T\-Output\-Image\-::\-I\-O\-Pixel\-Type $>$$>$class itk\-::\-Image\-File\-Reader\-K\-W$<$ T\-Output\-Image, Convert\-Pixel\-Traits $>$} Data source that reads image data from a single file. This source object is a general filter to read data from a variety of file formats. It works with a Image\-I\-O\-Base subclass to actually do the reading of the data. Object factory machinery can be used to automatically create the Image\-I\-O\-Base, or the Image\-I\-O\-Base can be manually created and set. Note that this class reads data from a single file; if you wish to read data from a series of files use Image\-Series\-Reader. T\-Output\-Image is the type expected by the external users of the filter. If data stored in the file is stored in a different format then specified by T\-Output\-Image, than this filter converts data between the file type and the external expected type. The Convert\-Traits template argument is used to do the conversion. A Pluggable factory pattern is used this allows different kinds of readers to be registered (even at run time) without having to modify the code in this class. Normally just setting the File\-Name with the appropriate suffix is enough to get the reader to instantiate the correct Image\-I\-O and read the file properly. However, some files (like raw binary format) have no accepted suffix, so you will have to manually create the Image\-I\-O instance of the write type. \begin{DoxySeeAlso}{See Also}

Often this is created via the object factory mechanism that determines whether a particular Image\-I\-O can read a certain file. This method provides a way to get the Image\-I\-O instance that is created. Or you can directly specify the Image\-I\-O to use to read a particular file in case the factory mechanism will not work properly (e.\-g., unknown or unusual extension). \hypertarget{classitk_1_1_image_file_reader_k_w_a68e1c6d1289530941de1424844f481b5}{\index{itk\-::\-Image\-File\-Reader\-K\-W@{itk\-::\-Image\-File\-Reader\-K\-W}!Test\-File\-Existance\-And\-Readability@{Test\-File\-Existance\-And\-Readability}} \index{Test\-File\-Existance\-And\-Readability@{Test\-File\-Existance\-And\-Readability}!itk::ImageFileReaderKW@{itk\-::\-Image\-File\-Reader\-K\-W}} \subsubsection[{Test\-File\-Existance\-And\-Readability}]{\setlength{\rightskip}{0pt plus 5cm}template$<$typename T\-Output\-Image , typename Convert\-Pixel\-Traits $>$ void {\bf itk\-::\-Image\-File\-Reader\-K\-W}$<$ T\-Output\-Image, Convert\-Pixel\-Traits $>$\-::Test\-File\-Existance\-And\-Readability ( \begin{DoxyParamCaption} {} \end{DoxyParamCaption} )\hspace{0.3cm}{\ttfamily [protected]}}}\label{classitk_1_1_image_file_reader_k_w_a68e1c6d1289530941de1424844f481b5} Test whether the given filename exist and it is readable, this is intended to be called before attempting to use Image\-I\-O classes for actually reading the file.
