| /* stbiw-0.92 - public domain - http://nothings.org/stb/stb_image_write.h | |||
| writes out PNG/BMP/TGA images to C stdio - Sean Barrett 2010 | |||
| no warranty implied; use at your own risk | |||
| Before #including, | |||
| #define STB_IMAGE_WRITE_IMPLEMENTATION | |||
| in the file that you want to have the implementation. | |||
| ABOUT: | |||
| This header file is a library for writing images to C stdio. It could be | |||
| adapted to write to memory or a general streaming interface; let me know. | |||
| The PNG output is not optimal; it is 20-50% larger than the file | |||
| written by a decent optimizing implementation. This library is designed | |||
| for source code compactness and simplicitly, not optimal image file size | |||
| or run-time performance. | |||
| USAGE: | |||
| There are three functions, one for each image file format: | |||
| int stbi_write_png(char const *filename, int w, int h, int comp, const void *data, int stride_in_bytes); | |||
| int stbi_write_bmp(char const *filename, int w, int h, int comp, const void *data); | |||
| int stbi_write_tga(char const *filename, int w, int h, int comp, const void *data); | |||
| Each function returns 0 on failure and non-0 on success. | |||
| The functions create an image file defined by the parameters. The image | |||
| is a rectangle of pixels stored from left-to-right, top-to-bottom. | |||
| Each pixel contains 'comp' channels of data stored interleaved with 8-bits | |||
| per channel, in the following order: 1=L, 2=LA, 3=RGB, 4=RGBA. (L is | |||
| luminance, i.e. monochrome "color", i.e. grey value.) The rectangle is | |||
| 'w' pixels wide and 'h' pixels tall. The *data pointer points to the | |||
| first byte of the top-left-most pixel. For PNG, "stride_in_bytes" is | |||
| the distance in bytes from the first byte of a row of pixels to the | |||
| first byte of the next row of pixels. Other file formats assume the | |||
| first byte of the each row of pixels begins immediately after the last | |||
| byte of the previous row. | |||
| PNG creates output files with the same number of components as the input. | |||
| The BMP and TGA formats expand Y to RGB in the file format. BMP does not | |||
| output alpha. | |||
| PNG supports writing rectangles of data even when the bytes storing rows of | |||
| data are not consecutive in memory (e.g. sub-rectangles of a larger image), | |||
| by supplying the stride between the beginning of adjacent rows. The other | |||
| formats do not. (Thus you cannot write an in-memory BMP through the BMP | |||
| writer, both because it is in BGR order and because it may have padding | |||
| at the end of the line.) | |||
