No external dependencies. Written in C99. 4 | 5 | | Library | Description 6 | |--------------------|--------------------------------------------------------------------------------------------------- 7 | | [ok_png](ok_png.h) | Reads PNG files. Supports Apple's proprietary `CgBI` chunk. Tested against the PngSuite. 8 | | [ok_jpg](ok_jpg.h) | Reads JPEG files. Baseline and progressive formats. Interprets EXIF orientation tags. No CMYK support. 9 | | [ok_wav](ok_wav.h) | Reads WAV and CAF files. PCM, u-law, a-law, and ADPCM formats. 10 | | [ok_fnt](ok_fnt.h) | Reads AngelCode BMFont files. Binary format from AngelCode Bitmap Font Generator v1.10 or newer. 11 | | [ok_csv](ok_csv.h) | Reads Comma-Separated Values files. 12 | | [ok_mo](ok_mo.h) | Reads gettext MO files. 13 | 14 | The source files do not depend on one another. If all you need is to read a PNG file, just 15 | use `ok_png.h` and `ok_png.c`. 16 | 17 | The `CMakeLists.txt` file can be used but is not required. 18 | 19 | The `ok_png`, `ok_jpg`, and `ok_wav` functions include: 20 | * Option to use a custom allocator (`ok_png_read_with_allocator`, etc.) 21 | * Fuzz tests. 22 | 23 | The `ok_png` and `ok_jpg` functions include these decode options: 24 | * Get the image dimensions without decoding image data. 25 | * Premultiply alpha. 26 | * Flip the image vertically. 27 | 28 | ## Example: Decode PNG 29 | 30 | ```C 31 | #include 32 | #include "ok_png.h" 33 | 34 | int main() { 35 | FILE *file = fopen("my_image.png", "rb"); 36 | ok_png image = ok_png_read(file, OK_PNG_COLOR_FORMAT_RGBA | OK_PNG_PREMULTIPLIED_ALPHA | OK_PNG_FLIP_Y); 37 | fclose(file); 38 | if (image.data) { 39 | printf("Got image! Size: %li x %li\n", (long)image.width, (long)image.height); 40 | free(image.data); 41 | } 42 | return 0; 43 | } 44 | ``` 45 | 46 | ## Recent breaking changes in `ok_png`, `ok_jpg`, and `ok_wav`: 47 | * The read functions now return the `ok_png`, `ok_jpg`, and `ok_wav` structs on the stack instead of the heap. (These structs are small, around 24-32 bytes). 48 | * Replaced `ok_png_read_to_buffer` with `ok_png_read_with_allocator`. 49 | * Replaced `ok_png_read_from_callbacks` with `ok_png_read_from_input`. 50 | * Replaced `error_message` with `error_code`. 51 | * Removed `ok_png_free`. Free `png.data` directly instead. 52 | 53 | -------------------------------------------------------------------------------- /ok_csv.h: -------------------------------------------------------------------------------- 1 | // ok-file-formats 2 | // https://github.com/brackeen/ok-file-formats 3 | 4 | #ifndef OK_CSV_H 5 | #define OK_CSV_H 6 | 7 | /** 8 | * @file 9 | * Functions to read CSV (Comma-Separated Values) files. 10 | * - Reads CSV files as defined by RFC 4180. 11 | * - Properly handles escaped fields. 12 | * 13 | * Example: 14 | * 15 | * #include 16 | * #include "ok_csv.h" 17 | * int main() { 18 | * FILE *file = fopen("my_data.csv", "rb"); 19 | * ok_csv *csv = ok_csv_read(file); 20 | * fclose(file); 21 | * if (csv->num_records > 0) { 22 | * printf("Got CSV! %i records\n", csv->num_records); 23 | * if (csv->num_fields[0] > 2) { 24 | * printf("Third field in first record: '%s'\n", csv->fields[0][2]); 25 | * } 26 | * } 27 | * ok_csv_free(csv); 28 | * return 0; 29 | * } 30 | */ 31 | 32 | #include 33 | #include 34 | #ifndef OK_NO_STDIO 35 | #include 36 | #endif 37 | 38 | #ifdef __cplusplus 39 | extern "C" { 40 | #endif 41 | 42 | /** 43 | * The data returned from #ok_csv_read(). 44 | */ 45 | typedef struct { 46 | /// Number of records (rows) 47 | size_t num_records; 48 | /// Number of fields (columns) for each record. 49 | size_t *num_fields; 50 | /// Fields.

-------------------------------------------------------------------------------- /test/README.md: -------------------------------------------------------------------------------- 1 | # ok-file-formats tests 2 | 3 | There are two tests here: A correctness test and a fuzz test. 4 | 5 | The correctness test checks the output of `ok_png`, `ok_jpg`, and `ok_wav` against the output of 6 | [ImageMagick 7](https://www.imagemagick.org/), [SoX 14](http://sox.sourceforge.net/)) and, on macOS, 7 | the pre-installed `afconvert`. 8 | 9 | The fuzz test uses American Fuzzy Lop++. 10 | 11 | ## Requirements 12 | 13 | On macOS, install ImageMagick 7 and SoX: 14 | 15 | brew install imagemagick sox 16 | 17 | For the fuzz test, install American Fuzzy Lop++: 18 | 19 | brew install afl++ 20 | 21 | ## Correctness test 22 | 23 | To run the correctness test: 24 | 25 | cmake -B build && cmake --build build && ctest --verbose --test-dir build 26 | 27 | Alternatively, to run the correctness test from an IDE: 28 | 29 | cmake -B build && cmake --build build -G Xcode 30 | 31 | ### PNG 32 | 33 | For PNG tests, the [PngSuite](http://www.schaik.com/pngsuite/pngsuite.html) images from Willem van 34 | Schaik are used. 35 | 36 | Tested against ImageMagick 7.0.8-23. Earlier versions of ImageMagick 7 may have incorrect output for 37 | some PNG files. 38 | 39 | To test Apple's proprietary PNG extensions, the tests must run on an actual iOS device, and not the 40 | simulator. 41 | 42 | ### JPEG 43 | 44 | The JPEG tests disable "fancy upsampling" because results will vary based on what version of the 45 | libjpeg library ImageMagick uses. The `ok_jpg` decoder uses a similar upsampling method than the 46 | libjpeg-8d library, but is different that libjpeg-turbo. 47 | 48 | Although there are only a few dozen JPEGs in the included tests, `ok_jpg` has been tested against 49 | thousands of images, some dated back to the 90's. 50 | 51 | ## Fuzz test 52 | 53 | To build `ok-file-formats-fuzz-test`: 54 | 55 | cmake -B build -DFUZZ_TEST=ON && cmake --build build 56 | 57 | Optionally, enable Address Sanitizer (warning, this is slow): 58 | 59 | cmake -B build -DFUZZ_TEST=ON -DFUZZ_WITH_ASAN=ON && cmake --build build 60 | 61 | Then run one of these commands: 62 | 63 | afl-fuzz -i build/gen/fuzzing/input/wav -o build/gen/fuzzing/afl_results/wav ./build/ok-file-formats-fuzz-test --wav 64 | afl-fuzz -i build/gen/fuzzing/input/caf -o build/gen/fuzzing/afl_results/caf ./build/ok-file-formats-fuzz-test --caf 65 | afl-fuzz -t 1000 -x png.dict -i build/gen/fuzzing/input/png -o build/gen/fuzzing/afl_results/png ./build/ok-file-formats-fuzz-test --png 66 | afl-fuzz -t 1000 -x jpg.dict -i build/gen/fuzzing/input/jpg -o build/gen/fuzzing/afl_results/jpg ./build/ok-file-formats-fuzz-test --jpg 67 | 68 | Fuzzing will take hours or even days to complete, depending on the input. `afl-fuzz` runs on one 69 | core, so if you have a multi-core machine you can run multiple tests at once. 70 | 71 | The generated input cases are imperfect. For more input cases, see 72 | [Mozilla's Fuzzdata samples](https://github.com/MozillaSecurity/fuzzdata/tree/master/samples) and 73 | [input cases provided by moonAgirl](https://github.com/moonAgirl/Bugs/tree/master/ok-file-formats). 74 | -------------------------------------------------------------------------------- /test/cmake/ConvertPNG.cmake: -------------------------------------------------------------------------------- 1 | # Converts the png file ${IN_FILE} to the RGBA8888 file ${OUT_FILE} 2 | # The gAMA chunk is ignored. 3 | # The "-intensity Average" setting prevents ImageMagick from color-converting grayscale files. 4 | # For invalid files, a zero-byte output file is created. 5 | execute_process( 6 | COMMAND ${IMAGEMAGICK_COMMAND} -define png:bit-depth=8 -define png:exclude-chunk=gAMA ${IN_FILE} ${CMAKE_CURRENT_LIST_DIR}/temp.png 7 | ERROR_QUIET 8 | ) 9 | if (EXISTS ${CMAKE_CURRENT_LIST_DIR}/temp.png) 10 | execute_process(COMMAND ${IMAGEMAGICK_COMMAND} -intensity Average ${CMAKE_CURRENT_LIST_DIR}/temp.png ${OUT_FILE}) 11 | file(REMOVE ${CMAKE_CURRENT_LIST_DIR}/temp.png) 12 | else() 13 | file(WRITE ${OUT_FILE} "") 14 | endif() 15 | -------------------------------------------------------------------------------- /test/cmake/FileInformation.cmake: -------------------------------------------------------------------------------- 1 | # - CMake module for getting file information such as size and modification date 2 | # 3 | # This module overrides the built-in CMake command file to provide two additional sub-commands 4 | # SIZE and TIMESTAMP on all platforms.
