Detailed Description

An ImageIO plugin supporting reading and writing TIFF (RGB and LogLuv).

Note that currently only writing of the LogLuv format is supported. If the image is in RGB mode, a standard RGB TIFF is written out. In XYZ mode, the XYZ values are given directly to the libtiff library and the image is written out in the 32-bit LogLuv format.

Todo:

Add support for reading LogLuv TIFF.

Member Function Documentation

bool TIFFIO::supportsExtension (  const char *  extension  )  [virtual]

Determine if this plugin supports the given extension. Parameters: [in]  extension  A lowercase string extension (e.g. "tif") Returns: True if the plugin supports this extension, false otherwise. Implements ImageIO.

void TIFFIO::registerExtensions (  DynArray< std::string > &  extensions  )  [virtual]

Build a list of all the extensions this plugin can support Parameters: [out]  extensions  A DynArray to hold the list of extensions. Returns: The return is by reference (extensions parameter). Implements ImageIO.

bool TIFFIO::readImage (  const char *  filename, Image *&  result )  [virtual]

Given an Image and a filename, try to create an Image. The system will guarantee that the extension is supported by this plugin. Parameters: [in]  filename  The name of the file to read from. [out]  result  The resulting Image. Memory has to be allocated. Returns: readImage returns true if everything went smoothly. Implements ImageIO.

bool TIFFIO::writeImage (  const char *  filename, const Image *  image )  [virtual]

Given an Image and a filename, try to write the Image to disk. The system will guarantee that the extension is supported by this plugin. Parameters: [in]  filename  The name of the file to write to. [in]  image  The Image data to write out. Returns: writeImage returns true if everything went smoothly. Implements ImageIO.
