Functions
wxBitmap	LoadSVG (const wxString filename, const unsigned int width, const unsigned int height, wxBitmap *default_bitmap, bool use_cache)
	Load SVG file and return it's bitmap representation of requested size In case file can't be loaded an empty bitmap of desired size or a provided default bitmap is returned.

int	str_ends_with (const char str, const char suffix)

unsigned int	get_px_length (const char *val)

bool	SVGDocumentPixelSize (const wxString filename, unsigned int &width, unsigned int &height)
	Return the size of the SVG document in standard 96 DPI pixels https://developer.mozilla.org/en-US/docs/Web/SVG/Content_type#length Percentage, em and ex make no sense without being able to relate them to something, so we just return the numerical value as we do for px.

unsigned int	SVGPixelsToDisplay (unsigned int svg_px)
	Recalculate the length in standard 96 DPI pixels to actual display pixels.

wxBitmap	LoadSvgStdIcon (const std::string &svg_file, const wxWindow *w, bool touch)
	Load an svg icon from standard path, roughly scaled to the height of a char.

Function Documentation

◆ get_px_length()

unsigned int get_px_length ( const char * val )

Definition at line 123 of file svg_utils.cpp.

◆ LoadSVG()

wxBitmap LoadSVG	(	const wxString	filename,
		const unsigned int	width,
		const unsigned int	height,
		wxBitmap *	default_bitmap,
		bool	use_cache
	)

Load SVG file and return it's bitmap representation of requested size In case file can't be loaded an empty bitmap of desired size or a provided default bitmap is returned.

Definition at line 59 of file svg_utils.cpp.

◆ LoadSvgStdIcon()

wxBitmap LoadSvgStdIcon	(	const std::string &	svg_file,
		const wxWindow *	w,
		bool	touch
	)

Load an svg icon from standard path, roughly scaled to the height of a char.

Parameters

touch If true ensures icon is "big enough" for touch screens

Definition at line 207 of file svg_utils.cpp.

◆ str_ends_with()

int str_ends_with	(	const char *	str,
		const char *	suffix
	)

Definition at line 108 of file svg_utils.cpp.

◆ SVGDocumentPixelSize()

bool SVGDocumentPixelSize	(	const wxString	filename,
		unsigned int &	width,
		unsigned int &	height
	)

Return the size of the SVG document in standard 96 DPI pixels https://developer.mozilla.org/en-US/docs/Web/SVG/Content_type#length Percentage, em and ex make no sense without being able to relate them to something, so we just return the numerical value as we do for px.

Definition at line 148 of file svg_utils.cpp.

◆ SVGPixelsToDisplay()

unsigned int SVGPixelsToDisplay ( unsigned int svg_px )

Recalculate the length in standard 96 DPI pixels to actual display pixels.

Definition at line 202 of file svg_utils.cpp.
