To add a new filter, - write a filter function and add it to stbir__filter_info_table. - - PROGRESS - For interactive use with slow resize operations, you can install - a progress-report callback: - - #define STBIR_PROGRESS_REPORT(val) some_func(val) - - The parameter val is a float which goes from 0 to 1 as progress is made. - - For example: - - static void my_progress_report(float progress); - #define STBIR_PROGRESS_REPORT(val) my_progress_report(val) - - #define STB_IMAGE_RESIZE_IMPLEMENTATION - #include "stb_image_resize.h" - - static void my_progress_report(float progress) - { - printf("Progress: %f%%\n", progress*100); - } - - MAX CHANNELS - If your image has more than 64 channels, define STBIR_MAX_CHANNELS - to the max you'll have. - - ALPHA CHANNEL - Most of the resizing functions provide the ability to control how - the alpha channel of an image is processed. The important things - to know about this: - - 1. The best mathematically-behaved version of alpha to use is - called "premultiplied alpha", in which the other color channels - have had the alpha value multiplied in. If you use premultiplied - alpha, linear filtering (such as image resampling done by this - library, or performed in texture units on GPUs) does the "right - thing". While premultiplied alpha is standard in the movie CGI - industry, it is still uncommon in the videogame/real-time world. - - If you linearly filter non-premultiplied alpha, strange effects - occur. (For example, the 50/50 average of 99% transparent bright green - and 1% transparent black produces 50% transparent dark green when - non-premultiplied, whereas premultiplied it produces 50% - transparent near-black. The former introduces green energy - that doesn't exist in the source image.) - - 2. Artists should not edit premultiplied-alpha images; artists - want non-premultiplied alpha images. Thus, art tools generally output - non-premultiplied alpha images. - - 3. You will get best results in most cases by converting images - to premultiplied alpha before processing them mathematically. - - 4. If you pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, the - resizer does not do anything special for the alpha channel; - it is resampled identically to other channels. This produces - the correct results for premultiplied-alpha images, but produces - less-than-ideal results for non-premultiplied-alpha images. - - 5. If you do not pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, - then the resizer weights the contribution of input pixels - based on their alpha values, or, equivalently, it multiplies - the alpha value into the color channels, resamples, then divides - by the resultant alpha value. Input pixels which have alpha=0 do - not contribute at all to output pixels unless _all_ of the input - pixels affecting that output pixel have alpha=0, in which case - the result for that pixel is the same as it would be without - STBIR_FLAG_ALPHA_PREMULTIPLIED. However, this is only true for - input images in integer formats. For input images in float format, - input pixels with alpha=0 have no effect, and output pixels - which have alpha=0 will be 0 in all channels. (For float images, - you can manually achieve the same result by adding a tiny epsilon - value to the alpha channel of every image, and then subtracting - or clamping it at the end.) - - 6. You can suppress the behavior described in #5 and make - all-0-alpha pixels have 0 in all channels by #defining - STBIR_NO_ALPHA_EPSILON. - - 7. You can separately control whether the alpha channel is - interpreted as linear or affected by the colorspace. By default - it is linear; you almost never want to apply the colorspace. - (For example, graphics hardware does not apply sRGB conversion - to the alpha channel.) - - CONTRIBUTORS - Jorge L Rodriguez: Implementation - Sean Barrett: API design, optimizations - Aras Pranckevicius: bugfix - Nathan Reed: warning fixes - - REVISIONS - 0.97 (2020-02-02) fixed warning - 0.96 (2019-03-04) fixed warnings - 0.95 (2017-07-23) fixed warnings - 0.94 (2017-03-18) fixed warnings - 0.93 (2017-03-03) fixed bug with certain combinations of heights - 0.92 (2017-01-02) fix integer overflow on large (>2GB) images - 0.91 (2016-04-02) fix warnings; fix handling of subpixel regions - 0.90 (2014-09-17) first released version - - LICENSE - See end of file for license information. - - TODO - Don't decode all of the image data when only processing a partial tile - Don't use full-width decode buffers when only processing a partial tile - When processing wide images, break processing into tiles so data fits in L1 cache - Installable filters? - Resize that respects alpha test coverage - (Reference code: FloatImage::alphaTestCoverage and FloatImage::scaleAlphaToCoverage: - https://code.google.com/p/nvidia-texture-tools/source/browse/trunk/src/nvimage/FloatImage.cpp ) -*/ - -#ifndef STBIR_INCLUDE_STB_IMAGE_RESIZE_H -#define STBIR_INCLUDE_STB_IMAGE_RESIZE_H - -#ifdef _MSC_VER -typedef unsigned char stbir_uint8; -typedef unsigned short stbir_uint16; -typedef unsigned int stbir_uint32; -#else -#include -typedef uint8_t stbir_uint8; -typedef uint16_t stbir_uint16; -typedef uint32_t stbir_uint32; -#endif - -#ifndef STBIRDEF -#ifdef STB_IMAGE_RESIZE_STATIC -#define STBIRDEF static -#else -#ifdef __cplusplus -#define STBIRDEF extern "C" -#else -#define STBIRDEF extern -#endif -#endif -#endif - -////////////////////////////////////////////////////////////////////////////// -// -// Easy-to-use API: -// -// * "input pixels" points to an array of image data with 'num_channels' channels (e.g. RGB=3, RGBA=4) -// * input_w is input image width (x-axis), input_h is input image height (y-axis) -// * stride is the offset between successive rows of image data in memory, in bytes. you can -// specify 0 to mean packed continuously in memory -// * alpha channel is treated identically to other channels. -// * colorspace is linear or sRGB as specified by function name -// * returned result is 1 for success or 0 in case of an error. -// #define STBIR_ASSERT() to trigger an assert on parameter validation errors. -// * Memory required grows approximately linearly with input and output size, but with -// discontinuities at input_w == output_w and input_h == output_h. -// * These functions use a "default" resampling filter defined at compile time.

/* stb_image_resize - v0.97 - public domain image resizing
by Jorge L Rodriguez (@VinoBS) - 2014
http://github.com/nothings/stb
Written with emphasis on usability, portability, and efficiency. (No
SIMD or threads, so it be easily outperformed by libs that use those.)
Only scaling and translation is supported, no rotations or shears.
Easy API downsamples w/Mitchell filter, upsamples w/cubic interpolation.
COMPILING & LINKING
In one C/C++ file that #includes this file, do this:
#define STB_IMAGE_RESIZE_IMPLEMENTATION
before the #include. That will create the implementation in that file.
QUICKSTART
stbir_resize_uint8( input_pixels , in_w , in_h , 0,
output_pixels, out_w, out_h, 0, num_channels)
stbir_resize_float(...)
stbir_resize_uint8_srgb( input_pixels , in_w , in_h , 0,
output_pixels, out_w, out_h, 0,
num_channels , alpha_chan , 0)
stbir_resize_uint8_srgb_edgemode(
input_pixels , in_w , in_h , 0,
output_pixels, out_w, out_h, 0,
num_channels , alpha_chan , 0, STBIR_EDGE_CLAMP)
// WRAP/REFLECT/ZERO
FULL API
See the "header file" section of the source for API documentation.
ADDITIONAL DOCUMENTATION
SRGB & FLOATING POINT REPRESENTATION
The sRGB functions presume IEEE floating point. If you do not have
IEEE floating point, define STBIR_NON_IEEE_FLOAT. This will use
a slower implementation.
MEMORY ALLOCATION
The resize functions here perform a single memory allocation using
malloc. To control the memory allocation, before the #include that
triggers the implementation, do:
#define STBIR_MALLOC(size,context) ...
#define STBIR_FREE(ptr,context) ...
Each resize function makes exactly one call to malloc/free, so to use
temp memory, store the temp memory in the context and return that.
ASSERT
Define STBIR_ASSERT(boolval) to override assert() and not use assert.h
OPTIMIZATION
Define STBIR_SATURATE_INT to compute clamp values in-range using
integer operations instead of float operations. This may be faster
on some platforms.
DEFAULT FILTERS
For functions which don't provide explicit control over what filters
to use, you can change the compile-time defaults with
#define STBIR_DEFAULT_FILTER_UPSAMPLE STBIR_FILTER_something
#define STBIR_DEFAULT_FILTER_DOWNSAMPLE STBIR_FILTER_something
See stbir_filter in the header-file section for the list of filters.
NEW FILTERS
A number of 1D filter kernels are used. For a list of
supported filters see the stbir_filter enum. To add a new filter,
write a filter function and add it to stbir__filter_info_table.
PROGRESS
For interactive use with slow resize operations, you can install
a progress-report callback:
#define STBIR_PROGRESS_REPORT(val) some_func(val)
The parameter val is a float which goes from 0 to 1 as progress is made.
For example:
static void my_progress_report(float progress);
#define STBIR_PROGRESS_REPORT(val) my_progress_report(val)
#define STB_IMAGE_RESIZE_IMPLEMENTATION
#include "stb_image_resize.h"
static void my_progress_report(float progress)
{
printf("Progress: %f%%\n", progress*100);
}
MAX CHANNELS
If your image has more than 64 channels, define STBIR_MAX_CHANNELS
to the max you'll have.
ALPHA CHANNEL
Most of the resizing functions provide the ability to control how
the alpha channel of an image is processed. The important things
to know about this:
1. The best mathematically-behaved version of alpha to use is
called "premultiplied alpha", in which the other color channels
have had the alpha value multiplied in. If you use premultiplied
alpha, linear filtering (such as image resampling done by this
library, or performed in texture units on GPUs) does the "right
thing". While premultiplied alpha is standard in the movie CGI
industry, it is still uncommon in the videogame/real-time world.
If you linearly filter non-premultiplied alpha, strange effects
occur. (For example, the 50/50 average of 99% transparent bright green
and 1% transparent black produces 50% transparent dark green when
non-premultiplied, whereas premultiplied it produces 50%
transparent near-black. The former introduces green energy
that doesn't exist in the source image.)
2. Artists should not edit premultiplied-alpha images; artists
want non-premultiplied alpha images. Thus, art tools generally output
non-premultiplied alpha images.
3. You will get best results in most cases by converting images
to premultiplied alpha before processing them mathematically.
4. If you pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED, the
resizer does not do anything special for the alpha channel;
it is resampled identically to other channels. This produces
the correct results for premultiplied-alpha images, but produces
less-than-ideal results for non-premultiplied-alpha images.
5. If you do not pass the flag STBIR_FLAG_ALPHA_PREMULTIPLIED,
then the resizer weights the contribution of input pixels
based on their alpha values, or, equivalently, it multiplies
the alpha value into the color channels, resamples, then divides
by the resultant alpha value. Input pixels which have alpha=0 do
not contribute at all to output pixels unless _all_ of the input
pixels affecting that output pixel have alpha=0, in which case
the result for that pixel is the same as it would be without
STBIR_FLAG_ALPHA_PREMULTIPLIED. However, this is only true for
input images in integer formats. For input images in float format,
input pixels with alpha=0 have no effect, and output pixels
which have alpha=0 will be 0 in all channels. (For float images,
you can manually achieve the same result by adding a tiny epsilon
value to the alpha channel of every image, and then subtracting
or clamping it at the end.)
6. You can suppress the behavior described in #5 and make
all-0-alpha pixels have 0 in all channels by #defining
STBIR_NO_ALPHA_EPSILON.
7. You can separately control whether the alpha channel is
interpreted as linear or affected by the colorspace. By default
it is linear; you almost never want to apply the colorspace.
(For example, graphics hardware does not apply sRGB conversion
to the alpha channel.)
