/**
* Native bindings to stb_image_resize.h from the stb library.
*
*
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.
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:
*
*
*
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 average of 1% opaque bright green and 99% opaque
* 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.)
*
Artists should not edit premultiplied-alpha images; artists want non-premultiplied alpha images. Thus, art tools generally output non-premultiplied
* alpha images.
*
You will get best results in most cases by converting images to premultiplied alpha before processing them mathematically.
*
If you pass the flag {@link #STBIR_FLAG_ALPHA_PREMULTIPLIED 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.
*
If you do not pass the flag {@link #STBIR_FLAG_ALPHA_PREMULTIPLIED 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
* {@code alpha=0} do not contribute at all to output pixels unless all of the input pixels affecting that output pixel have {@code alpha=0},
* in which case the result for that pixel is the same as it would be without {@link #STBIR_FLAG_ALPHA_PREMULTIPLIED FLAG_ALPHA_PREMULTIPLIED}. However, this is only true for input images
* in integer formats. For input images in float format, input pixels with {@code alpha=0} have no effect, and output pixels which have
* {@code 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.)
*
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.)
*
