Parameters

page

Type: pdftron.PDFPage
The page to export.

filename

Type: SystemString
The path and filename where to export the image. The filename should include the extension suffix (i.e. MyImage.bmp).

format

Type: SystemString
The file format of the output image. Currently supported formats are:

• "RAW" : RAW format. There are four possibilities: e_rgba - if transparent and color page; e_gray_alpha - if transparent and gray page; e_rgb - if opaque and color page; e_gray - if opaque and gray page. NOTE that if page is set to be transparent (SetPageTransparent), the output color channels are already multiplied by the alpha channel.
• "BMP" : Bitmap image format (BMP).
• "JPEG" : Joint Photographic Experts Group (JPEG) image format.
• "PNG" : 24-bit W3C Portable Network Graphics (PNG) image format.
• "PNG8" : 8-bit, palettized PNG format. The exported file size should be smaller than the one generated using "PNG", possibly at the expense of some image quality.
• "TIFF" : Tag Image File Format (TIFF) image format.
• "TIFF8" : Tag Image File Format (TIFF) image format (with 8-bit palette).

encoderHints

Type: pdftron.SDFObj
encoderHints.
