Member Function Documentation

void firevision::ColormapFile::add_colormap ( Colormap colormap)
void firevision::ColormapFile::clear ( void  ) [virtual]

Clear internal storage.

All internal data is deleted.

Reimplemented from firevision::FireVisionDataFile.

Definition at line 238 of file cmfile.cpp.

ColormapFile::ColormapBlockVector * firevision::ColormapFile::colormap_blocks ( )

Get colormap blocks.

Returns:
vector of colormap blocks

Definition at line 134 of file cmfile.cpp.

References firevision::FireVisionDataFile::blocks().

std::string firevision::ColormapFile::compose_filename ( const std::string  format) [static]

Compose filename.

In the format g is replaced with the hostname.

Parameters:
formatformat for the filename
Returns:
filename

Definition at line 220 of file cmfile.cpp.

Colormap * firevision::ColormapFile::get_colormap ( )

Get a freshly generated colormap based on current file content.

This returns an instance of a colormap that uses all current blocks of this instance. Currently it only supports file which contain a valid YuvColormap. This means that it has d blocks of YUV type. d is the depth and must fulfill d=2^n with n from [1,8]. It can throw any exception that the YuvColormap ctor can throw.

Returns:
instance of colormap. You must delete it after you are done with it.

uint16_t firevision::ColormapFile::get_depth ( )

Get depth of colormap.

Returns:
depth

uint16_t firevision::ColormapFile::get_height ( )

Get height of colormap.

Returns:

uint16_t firevision::ColormapFile::get_width ( )

Get width of colormap.

Returns:
width

bool firevision::ColormapFile::is_colormap_file ( const char *  filename) [static]

Check if given file is a colormap file.

Parameters:
filenamename of file to check
Returns:
true if file is a colormap file, false otherwise
