Member Function Documentation

◆ Capture() [1/2]

void TGLOutput::Capture ( TGLViewer &  viewer)
static

this function used by gl-viewer, embedded into pad

Definition at line 197 of file TGLOutput.cxx.

◆ Capture() [2/2]

Bool_t TGLOutput::Capture ( TGLViewer &  viewer,
EFormat  format,
const char *  filePath = 0 
)
static

Capture viewer to file.

Arguments are:

  • 'viewer' - viewer object to capture from
  • 'format' - output format - only postscript types presently. One of kEPS_SIMPLE, kEPS_BSP, kPDF_SIMPLE or kPDF_BSP See TGLOutput::CapturePostscript() for meanings
  • 'filePath' - file output name. If null defaults to './viewer.eps' or './viewer.pdf' depending on format requested

Note : Output files can be large and take considerable time (up to mins) to generate

◆ CapturePostscript()

Bool_t TGLOutput::CapturePostscript ( TGLViewer &  viewer,
EFormat  format,
const char *  filePath 
)
staticprivate

Capture viewer to postscript file.

Arguments are:

  • 'viewer' - viewer object to capture from
  • 'format' - output format
    • kEPS_SIMPLE - lower quality EPS
    • kEPS_BSP - higher quality EPS
    • kPDF_SIMPLE - lower quality PDF
    • kPDF_BSP - higher quality PDF
  • 'filePath' - file output name. If null defaults to './viewer.eps' or './viewer.pdf' depending on format requested
