Upgrade to release 10.10.0:
- {meth}pikepdf.PdfImage.as_pil_image and
{meth}pikepdf.PdfImage.extract_to now apply an image's soft mask
(/SMask) or explicit/colour-key mask
- (/Mask) by default, returning an image with an alpha channel (LA
or RGBA) and writing a transparency-capable format (.png).
Previously the mask was silently ignored and the opaque base
image was returned. Images without a mask are unaffected. Pass
apply_mask=False to recover the old behavior and obtain only the
opaque base image.
- Image masking is now honored when extracting images. /SMask soft
masks, /Mask stencil (explicit) masks, and /Mask colour-key masks
are composited into an alpha channel. Soft-mask images whose
resolution differs from the base image are resampled to match
(ISO 32000-2 ยง8.9.6).
- Added support for /CalRGB, /CalGray and /CalCMYK images, which
previously raised NotImplementedError. The samples are decoded as
their device equivalents, and for CalRGB/CalGray an ICC profile
synthesized from the colour space's WhitePoint/Gamma/Matrix is
attached to the extracted image so the calibration is preserved
for colour-managed consumers.
- Added support for the /Lab colour space, extracted as a Pillow
LAB image (saved as TIFF) with the PDF L*/a*/b* ranges remapped
to Pillow's conventions.
- Added support for 16-bit-per-component images. 16-bit grayscale
is extracted losslessly as Pillow I;16; 16-bit RGB and CMYK are
reduced to 8-bit (with a warning) because Pillow has no
higher-bit-depth raw mode for them.
- Extended colour-space handling to several cases that previously
raised NotImplementedError: ICCBased CMYK images and indexed
images now produce the correct default /Decode array, and inline
images that name their colour space now resolve it from the
in-scope /Resources when obtained via
{func}pikepdf.parse_content_stream.
- JPEG (/DCTDecode) images with a non-default /ColorTransform -- a
YCCK CMYK or a non-YCbCr RGB JPEG -- are now decoded via Pillow
(which honours the JPEG's own markers) and transcoded, instead of
failing to extract.
- Filter chains that wrap a single terminal image codec (/DCTDecode,
/CCITTFaxDecode, /JPXDecode, /JBIG2Decode) in any number of
generalized/specialized filters (Flate, LZW, ASCII85/Hex,
RunLength) are now peeled and extracted seamlessly.
- Added {attr}pikepdf.PdfImage.MAX_IMAGE_PIXELS, a settable
class-level limit on the number of pixels pikepdf will decode
from a single image. Until set, it defaults to max(500_000_000,
PIL.Image.MAX_IMAGE_PIXELS) -- a floor suited to high-DPI scanned
PDFs -- and tracks Pillow's setting; once assigned it becomes
independent of Pillow. Set it to None to disable the check.
- {class}pikepdf.Array now implements the standard Python list
interface: slicing (including del on slices and slice assignment),
and the clear(), count(), index(), insert(), pop(), remove(),
and reverse() methods.
