Now using stb_image directly for loading image files, instead of SOIL (which is not maintained anymore)

|

Simple OpenGL Image Library
|
||||
|
||||
A tiny c library for uploading images as
|
||||
textures into OpenGL. Also saving and
|
||||
loading of images is supported.
|
||||
|
||||
I'm using Sean's Tool Box image loader as a base:
|
||||
http://www.nothings.org/
|
||||
|
||||
I'm upgrading it to load TGA and DDS files, and a direct
|
||||
path for loading DDS files straight into OpenGL textures,
|
||||
when applicable.
|
||||
|
||||
Image Formats:
|
||||
- BMP load & save
|
||||
- TGA load & save
|
||||
- DDS load & save
|
||||
- PNG load
|
||||
- JPG load
|
||||
|
||||
OpenGL Texture Features:
|
||||
- resample to power-of-two sizes
|
||||
- MIPmap generation
|
||||
- compressed texture S3TC formats (if supported)
|
||||
- can pre-multiply alpha for you, for better compositing
|
||||
- can flip image about the y-axis (except pre-compressed DDS files)
|
||||
|
||||
Thanks to:
|
||||
* Sean Barret - for the awesome stb_image
|
||||
* Dan Venkitachalam - for finding some non-compliant DDS files, and patching some explicit casts
|
||||
* everybody at gamedev.net

|
||||
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=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 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 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.)
