Namespace: SautinSoft
Assembly: SautinSoft.PdfFocus (in SautinSoft.PdfFocus.dll) Version: 2024.3.28
Syntax
public PdfFocuseImageFormat EmbeddedImagesFormat { get; set; }

Property Value

PdfFocuseImageFormat
Remarks
  • eImageFormat.Auto - In this case the images will be stored in their original format. In other words, the JPEG-images will be stored using Jpeg codec, the all others as PNG.

  • eImageFormat.Png - Force to convert all images into Png format.

  • eImageFormat.Jpeg - Force to convert all images into Jpeg format. Be careful: using Jpeg for images you can reduce the PDF size, but could lose the transparency.

Using this property together with the JpegQuality allows you to reduce to size of the output document.
