Member Function Documentation

◆ Capture() [1/2]

void TGLOutput::Capture ( TGLViewer & viewer)
static

this function used by gl-viewer, embedded into pad

Definition at line 198 of file TGLOutput.cxx.

◆ Capture() [2/2]

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

Definition at line 43 of file TGLOutput.cxx.

◆ 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
