NAME
pdfimages - Portable Document Format (PDF) image extractor (version 3.03) SYNOPSIS
pdfimages [options] PDF-file image-root DESCRIPTION
Pdfimages saves images from a Portable Document Format (PDF) file as Portable Pixmap (PPM), Portable Bitmap (PBM), or JPEG files. Pdfimages reads the PDF file PDF-file, scans one or more pages, and writes one PPM, PBM, or JPEG file for each image, image-root-nnn.xxx, where nnn is the image number and xxx is the image type (.ppm, .pbm, .jpg). OPTIONS
-f number Specifies the first page to scan. -l number Specifies the last page to scan. -j Normally, all images are written as PBM (for monochrome images) or PPM (for non-monochrome images) files. With this option, images in DCT format are saved as JPEG files. All non-DCT images are saved in PBM/PPM format as usual. -list Instead of writing the images, list the images along with various information for each image. Do not specify an image-root with this option. The following information is listed for each font: page the page number containing the image num the image number type the image type: image - an opaque image mask - a monochrome mask image smask - a soft-mask image stencil - a monochrome mask image used for painting a color or pattern Note: Tranparency in images is represented in PDF using a separate image for the image and the mask/smask. The mask/smask used as part of a transparent image always immediately follows the image in the image list. width image width (in pixels) height image height (in pixels) Note: the image width/height is the size of the embedded image, not the size the image will be rendered at. color image color space: gray - Gray rgb - RGB cmyk - CMYK lab - L*a*b icc - ICC Based index - Indexed Color sep - Separation devn - DeviceN comp number of color components bpc bits per component enc encoding: image - raster image (may be Flate or LZW compressed but does not use an image encoding) jpeg - Joint Photographic Experts Group jp2 - JPEG2000 jbig2 - Joint Bi-Level Image Experts Group ccitt - CCITT Group 3 or Group 4 Fax interp "yes" if the interpolation is to be performed when scaling up the image object ID the font dictionary object ID (number and generation) -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -p Include page numbers in output file names. -q Don't print any messages or errors. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) EXIT CODES
The Xpdf tools use the following exit codes: 0 No error. 1 Error opening a PDF file. 2 Error opening an output file. 3 Error related to PDF permissions. 99 Other error. AUTHOR

NAME
pdftoppm - Portable Document Format (PDF) to Portable Pixmap (PPM) converter (version 3.00) SYNOPSIS
pdftoppm [options] PDF-file PPM-root DESCRIPTION
Pdftoppm converts Portable Document Format (PDF) files to color image files in Portable Pixmap (PPM) format, grayscale image files in Por- table Graymap (PGM) format, or monochrome image files in Portable Bitmap (PBM) format. Pdftoppm reads the PDF file, PDF-file, and writes one PPM file for each page, PPM-root-number.ppm, where number is the page number. OPTIONS
-f number Specifies the first page to convert. -l number Specifies the last page to convert. -o Generates only the odd numbered pages. -e Generates only the even numbered pages. -singlefile Writes only the first page and does not add digits. -r number Specifies the X and Y resolution, in DPI. The default is 150 DPI. -rx number Specifies the X resolution, in DPI. The default is 150 DPI. -ry number Specifies the Y resolution, in DPI. The default is 150 DPI. -scale-to number Scales each page to fit in scale-to*scale-to pixel box. -scale-to-x number Scales each page horizontally to fit in scale-to-x pixels. -scale-to-y number Scales each page vertically to fit in scale-to-y pixels. -x number Specifies the x-coordinate of the crop area top left corner -y number Specifies the y-coordinate of the crop area top left corner -W number Specifies the width of crop area in pixels (default is 0) -H number Specifies the height of crop area in pixels (default is 0) -sz number Specifies the size of crop square in pixels (sets W and H) -cropbox Uses the crop box rather than media box when generating the files -mono Generate a monochrome PBM file (instead of a color PPM file). -gray Generate a grayscale PGM file (instead of a color PPM file). -png Generates a PNG file instead a PPM file. -jpeg Generates a JPEG file instead a PPM file. -tiff Generates a TIFF file instead a PPM file. -tiffcompression none | packbits | jpeg | lzw | deflate Specifies the TIFF compression type. This defaults to "none". -freetype yes | no Enable or disable FreeType (a TrueType / Type 1 font rasterizer). This defaults to "yes". -aa yes | no Enable or disable font anti-aliasing. This defaults to "yes". -aaVector yes | no Enable or disable vector anti-aliasing. This defaults to "yes". -opw password Specify the owner password for the PDF file. Providing this will bypass all security restrictions. -upw password Specify the user password for the PDF file. -q Don't print any messages or errors. -v Print copyright and version information. -h Print usage information. (-help and --help are equivalent.) EXIT CODES
