Functions

GenImgName (line 373)

Utility function to generate an image name based on the filename we

are running from AND assuming we use auto detection of graphic format (top level), i.e it is safe to call this function from a script that uses JpGraph

void GenImgName ()

sign (line 364)

Usefull mathematical function

void sign (mixed $a)
