/**\brief Run a regression test with an explicitly-provided image filename.
|

|
*
|
||
|
|
* Unlike the traditional C++ image-based test macro (vtkRegressionTestImage),
|
||
|
|
* this templated function accepts the name of a baseline image.
|
||
|
|
* It uses the existing vtkTesting infrastructure to expand the image name
|
||
|
|
* into a full path by replacing the implied filename component of the valid
|
||
|
|
* image (specified with "-V" on the command line) with the given \a img
|
||
|
|
* value. The directory portion of the valid image path preceding is untouched.
