## Detailed Description

This class can be used to do output preview. Output preview is to preview color separations and test different color profiles. Before use this class, please ensure function Library.SetDefaultICCProfilesPath has been called successfully; otherwise unexpcted error or result may occur when this class is being used to do output preview. Currently, this feature is not supported on the Linux ARM and Mac ARM platform.

## Member Function Documentation

## ◆ constructor()

OutputPreview.constructor | ( | pdf_doc |  | ) |

Constructor, with parameters.

Parameters

  [in] | pdf_doc | A valid PDF document object.

## ◆ EnableSimulateOverprint()

OutputPreview.EnableSimulateOverprint | ( | is_to_simulate_overprint |  | ) |

Set the flag to decide whether to enable simulate overprint.

If this function is not called, default value true will be used.

Parameters

  [in] | is_to_simulate_overprint | true means to simulate overprinting. false means not to simulate overprinting.

Returns
  None.

## ◆ GeneratePreviewBitmap()

OutputPreview.GeneratePreviewBitmap | ( | page | ,
|  | matrix | ,
|  | renderer |
| ) |  |

Generate the output preview bitmap for a PDF page.

This function will render target PDF page with flags and options specified in input renderer and settings of current output preview object, and then return the final output preview bitmap. Rendering process in this function will not affect input renderer.
Please ensure function OutputPreview.SetSimulationProfile has been called successfully; otherwise this function will throw e_ErrUnsupported.

Parameters

  [in] | page | A valid PDF page object. This PDF page should have been parsed.
  [in] | matrix | The transformation matrix used for rendering, which is usually returned by function PDFPage.GetDisplayMatrix.
  [in] | renderer | A valid renderer object.

Returns
  A bitmap which represents the output preview result.

## ◆ GetPlates()

OutputPreview.GetPlates | ( | colorant_type |  | ) |

Get Separations plates.

If to get plates of process colorant type, please ensure function OutputPreview.SetSimulationProfile has been called successfully; otherwise no plate of process colorant type will be retrieved.

Parameters

  [in] | colorant_type | Colorant type. Please refer to values starting from OutputPreview.e_ColorantTypeProcess and this should be one of these values.

Returns
  A string array which represents plate names.

## ◆ GetSpotPlateColor()

OutputPreview.GetSpotPlateColor | ( | plate_name |  | ) |

Get the color value of a plate.

This function is only useful for a plate in spot colorant type.

Parameters

  [in] | plate_name | Plate name. This can be retrieved form the returned string array of function OutputPreview.GetPlates.

Returns
  RGB color of the specified plate.

## ◆ IsChecked()

OutputPreview.IsChecked | ( | plate_name |  | ) |

Check whether a plate is checked or not.

For a newly constructed output preview object, all the plates are not checked.

Parameters

  [in] | plate_name | Plate name. This can be retrieved from the returned string array of function OutputPreview.GetPlates.

Returns
  true means the plate is checked, while false means the plate is not checked.

## ◆ IsEmpty()

OutputPreview.IsEmpty | ( |  | ) |

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.

Returns
  true means current object is empty, while false means not.

## ◆ SetCheckStatus()

OutputPreview.SetCheckStatus | ( | plate_name | ,
|  | to_check |
| ) |  |

Set the check status for a plate.

Parameters

  [in] | plate_name | Plate name. This can be retrieved from the returned string array of function OutputPreview.GetPlates.
  [in] | to_check | Check status: true means to check the plate, while false means not to check the plate.

Returns
  None.

## ◆ SetShowType()

OutputPreview.SetShowType | ( | show_type |  | ) |

Set show type.

If no show type is set to current object, value OutputPreview.e_ShowAll will be used by default when function OutputPreview.GeneratePreviewBitmap is called.

Parameters

  [in] | show_type | Show type. Please refer to values starting from OutputPreview.e_ShowAll and this should be one of these values.

Returns
  None.

## ◆ SetSimulationProfile()

OutputPreview.SetSimulationProfile | ( | icc_profile_path |  | ) |

Set simulation ICC profile file path.

If the color space of input ICC profile file is not one of RGB/Gray/CMYK, this function will throw e_ErrUnsupported.
This function should be called successfully before calling function OutputPreview.GeneratePreviewBitmap.

Parameters

  [in] | icc_profile_path | File path for an ICC profile which is to be used as simulation profile for output preview.

Returns
  None.
