- Support writing metadata chunks with WebPAnimEncoder
- Add XMP metadata support to legacy WebPEncode wrapper
- Cleanup unused mux code in legacy WebPDecode wrapper
- Fix some bugs present when compiled without WebP Mux support
- Fix conversion from L/P/PA modes when saving WebP files
- Update existing tests, and add new ones for WebP animation and metadata support
Fixes EPS import by adding the missing "showpage" Postscript command
to the end of the gs call.

This is the Libav samples collection.
You can find samples of various common and uncommon
multimedia formats here. The size of the collection
currently is 54GB and growing.
You are free to download any samples you want, but
if you want to download more than just a few or want
to mirror the whole collection please send a mail to
webmaster(AT)libav(DOT)org *before* you start
and ask for permission.
We can also ship the samples collection to you for a
reasonable fee, inquire for details.
The best way to download samples is with rsync. If you decide
to fetch a large amount (more than 1GB), please limit the rate
to no more than 50 kBps (use the --bwlimit option of rsync).
Please be aware that this samples collection contains a lot
of files that are very obscure, broken in various ways or
are just simply out of use. Hence, it doesn't make sense
to download all of them, unless you are developing a player
applic
We were encountering some errors when saving specific JPEG images.
The error was shown in stderr as:
IOError: encoder error -2 when writing image file
And on stdout it printed:
Suspension not allowed here
The problem was the bufsize not contemplating the icc_profile block.
* DPI is a tuple
* Some EXIF only contains an X resolution for DPI
* Refactor
* Test with no DPI in EXIF
* Handle EXIF with no DPI
* Created with: exiftool "-*resolution*"= photoshop-200dpi.jpg
* Test when not in EXIF, DPI==72,72
* Use X resolution for Y, default to 72,72 dpi
* Created with: exiftool -exif:ResolutionUnit=cm photoshop-200dpi.jpg
* Test for EXIF with dpcm instead of dpi
* Convert dpcm to dpi, and default to inches if unit unknown
* EMF: support negative bounding box coordinates
Similar to placeable WMF, bounding box coordinates
should be interpreted as signed integer, otherwise
opening EMF file with negative (x0,y0) fails.
* Basic load tests for WMF and EMF formats
* WMF/WMF tests: just test open(), not load()
Not sure why load() fails on Debian build. Well, at least we can test
open().
* WMF/EMF: Unpack signed integers using unpack()
* WMF/EMF: Compare to reference PNG rendering
* EMF/WMF comparison: use assert_image_similar()
* Use similarity epsilon 0.5 for WMF, as vector rendering looks different across Windows platforms
* Trigger rebuild
The DIB image format uses the 40 byte BMP header, followed by 3 masks
for RGB channels. We were reading 4 masks, consuming the first pixel
of the image.
Mostly fixes issue #1293. Remaining issue: alpha channel is actually a
transparency mask.
