TIGER

Tiger (Texture/Image GenEatoR) loads a set of images and applies a filter multiple times. The result of the filter, can be descriped by the equation

$$ \vec{y_{k+1}}(x,y) = \vec{f}(x,y,\vec{y_k}(x,y),\vec{p}) $$

Command line options

This is a summary of all command line options. Values inside square brackets are optional. For details on how to type values, see Common types below.

--help[=string] Prints usage information to either stdout, or to the chosen file.

--example[=string] Generates source code for an example filter. The output is printed to either stdout, or to the chosen file.

--filter=string Specifies the filter file. The filter is either a shared object, or C++ source file. A template filter can be extracted with the --example option. When a C++ source file is specified, it will be compiled into a shared object stored. The location of that object is controlled by the option --objdir.

--objdir=string Specifies where to store any copiled binary, relative to the working directory.

--params[=Parameter,...] Sets filter parameters. This is the content of $\vec{p}$ in the equation above.

--params-list[=string] Lists all parameters availible for filter

--channels-list[=string] Lists all channel names used by filter

--init=Channel mapping,... Selects initial images. These images determines $\vec{y_{0}}$ in the equation above.

--dest=Channel mapping,... Selects output images

--iterations=unsigned int Selects the number of iterations to apply the filter

Common types

Channel mapping := [Channel:Filename] A Channel mapping maps a channel to a given file. Use --channels-list to see a list of availible channels.

Parameter := [Name:Value] Parameters control the algorithm used by filter. Use --params-list to see a list of parameters availible.

string An UTF-8 encoded string

unsigned int An integer in the range [0, 4294967295]
