Class FlattenTransparencyParams

java.lang.Object
com.datalogics.PDFL.FlattenTransparencyParams
public class FlattenTransparencyParams extends Object
Represents control parameters for flattening transparencies within a PDF file. Class that represents control parameters for flattening transparencies within a PDF file. PDF files can hold objects that are stacked, and that are partially or fully transparent. This means that these objects can blend in various ways with objects behind them. With a stacked set of transparent graphics or images in a PDF file, each one contributing to the final result that appears on the page. One or more graphics images presented together in a stack is referred to as a transparency group. With a stack of transparent images, the final colors shown are the result of blending the colors of all of the overlapping objects. Flatten Transparency merges a stack of transparent objects or graphics into a single image on the PDF page.

Flattening images in a PDF file is generally necessary before you can send the document to a printer. The flattening process simplifies the PDF file and may make it smaller as well.

    • FlattenTransparencyParams

      public FlattenTransparencyParams()
      Set up default parameters for flattening transparency.

      Parameters:
      UseTextOutlines - Output text outlines instead of native text. Default is true.
      ConvertStrokesToOutlines - Convert strokes to outlines. Default is true.
      ClipComplexRegions - Ensure that boundaries between vector and rasterized artwork fall along object paths. Default is true.
      InternalDPI - Resolution for flattening the interior of an atomic region. Default is 150.
      ExternalDPI - Resolution for flattening edges of atomic regions. Default is 300.
      PreserveOverprint - Attempt to preserve overprint. Default is true.
      Quality - The percentage of vector information that is to be preserved. Default is 100.

      public FlattenTransparencyParams(boolean UseTextOutlines, boolean ConvertStrokesToOutlines, boolean ClipComplexRegions, int InternalDPI, int ExternalDPI, boolean PreserveOverprint, int Quality)
      Set up parameters for flattening transparency.

      Parameters:
      UseTextOutlines - If true, output text outlines instead of native text.
      ConvertStrokesToOutlines - If true, convert strokes to outlines.
      ClipComplexRegions - If true, ensure that boundaries between vector and rasterized artwork fall along object paths.
      InternalDPI - Resolution for flattening the interior of an atomic region. Range is 1 to 9600.
      ExternalDPI - Resolution for flattening edges of atomic regions. Range is 1 to 1200.
      PreserveOverprint - If true, attempt to preserve overprint.
      Quality - The percentage of vector information that is to be preserved. Lower values will cause higher rasterization of vectors. Range is 0 to 100.
