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.

rgb - RGB
cmyk - CMYK
lab - L*a*b
icc - ICC Based
index - Indexed Color
sep - Separation
