Function Documentation

◆ libPGFVersion()

DIGIKAM_EXPORT QString Digikam::PGFUtils::libPGFVersion ( )

Return a libpgf version string

Referenced by Digikam::LibsInfoDlg::LibsInfoDlg().

◆ loadPGFScaled()

DIGIKAM_EXPORT bool Digikam::PGFUtils::loadPGFScaled	(	QImage &	img,
		const QString &	path,
		int	maximumSize
	)

Load a reduced version of PGF file

◆ readPGFImageData()

DIGIKAM_EXPORT bool Digikam::PGFUtils::readPGFImageData	(	const QByteArray &	data,
		QImage &	img,
		bool	verbose = `false`
	)

PGF image data to QImage using memory stream. NOTE: Only use this method to manage PGF thumbnails stored in database.

◆ writePGFImageData()

DIGIKAM_EXPORT bool Digikam::PGFUtils::writePGFImageData	(	const QImage &	image,
		QByteArray &	data,
		int	quality,
		bool	verbose = `false`
	)

QImage to PGF image data using memory stream.

Parameters

quality set compression ratio: 0 => lossless compression, as PNG. 1 => Not loss less compression, wavelets based... 2 => ... 3 => ... 4 => Same compression ratio near than JPEG quality=85. Image quality is valid for thumbnails. >= 5 => provide artifacts due to down-sampling. Do not use it... NOTE: Only use this method to manage PGF thumbnails stored in database.

◆ writePGFImageDataToStream()

bool Digikam::PGFUtils::writePGFImageDataToStream	(	const QImage &	image,
		CPGFStream &	stream,
		int	quality,
		UINT32 &	nWrittenBytes,
		bool	verbose
	)

◆ writePGFImageFile()

DIGIKAM_EXPORT bool Digikam::PGFUtils::writePGFImageFile	(	const QImage &	image,
		const QString &	filePath,
		int	quality,
		bool	verbose = `false`
	)

QImage to PGF image data using file stream. Uses same params than writePGFImageData() excepted 'filePath' which is PGF target file path.
