- Next version:
|
|
* New function: WebPMuxGetCanvasSize
|
|
* BMP and TIFF format output added to 'dwebp'
|
|
* Significant memory reduction for decoding lossy images with alpha.
|
|
* Intertwined decoding of RGB and alpha for a shorter
|
|
time-to-first-decoded-pixel.
|
|
* WebPIterator has a new member 'has_alpha' denoting whether the frame
|
|
contains transparency.
|
|
|
|
- 6/13/13: version 0.3.1
|
|
This is a binary compatible release.
|
|
* Add incremental decoding support for images containing ALPH and ICCP chunks.
|
|
* Python bindings via swig for the simple encode/decode interfaces similar to
|
|
Java.
|
|
|
|
- 3/20/13: version 0.3.0
|
|
This is a binary compatible release.
|
|
* WebPINewRGB/WebPINewYUVA accept being passed a NULL output buffer
|
|
and will perform auto-allocation.
|
|
* default filter option is now '-strong -f 60'
|
|
* encoding speed-up for lossy methods 3 to 6
|
|
* alpha encoding can be done in parallel to lossy using 'cwebp -mt ...'
|
|
* color profile, metadata (XMP/EXIF) and animation support finalized in the
|
|
container.
|
|
* various NEON assembly additions
|
|
Tool updates / additions:
|
|
* gif2webp added
|
|
* vwebp given color profile & animation support
|
|
* cwebp can preserve color profile / metadata with '-metadata'
|
|
|
|
- 10/30/12: version 0.2.1
|
|
* Various security related fixes
|
|
* cwebp.exe: fix import errors on Windows XP
|
|
* enable DLL builds for mingw targets
|
|
|
|
- 8/3/12: version 0.2.0
|
|
* Add support for ARGB -> YUVA conversion for lossless decoder
|
|
New functions: WebPINewYUVA, WebPIDecGetYUVA
|
|
* Add stats for lossless and alpha encoding
|
|
* Security related hardening: allocation and size checks
|
|
* Add PAM output support to dwebp
|
|
|
|
- 7/19/12: version 0.1.99
|
|
* This is a pre-release of 0.2.0, not an rc to allow for further
|
|
incompatible changes based on user feedback.
|
|
* Alpha channel encode/decode support.
|
|
* Lossless encoder/decoder.
|
|
* Add TIFF input support to cwebp.
|
|
Incompatible changes:
|
|
* The encode ABI has been modified to support alpha encoding.
|
|
* Deprecated function WebPINew() has been removed.
|
|
* Decode function signatures have changed to consistently use size_t over
|
|
int/uint32_t.
|
|
* decode_vp8.h is no longer installed system-wide.
|
|
* cwebp will encode the alpha channel if present.
|
|
|
|
- 9/19/11: version 0.1.3
|
|
* Advanced decoding APIs.
|
|
* On-the-fly cropping and rescaling of images.
|
|
* SSE2 instructions for decoding performance optimizations on x86 based platforms.
|
|
* Support Multi-threaded decoding.
|
|
* 40% improvement in Decoding performance.
|
|
* Add support for RGB565, RGBA4444 & ARGB image colorspace.
|
|
* Better handling of large picture encoding.
|
|
|
|
- 3/25/11: version 0.1.2
|
|
* Incremental decoding: picture can be decoded byte-by-byte if needs be.
|
|
* lot of bug-fixes, consolidation and stabilization
|
|
|
|
- 2/23/11: initial release of version 0.1, with the new encoder
|
|
- 9/30/10: initial release version with only the lightweight decoder
