Constructor & Destructor Documentation

wxRichTextImageBlock::wxRichTextImageBlock ( )

Constructor.

wxRichTextImageBlock::wxRichTextImageBlock ( const wxRichTextImageBlock & block )

Copy constructor.

virtual wxRichTextImageBlock::~wxRichTextImageBlock ( )

virtual

Member Function Documentation

void wxRichTextImageBlock::Clear ( )

Clears the block.

void wxRichTextImageBlock::Copy ( const wxRichTextImageBlock & block )

Copy from block.

virtual bool wxRichTextImageBlock::DoMakeImageBlock	(	const wxImage &	image,
		wxBitmapType	imageType
	)

virtual

Makes the image block.

unsigned char* wxRichTextImageBlock::GetData ( ) const

inline

Returns the raw data.

size_t wxRichTextImageBlock::GetDataSize ( ) const

inline

Returns the data size in bytes.

wxString wxRichTextImageBlock::GetExtension ( ) const

Gets the extension for the block's type.

wxBitmapType wxRichTextImageBlock::GetImageType ( ) const

inline

Returns the image type.

void wxRichTextImageBlock::Init ( )

Initialises the block.

bool wxRichTextImageBlock::IsOk ( ) const

inline

Returns true if the data is non-NULL.

bool wxRichTextImageBlock::Load ( wxImage & image )

virtual bool wxRichTextImageBlock::MakeImageBlock	(	const wxString &	filename,
		wxBitmapType	imageType,
		wxImage &	image,
		bool	convertToJPEG = `true`
	)

virtual

Load the original image into a memory block.

If the image is not a JPEG, we must convert it into a JPEG to conserve space. If it's not a JPEG we can make use of image, already scaled, so we don't have to load the image a second time.

virtual bool wxRichTextImageBlock::MakeImageBlock	(	wxImage &	image,
		wxBitmapType	imageType,
		int	quality = `80`
	)

virtual

Make an image block from the wxImage in the given format.

virtual bool wxRichTextImageBlock::MakeImageBlockDefaultQuality	(	const wxImage &	image,
		wxBitmapType	imageType
	)

virtual

Uses a const wxImage for efficiency, but can't set quality (only relevant for JPEG)

bool wxRichTextImageBlock::Ok ( ) const

inline

		size_t	size
	)

static
