◆ _compressPageData()

static MLErrorCode ml::MLImageFormatTools::_compressPageData	(	DataCompressor *	compressor,
		SubImage &	dataSubImg,
		MLint &	dstBufSize )

staticprotected

Compresses data of a subimage.

Parameters

compressor	Instance of MLDataCompressor used for compression of page data if non NULL. If NULL the page data is not compressed.
dataSubImg	Subimage containing the data to compress. Its data chunk is (only) overwritten with compressed data on effective and successful compression.
dstBufSize	Size of compressed data or 0 if no compression took place (because it was ineffective or no compressor was available).

Returns: ML_RESULT_OK on success and if data was not compressed. On failure an error describing code is returned.

◆ _decompressPageData()

static MLErrorCode ml::MLImageFormatTools::_decompressPageData	(	const MLImageFormatInfos &	infos,

		const size_t	expectedSizeInBytes,
		MLuint8 *&	loadedPage,
		bool &	isLossy )

staticprotected

Decompress and replace data given as pointer in loadedPage.

Parameters

infos	The information structure about the current working file. Its settings must fit with corresponding settings of inputPagedImg.
savedPageSizeInBytes	Must be exactly the size of the compressed memory buffer given in loadedPage.
expectedSizeInBytes	The expected size of the uncompressed memory.
loadedPage	must be a valid pointer to loaded and compressed page data. It will be freed with MLFree() and replaced with decompressed data if decompression takes place. On failure is also could be returned as NULL.
isLossy	will be overwritten to false if data was lossless compressed, otherwise true.

◆ _destroyFileProperties()

static MLErrorCode ml::MLImageFormatTools::_destroyFileProperties ( MLImageFormatInfos *& infos )

staticprotected

Destroys the MLImageFileInfo object and resets the pointer to NULL.

Returns ML_RESULT_OK on success or on failure an MLErrorCode describing the problem.

◆ _loadFileProperties()

static MLErrorCode ml::MLImageFormatTools::_loadFileProperties ( MLImageFormatInfos & infos )

staticprotected

Reads all information from the file given by fileHandle in infos and stores it the returned information object.

Parameters

infos infos must be a valid information structure created by open() on the file to read from.

Returns: ML_RESULT_OK on success or on failure an MLErrorCode describing the problem.

◆ _loadPage()

static MLErrorCode ml::MLImageFormatTools::_loadPage	(	const MLImageFormatInfos &	infos,
		MLint	pageId,
		SubImage &	pageBuf )

staticprotected

Read page given by id pageId into memory handled by pageBuf.

pageBuf must provide enough data for a full loaded page extent. Returns ML_RESULT_OK on success and another MLErrorCode otherwise. Requires that infos is valid, that it describes a file opened for reading and that all passed parameters (index table and tag list) are already read from that open file. It also requires that data type and box of pageBuf are set correctly. Note that the loading process may cause that the page box is modified to match the valid image region.

◆ _saveIndexTableAndPages()

static MLErrorCode ml::MLImageFormatTools::_saveIndexTableAndPages	(	MLImageFormatInfos &	infos,
		const SubImageBox &	box,
		PagedImage *	inputPagedImg,
		const SubImage *	inputSubImg,
		MLImageFormatNotifyCB *	callback,
		void *	userData,
		const ScaleShiftData &	scaleShiftData,
		bool	replaceAreaToSave,
		MLuint32	saveModeBits,
		MLdouble *	saveTime = nullptr,
		MLdouble *	prepTime = nullptr )

staticprotected

Save or overwrite pages overlapping areaToSave of inputPagedImg.

Note that only one of both pointers, inputPagedImg and inputSubImg, may be non NULL to define a unique source for the data to be written. Whichever is used - its data type must fit the setting in info and it must contain the box to be saved if box is non empty.

Parameters

infos	The information structure about the current working file. Its settings must fit with corresponding settings of inputPagedImg.
box	box describing the pages to be written, pages outside are not stored and marked as pages filled with defaultVoxelValue. Regions outside but inside of pages are filled with defaultVoxelValue. An empty box is considered as full image.
inputPagedImg	The paged image from where page data and/or image properties are taken to be stored. It must be up to date.
inputSubImg	The subimage from which page data and image properties are taken to be stored. It must be up to date.
callback	Function to be called on different processing and storage to notify and/or break the storage process. May be passed as NULL pointer and is ignored then.
userData	Application data passed to the callback function or NULL not needed.
scaleShiftData	Defines a linear transformation to be applied on data from inputPagedImg or inputSubImg before saving it on disc. Default is the identical transformation.
replaceAreaToSave	if true then the area to save is overwritten without changes of other file contents outside that region. If false then all pages are overwritten, even if outside the areaToSave. Note that true also may cause that partially written pages are loaded and rewritten with changes. It also may cause a fragmentation of the file if written pages do not fit into their former data gap. Default is false.
saveTime	Ignored if NULL, otherwise it returns the time needed for pure data saving without data preparation such as data reordering or compression.
prepTime	Ignored if NULL, otherwise it returns the time needed for data preparation such as reordering or compression without saving.
saveModeBits	Bit combination setting special save options: See SaveModeBits for possible options.

Returns: ML_RESULT_OK on success or on failure an MLErrorCode describing the problem.

◆ _savePage()

static MLErrorCode ml::MLImageFormatTools::_savePage	(	MLImageFormatInfos &	infos,
		const MLint	pageId,
		const bool	isOutsideAreaToSave,
		const MLTypeData *	defaultVoxelPtr,
		const SubImage &	subImgToSave,
		const bool	replaceOnlyWrittenPageIds,
		const MLuint32	saveModeBits,
		TimeCounter &	saveTimer,
		MLdouble &	saveTime,
		TimeCounter &	calcTimer,
		MLdouble &	calcTime )

staticprotected

Store the page subImgToSave in file given by infos and update the corresponding entry in the index table.

Note that pages outside the areaToSave are not stored - only the index table entries are updated. In this case subImgToSave does not need to have a valid data pointer. If saveModeBits allow storing partial pages then subImgToSave will be reduced to

Parameters

infos	File information structure from file open in writable and binary mode.
pageId	id of page to be stored.
isOutsideAreaToSave	true if page is outside the area to save, false otherwise. If true then only entries of the index table are updated.
defaultVoxelPtr	Pointer to value used for non stored values outside box and for stored page regions outside box.
subImgToSave	The page data to be saved. It must be up to date.
replaceOnlyWrittenPageIds	if true then entries of the index table are updated only if isOutsideAreaToSave is false. Otherwise all page ids are updated, even those whose pages are not stored.
saveModeBits	Bit combination setting special save options: See SaveModeBits for possible options.
saveTimer	TimeCounter used to measure the time needed for pure data saving without data preparation such as data reordering or compression.
saveTime	The time measured with saveTimer is added to this value.
calcTimer	TimeCounter used to measure the time needed for data processing such as compression, reordering and checksums without saving time.
calcTime	The time measured with calcTimer is added to this value.

Returns: ML_RESULT_OK on success or on failure an MLErrorCode describing the problem.

◆ calcCheckSum()

static MLuint32 ml::MLImageFormatTools::calcCheckSum	(	const void *	dataPtr,
		size_t	numBytes,
		size_t	voxSize )

static

Calculates a 24 bit check sum for the data given by dataPtr.

All values of each byte in the data are multiplied with their byte position and added to the sum. The checkSum calculation traverses voxel data endianess independent; therefore it assumes that the data is in local machine endianess. Thus the calculated sum will be the same on machines with other endianess.

Parameters

dataPtr	points to the chunk of data to be check-summed.
numBytes	is the whole number of bytes to be included in checksum.
voxSize	is the size of a voxel in bytes stored in the data. numBytes must be divisible exactly by voxSize.

◆ close()

static MLErrorCode ml::MLImageFormatTools::close ( MLImageFormatInfos *& infos )

static

Closes an open file.

Closing a non open file causes an error.

Parameters

infos A pointer to a valid information structure created by open() on the file to be closed.

Returns: ML_RESULT_OK on success or another code describing the problem. Pointer to infos is always reset to NULL.

◆ getTile()

static MLErrorCode ml::MLImageFormatTools::getTile	(	const MLImageFormatInfos &	infos,
		SubImage &	subImgToFill,
		bool	useFileDataType,
		bool	useFileRegion,
		const ScaleShiftData &	scaleShiftData )

static

Loads a subimage from the specified file and returns an MLErrorCode describing success or failure.

Previous settings of the subimage are overwritten. Subimage memory will be (re)allocated if its pointer is NULL or if memory denoted by box and data type is too small, otherwise memory will be reused.

Parameters

infos	infos must be a valid information structure created by open() on the file to read from.
subImgToFill	The subimage to be manage the loaded data.
useFileDataType	If true then the data type of the stored file is used; if false the data type of subImgToFill is used. Default is to use the data type of the subimage.
useFileRegion	If true then the extent of the file is loaded as tile and the subImgToFill box is overwritten; if false the region of subImgToFill is used. Default is to use the region of the subimage.
scaleShiftData	Specifies scale factor and offset for loaded data. If not passed the data will not be rescaled.

Returns: An MLErrorCode describing the success or failure of the operation and ML_RESULT_OK on success.

Note that this routine will use subImgToFill.free() and subImgToFill.allocate() to (re)allocate the data if its size is not enough. Be sure that eventually set subimage data was also allocated with subImgToFill.allocate() or MLAllocateMemory (and not with new or so) to avoid collisions of memory managers. Automatically opens the file if still not done and closes it after operation if autoClose is true (the default).

◆ open() [1/2]

static MLErrorCode ml::MLImageFormatTools::open	(	MLImageFormatInfos *&	infos,
		const std::string &	fileName,
		bool	truncate = false,
		const std::string &	compressorName = "",

		const MLImageFormatTagList &	userTagList = MLImageFormatTagList::getDefaultEmptyTagList(),
		const MLImageFormatTagList &	privateTagList = MLImageFormatTagList::getDefaultEmptyTagList(),
		const std::string &	defaultVoxelValue = "0",
		bool	rewritable = true,
		bool	suppressReadCheckSumTests = false )

static

Opens a file in binary mode returning a descriptor for the opened file.

Parameters

infos	A NULL MLImageFormatPointer which is initialized with an object with open file information.
fileName	is the UTF8 encoded path and name of the file to be opened.
truncate	opens the file for new or overwriting the file and discarding the previous contents if true. Reopens an exiting file for reading and manipulation if false.
compressorName	name of DataCompressor used for data compression if not "" (the default).
compressionTagList	is the list of MLImageFormatTags storing arguments for the compressor passed in compressor argument. Ignored if compressor is NULL.
userTagList	is the list of MLImageFormatTags storing user information.
privateTagList	is the list of MLImageFormatTags storing private information.
defaultVoxelValue	is the string value used for all non existing pages and not written pages to define a background value for sparsely written image.
rewritable	If truncate is false then this flag decides whether the file is opened as read only or as a rewritable file. Default is true which means that opening is done in read-write mode. This flag is ignored if truncate is true.
suppressReadCheckSumTests	If true then checksum tests are disabled while reading page data to gain maximum load performance; the default is off, because this is not recommended. Not allowed if the file is created or modified.

Returns: a new MLImageFormatInfo structure with a valid file handle on success or NULL on failure. On failures the file is closed.
