2018-11-07Fix typo.Tor Andersson
2018-11-07Fix 698971: Detect ICC colorspace mismatch in TIFF loader.Tor Andersson
Make sure that the ICC colorspace has the same number of components as the photometric interpretation.
2018-10-25Guard loading embedded ICC profiles in images with FZ_ENABLE_ICC.Tor Andersson
Stops all the extra errors and warnings about missing ICC support.
2018-09-05Use colorspace type enum instead of magic profile names.Tor Andersson
2018-04-03Don't implicitly drop in fz_open_* chained filters.Tor Andersson
2018-02-01Drop JPEG/J2K/JPEG-XR/PNG/TIFF colorspaces even upon exception.Sebastian Rasmussen
For TIFF it was not just the colorspace, but other data as well.
2017-10-25Fix colorspace reference counting in fz_load_*_info.Tor Andersson
These are called from fz_new_image_from_buffer.
2017-10-25Use ICC profile in tiff file if presentMichael Vrhel
2017-10-25Add CIE Lab color space support to tiff loaderMichael Vrhel
2017-10-12Make image loading use const data pointers.Tor Andersson
2017-09-20tiff: Support images with 24/32 bits per component.Sebastian Rasmussen
2017-09-07Initialize variables to appease clang scan-build.Sebastian Rasmussen
2017-07-19Add spots to fz_pixmaps.Robin Watts
Update separations interface further to cope with whether spots should be rendered separately, or as composite colors.
2017-07-17Don't convert cmyka images to rgbaMichael Vrhel
We should handle the cmyka images in their native form now that we are holding the data inverted. Fixes fts_17_1700.pdf Also fixes fts_43xx.xps
2017-06-27tiff: Decoders drop encoded stream on their own.Sebastian Rasmussen
As a part of this, if the compression method is unknown drop the encoded stream before rethrowing the exception.
2017-06-11Ensure TIFF images have the correct colorspace.Robin Watts
CMYK+Alpha get resolved to RGB+Alpha as part of loading.
2017-06-02tiff: Avoid dropping wild pointer in case of error.Sebastian Rasmussen
2017-06-01tiff: Check for degenerate YCbCr subsampling factors.Sebastian Rasmussen
2017-05-31Avoid double literals causing casts to float.Sebastian Rasmussen
2017-05-08tiff: Fix bug where both tiff and fax decoders inverted the image.Sebastian Rasmussen
2017-05-02tiff: Fix typo in validation of tiles images.Sebastian Rasmussen
2017-05-02tiff: Scale Lab components to suit colorspace.Sebastian Rasmussen
TIFF already provides the a/b components prescaled. Previously the colorspace color conversion process scaled them again, causing out of range behaviour.
2017-04-30tiff: Set k>0 for CCITT fax group 3 1D/2D compression.Sebastian Rasmussen
Previously, if a TIFF file was encoded using CCITT fax group 3 compression and mixing 1D and 2D codes, the fax decoder was not instructed to parse the 1D/2D indication bit after EOL. This caused later issues when parsing the succeeding 1D/2D code, e.g. resulting in the decoder encountering a negative 1D code and returning with an error. Setting k>0 means the 1D/2D indication bit is parsed. The CCITT fax group 3 specification recommends setting k based on the vertical resolution. MuPDF's fax decoder depends only on if k is <0, 0 or >0, not its value (as recommended by the PDF specification). Therefore it is not necessary to use the vertical resolution to determine a particular value for k.
2017-04-27Include required system headers.Tor Andersson
2016-12-27Common code to ensure we only premultiply pixmaps with additive colors.Tor Andersson
2016-12-14Let pixmap colorspace conversion create new pixmap.Sebastian Rasmussen
This moves dropping the converted pixmap into fz_convert_pixmap(), which relieves every caller from doing so. Moreover resolution, position and interpolation are kept.
2016-12-14Plug pixmap leak when fz_convert_pixmap() throws.Sebastian Rasmussen
2016-11-03Fix signed/unsigned and size_t/int/fz_off_t warnings.Robin Watts
All seen in MSVC, mostly in 64bit builds.
2016-11-02Don't check for NULL before calls to fz_free.Sebastian Rasmussen
2016-11-01tiff: Plug leak where superflous pixmaps was created.Sebastian Rasmussen
2016-10-26tiff: Drop pixmap when exception is thrown.Sebastian Rasmussen
Also don't check for NULL unnecessarily.
2016-10-26tiff: Always set colorspace when reading image info.Sebastian Rasmussen
Commit 3059b6908208fbb9547e6876332a5b42a6406d1a accidentally caused colorspace to not be set when reading image information.
2016-10-18tiff: Support stripped YCbCr images.Sebastian Rasmussen
2016-10-18tiff: Cosmetic cleanup of code.Sebastian Rasmussen
In preparation for YCbCr support, rename some functions and make variable names more generic. Also remove fz_ prefix from static functions.
2016-10-16tiff: Plug pixmap leak should conversion fail.Sebastian Rasmussen
2016-09-28tiff: Do not clobber input buffer if fill order is reversed.Sebastian Rasmussen
2016-09-28tiff: Do error handling for decoders in a single place.Sebastian Rasmussen
2016-09-28tiff: Validate that tag/tile/strip offsets are within bounds.Sebastian Rasmussen
2016-09-28Bug 697166: tiff: Avoid freeing offset/bytecount arrays twice.Sebastian Rasmussen
2016-09-28Bug 697165: tiff: Do not allow duplicate array tags.Sebastian Rasmussen
Previously this caused a memory leak.
2016-09-28Bug 697155: tiff: Drop stream if compression is unknown.Sebastian Rasmussen
