Constructor & Destructor Documentation

◆ FontDescription()

open3d::visualization::gui::FontDescription::FontDescription ( const char *  typeface,
FontStyle  style = FontStyle::NORMAL,
int  point_size = 0 
)
explicit

Creates a font description. This must be passed to Application::AddFont() before the window is created.

Parameters
typefaceA path to a TrueType (.ttf), TrueType Collection (.ttc), or OpenType (.otf) file, or it is the name of the font, in which case the system font paths will be searched to find the font file. This typeface will be used for roman characters (Extended Latin, that is, European languages).
styleIgnored if typeface is a file, but will be used to qualify the font if a system font name is used. Will be applied to any additional language or code point typefaces.
point_sizeThe point size (NOT pixel size) of the font. Will be applied to any additional language or code point typefaces. A size of 0 indicates the default size.

Member Function Documentation

◆ AddTypefaceForCodePoints()

void open3d::visualization::gui::FontDescription::AddTypefaceForCodePoints ( const char *  typeface,
const std::vector< uint32_t > &  code_points 
)

Adds specific code points from the typeface. This is useful for selectively adding glyphs, for example, from an icon font.

◆ AddTypefaceForLanguage()

void open3d::visualization::gui::FontDescription::AddTypefaceForLanguage ( const char *  typeface,
const char *  lang 
)

Adds code points outside Extended Latin from the specified typeface. Supported languages are: "en" (English) [this was already added in the constructor] "ja" (Japanese) "ko" (Korean) "th" (Thai) "vi" (Vietnamese) "zh" (Chinese, 2500 most common characters, 50 MB per window) "zh_all" (Chinese, all characters, ~200 MB per window) All other languages will be assumed to be Cyrillic. Note that generally fonts do not have CJK glyphs unless they are specifically a CJK font, although operating systems generally use a CJK font for you. We do not have the information necessary to do this, so you will need to provide a font that has the glyphs you need. In particular, common fonts like "Arial", "Helvetica", and SANS_SERIF do not contain CJK glyphs.
