Header:	#include <QSafeLayoutFileReader>
Since:	QtSafeRenderer 1.0
Inherits:	SafeRenderer::QSafeLayout

This class was introduced in QtSafeRenderer 1.0.

	QSafeLayoutFileReader(const SafeRenderer::qchar const filenameArg*)
	QSafeLayoutFileReader()

virtual const SafeRenderer::QSafeByteArray readDataFromFile(const SafeRenderer::qchar *const filenameArg) override

The QSafeLayoutFileReader class reads the layout data from a file.

Constructs a safe layout file reader that reads the layout data from the filenameArg.

The full path of the file can given to the filenameArg parameter. The bitmap data files must be located in the same path with the layout data file.

In case of a failure, one of the following exceptions are thrown:

Constant	Description
`SafeRenderer::QSafeBitmapFileReader::BitmapFileReaderException::TooMany`	The number of bitmaps exceeds the Constraints::MAX_AMOUNT_OF_BITMAPS value.
`SafeRenderer::QSafeFile::FileException::SeekError`	Seek failed on opening the file. For example, the root cause for the error can be a filesystem error or a file that is a pipe.
`SafeRenderer::QSafeLayout::LayoutException::DataSizeMismatch`	Layout file's size is more than buffer's size.
`SafeRenderer::QSafeFile::FileException::ReadError`	The requested number of bytes can not be read from the opened file.
`SafeRenderer::QSafeLayout::LayoutException::SizeErrorWidth`	The width of the layout size too long.
`SafeRenderer::QSafeLayout::LayoutException::SizeErrorHeight`	The height of the layout size too long.
`SafeRenderer::QSafeLayout::LayoutException::DataSizeMismatch`	The layout file size is not multiple of the layout data size or layout data size is too small, or has too many layouts
`SafeRenderer::QSafeLayout::LayoutException::InvalidLayoutVersion`	Layout version is not supported.
`SafeRenderer::QSafeLayout::LayoutException::CheckSumFailed`	Layout checksum value does not match with the data checksum.
`SafeRenderer::QSafeLayout::LayoutException::TooLongFilename`	Bitmap's filename was too long to fit in buffer.

Constructs a safe layout file reader.

Reimplements: QSafeLayout::readDataFromFile(const SafeRenderer::qchar *const filenameArg).
