An additional intellectual 21property rights grant can be found in the file PATENTS. 22 23 24API: 25==== 26 27This is mainly just one function to call, so just have a look at 28the file src/webp/decode.h for the details and variants: 29 30#include "webp/decode.h" 31uint8_t* WebPDecodeRGB(const uint8_t* data, uint32_t data_size, 32 int *width, int *height); 33 34A lower-level API is available from the header file <webp/decode_vp8.h> 35 36 37Building: 38========= 39 40If everything goes right, then: 41 42./configure 43make 44make install 45 46should be all you need to have the following files 47 48/usr/local/include/webp/decode.h 49/usr/local/include/webp/decode_vp8.h 50/usr/local/lib/libwebpdecode.* 51 52installed. 53 54 55Decoding example: 56================= 57 58there's a decoding example in example/dwebp.c which will take a .webp file and 59decode it to a PPM image file. This is simply to demonstrate use of the API. 60You can verify the file test.webp decodes to exactly the same as test_ref.ppm: 61 `cd examples && ./dwebp test.webp -o test.ppm && diff test.ppm test_ref.ppm` 62 63Bugs: 64===== 65 66Please report all bugs to our issue tracker: 67 http://code.google.com/p/webp/issues 68Patches welcome!
