The RASTERPDFINFO structure provides information about a raster PDF file created created with the PDF support available in the LEADTOOLS PDF Pro, Pro Suite, and the Document and Medical toolkits.

Member Description
uStructSize Size of the structure. This must be set before passing this structure to the LEAD functions. Use the sizeof(RASTERPDFINFO) macro to calculate this value.
bIsLeadPdf Flag that indicates whether the PDF file was saved with the PDF support available in the LEADTOOLS PDF Pro, Pro Suite, and the Document and Medical toolkits.
  Value Meaning
  TRUE The file was created with the PDF support available in the LEADTOOLS PDF Pro, Pro Suite, and the Document and Medical toolkits. The other members of this structure are guaranteed to work. Also, L_DeletePage will work.
  FALSE The file was not created with the PDF support available in the LEADTOOLS PDF Pro, Pro Suite, and the Document and Medical toolkits.
nBitsPerPixel The bits/pixel of the raster image in PDF file. Horizontal display resolution in dots per inch. You can use it 0 to use the current screen horizontal resolution.
Format The format of the raster image in PDF file. Possible values are:
  Value Meaning
  FILE_RAS_PDF [146] Raster PDF uncompressed.
  FILE_RAS_PDF_G3_1D [147] Raster PDF with G3 1D Compression.
  FILE_RAS_PDF_G3_2D [148] Raster PDF with G3 2D Compression.
  FILE_RAS_PDF_G4 [149] Raster PDF with G4 Compression.
  FILE_RAS_PDF_JPEG [150] Raster PDF with JPEG 4:4:4 Compression.
  FILE_RAS_PDF_JPEG_422 [151] Raster PDF with JPEG 4:2:2 Compression.
  FILE_RAS_PDF_JPEG_411 [152] Raster PDF with JPEG 4:1:1 Compression.
  FILE_RAS_PDF_LZW [179] Raster PDF with LZW Compression.
  FILE_RAS_PDF_JBIG2 [188] Raster PDF with JBIG2 Compression.
  FILE_RAS_PDF_CMYK [333] Raster PDF with uncompressed CMYK data.
  FILE_RAS_PDF_LZW_CMYK [334] Raster PDF with LZW Compressed CMYK data.
nWidth Width of the image, in pixels.
nHeight Height of the image, in pixels.
XResolution Horizontal resolution of the first image.
YResolution Vertical resolution of the first image.
Version Value that indicates the PDF file version. For possible values, refer to RASTERPDFVERSION.
