|
||||
writes out PNG/BMP/TGA/JPEG/HDR images to C stdio - Sean Barrett 2010-2015
|
||||
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.
|
||||
|
||||
Will probably not work correctly with strict-aliasing optimizations.
|
||||
|
||||
ABOUT:
|
||||
|
||||
This header file is a library for writing images to C stdio or a callback.
|
||||
|
||||
The PNG output is not optimal; it is 20-50% larger than the file
|
||||
written by a decent optimizing implementation; though providing a custom
|
||||
zlib compress function (see STBIW_ZLIB_COMPRESS) can mitigate that.
|
||||
This library is designed for source code compactness and simplicity,
|
||||
not optimal image file size or run-time performance.
|
||||
|
||||
BUILDING:
|
||||
|
||||
You can #define STBIW_ASSERT(x) before the #include to avoid using assert.h.
|
||||
You can #define STBIW_MALLOC(), STBIW_REALLOC(), and STBIW_FREE() to replace
|
||||
malloc,realloc,free.
|
||||
You can #define STBIW_MEMMOVE() to replace memmove()
|
||||
You can #define STBIW_ZLIB_COMPRESS to use a custom zlib-style compress function
|
||||
for PNG compression (instead of the builtin one), it must have the following signature:
|
||||
unsigned char * my_compress(unsigned char *data, int data_len, int *out_len, int quality);
|
||||
The returned data will be freed with STBIW_FREE() (free() by default),
|
||||
so it must be heap allocated with STBIW_MALLOC() (malloc() by default),
|
||||
|
||||
UNICODE:
|
||||
|
||||
If compiling for Windows and you wish to use Unicode filenames, compile
|
||||
with
|
||||
#define STBIW_WINDOWS_UTF8
|
||||
and pass utf8-encoded filenames. Call stbiw_convert_wchar_to_utf8 to convert
|
||||
Windows wchar_t filenames to utf8.
|
||||
|
||||
USAGE:
|
||||
|
||||
There are five 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);
|
||||
int stbi_write_jpg(char const *filename, int w, int h, int comp, const void *data, int quality);
|
||||
int stbi_write_hdr(char const *filename, int w, int h, int comp, const float *data);
|
||||
|
||||
void stbi_flip_vertically_on_write(int flag); // flag is non-zero to flip data vertically
|
||||
|
||||
There are also five equivalent functions that use an arbitrary write function. You are
|
||||
expected to open/close your file-equivalent before and after calling these:
|
||||
|
||||
int stbi_write_png_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data, int stride_in_bytes);
|
||||
int stbi_write_bmp_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
|
||||
int stbi_write_tga_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const void *data);
|
||||
int stbi_write_hdr_to_func(stbi_write_func *func, void *context, int w, int h, int comp, const float *data);
|
||||
int stbi_write_jpg_to_func(stbi_write_func *func, void *context, int x, int y, int comp, const void *data, int quality);
|
||||
|
||||
where the callback is:
|
||||
void stbi_write_func(void *context, void *data, int size);
|
||||
|
||||
You can configure it with these global variables:
|
||||
int stbi_write_tga_with_rle; // defaults to true; set to 0 to disable RLE
|
||||
int stbi_write_png_compression_level; // defaults to 8; set to higher for more compression
|
||||
int stbi_write_force_png_filter; // defaults to -1; set to 0..5 to force a filter mode
|
||||
|
||||
|
||||
You can define STBI_WRITE_NO_STDIO to disable the file variant of these
|
||||
functions, so the library will not use stdio.h at all. However, this will
|
||||
also disable HDR writing, because it requires stdio for formatted output.
|
||||
|
||||
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=Y, 2=YA, 3=RGB, 4=RGBA. (Y is
|
||||
monochrome color.) 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.
|
||||
|
||||
PNG creates output files with the same number of components as the input.
|
||||
The BMP format expands Y to RGB in the file format and 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 a native-format BMP through the BMP
|
||||
writer, both because it is in BGR order and because it may have padding
|
||||
at the end of the line.)
|
||||
|
||||
PNG allows you to set the deflate compression level by setting the global
|
||||
variable 'stbi_write_png_compression_level' (it defaults to 8).
|
||||
|
||||
HDR expects linear float data. Since the format is always 32-bit rgb(e)
|
||||
data, alpha (if provided) is discarded, and for monochrome data it is
|
||||
replicated across all three channels.
|
||||
|
||||
TGA supports RLE or non-RLE compressed data. To use non-RLE-compressed
|
||||
data, set the global variable 'stbi_write_tga_with_rle' to 0.
|
||||
|
||||
JPEG does ignore alpha channels in input data; quality is between 1 and 100.
|
||||
Higher quality looks better but results in a bigger image.
|
||||
JPEG baseline (no JPEG progressive).
