|
|
|
|
|
<li> Fix a couple of issues that trigger failures in some
|
|
|
|
|
cases when using TIFFReadScanline() with JPEG compressed
|
|
|
|
|
subsampled ycbcr images.
|
|
|
|
|
http://bugzilla.maptools.org/show_bug.cgi?id=1936
|
|
|
|
|
|
|
|
|
|
<li> Ensure tile and scanline sizes are reset when moving to
|
|
|
|
|
new directories.
|
|
|
|
|
http://bugzilla.maptools.org/show_bug.cgi?id=1936
|
|
|
|
|
|
|
|
|
|
<li> Do not generate a JPEGTables tag when creating the JPEG
|
|
|
|
|
TIFF as is is not required in order to prevent it from being
|
|
|
|
|
unused and filled with invalid data. (Leave it to be
|
|
|
|
|
generated by later activity.)
|
|
|
|
|
http://bugzilla.maptools.org/show_bug.cgi?id=2135
|
|
|
|
|
|
|
|
|
|
<li> Don't return error on badly-terminated MMR strips.
|
|
|
|
|
http://bugzilla.maptools.org/show_bug.cgi?id=2029
|
|
|
|
|
|
|
|
|
|
<li> Have TIFFTAG_REFERENCEBLACKWHITE always print 6 floats
|
|
|
|
|
instead of 2*SamplesPerPixel.
|
|
|
|
|
http://bugzilla.maptools.org/show_bug.cgi?id=2186
|
|
|
|
|
|
|
|
|
|
<li> Ensure that JPEG quality is always set in
|
|
|
|
|
JPEGPreEncode(), not just when we want to output local tables.
|
|
|
|
|
Otherwise the quality used during compression may not be right
|
|
|
|
|
and might not match the tables in the tables tag. This bug
|
|
|
|
|
only occurs when seeking between directories in the midst of
|
|
|
|
|
writing blocks. http://trac.osgeo.org/gdal/ticket/3539
|
|
|
|
|
|
|
|
|
|
<li> OJPEG: Report an error and avoid a crash if the input
|
|
|
|
|
file is so broken that the strip offsets are not defined.
|
|
|
|
|
|
|
|
|
|
<li> Eliminate FAX3 decoder buffer overrun possibility
|
|
|
|
|
(CVE-2010-1411).
|
|
|
|
|
|
|
|
|
|
<li> Restore ReferenceBlackWhite as a non-custom field. This
|
|
|
|
|
avoids a multi-thread reentrancy problem as well as fixing
|
|
|
|
|
output of wrong tag value due to redundant definitions for the
|
|
|
|
|
same tag in the tiffFieldInfo[] array. Resolves

|
<li> tiff2pdf: Write the JPEG SOI headers into the TIFF strip
|
|
|
|
|
data rather than skipping them. This fixes the ability to view in
|
|
|
|
|
Acrobat Reader, Evince, and Ghostscript.

|
|
|
|
|
|
|
|
|
|
<li> ppm2tiff: While case for parsing comment line
|
|
|
|
|
requires extra parenthesis to work as expected. Reported by
|
|
|
|
|
Thomas Sinclair.
|
|
|
|
|
|
|
|
|
|
<li> tiffcp: add a new option -x to force merged tiff
|
|
|
|
|
file PAGENUMBER value in sequence for users who care the page
|
|
|
|
|
sequence, this will also prevent tiff2pdf from creating pdf file from
|
|
|
|
|
the merged tiff file with wrong page sequence.
|
|
|
|
|
|
|
|
|
|
<li> tiffcp: Applied Tom Lane's patch to reject YCbCr
|
|
|
|
|
subsampled data since tiffcp currently doesn't support it.
