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.
