]installedFontDescriptionOptional. 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]fontDescriptionThe font description.
[in]isFontInstalledOptional 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]fontDescriptionThe font description.
Returns
The raw font name.
