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