Eugene Golushkov 69a7dd32a8 stb_image: fix building by MSVC for Windows 10 on ARM 2021-07-03 00:59:26 -07:00
Fabian Giesen a0231a9e94 stb_image: Key Win32 UTF-8 support off _WIN32 not _MSC_VER 
So that it also works on MinGW.

Fixes issue #729.
 2021-07-03 00:46:04 -07:00
Fabian Giesen e3a63f3793 stb_image: Fix wrong buffer sizes passed to MultiByteToWideChar 
Fixes issue #772.
 2021-07-03 00:38:30 -07:00
Fabian Giesen 3870fb6a93 stb_image: Reorder format test sequence 
Put the formats that start with a clear magic number first,
the dodgy ones that don't have much of a distinctive header
should be tested for later after we've ruled out the clearer
ones.

Fixes issue #787, hopefully. (Never got a clean repro.)
 2021-07-02 23:06:44 -07:00
Fabian Giesen e795306bbc stb_image: Document image size limits 
Both the buffer size limits and the image dimension limits.

Fixes issue #672.
 2021-07-02 22:52:15 -07:00
Fabian Giesen ba739e54ed readme: Add "how to use these libs" section 
Try to be a bit more explicit still.

Fixes issue #903, or so I hope.
 2021-07-02 22:31:41 -07:00
Fabian Giesen d343a29fe6 stb_image: Erorr in BMP should error, not assert. 
There was both the assert and the error check; should just be
the error check.

Fixes issue #881 (or rather, part of it).

Fabian Giesen 41e93836d9 stb_image: UB fix in stbi__get32le 
Need to do the second-part shift on uint32 not int.
 2021-07-02 21:57:25 -07:00
Fabian Giesen cf00c67c57 stb_image: Update comment 
As per recent patches, we do support 16-bit PNMs.
 2021-07-02 21:38:44 -07:00
Fabian Giesen 48632c1752 stb_image: Avoid left-shifts of signed values 
It's implementation-specified behavior. Writing this code and then
relying on compiler strength reduction to turn it back into shifts
feels extremely silly but it is what it is.

Fixes issue #1097.
 2021-07-02 21:09:11 -07:00
Fabian Giesen 026013546c stb_image: Avoid shift of signed values in extend_receive 
Use an equivalent formulation that has sgn=0 or 1, not 0 or -1.
This avoids right-shifting signed values, at least in this place.

Fixes issue #1061.
 2021-07-02 20:59:22 -07:00
Fabian Giesen 4d067e8b2b stb_image, stb_image_write: Fix compare sign warnings 
For the stb_image fix, also replace the magic 288 with a more
descriptive name while I'm at it.

Fixes #1100
 2021-07-02 18:42:01 -07:00
Fabian Giesen 1d7bf85877 stb_image: Fix lrot definition, small extend_receive tweak 
Define lrot in a way that doesn't involve UB when n==0.
Also, the previous patch ensures that n <= 15 for all callers
of stbi__extend_receive, so can remove the (less restrictive)
bounds check for 0 <= n < 17 (the bounds of stbi__bmask)
entirely.

Fixes issue #1065.
 2021-07-02 18:28:41 -07:00
Fabian Giesen a3f2897b85 stb_image: Fix bug on JPEGs with malformed DC deltas 
extend_receive implicitly requires n <= 15 (code length);
the maximum that actually makes sense for 8-bit baseline JPEG is
11, but 15 is the natural limit for us because the AC coding path
stores the number of magnitude bits in a nibble.

Check that DC delta bits are in range before attempting to call
extend_receive.

Fixes issue #1108.
 2021-07-02 18:10:49 -07:00
Fabian Giesen 50072f6658 stb_image: Check results of all mallocs. 
A few were missing. Make sure to always report ouf-of-memory
errors.

Fixes issue #1056.

Jacko Dirks 655b2b1f06 stb_image.h: Suppress warnings about out_size, delay_size 
These two variables are unused on some targets, resulting in
warnings. Add STBI_NOTUSED around them to suppress those
warnings.
 2021-07-01 17:24:12 -07:00

Fabian Giesen 309322ae4a stb_truetype: Turn codepoint assert into error check 
Fixes the bug covered by PR #1066, but with a slightly different
fix that's hopefully a bit clearer.

Doj 0755e6a76f stb_sprintf: fix stbsp_ddtoS64 macro

variable that it actually gets instantiated with the
one time it is used).

Valentin Lenhart 073114d111 stb_sprintf.h: stdlib.h is not needed 
va_arg() is in stdarg.h, which is already being included

Fabian Giesen 9a9c937f68 stb_dxt: Remove dithering support. 
Keep STB_DXT_DITHER so as not to break existing code that tries
to enable it, but just leave it permanently off. I originally
introduced it somewhat superstitiously because of the RGB565
endpoint resolution but it never improved either perceptual quality
or objective quality metrics, and the code is appreciably simpler
without it.

Fabian Giesen 425c4d8b31 stb_dxt: Better error calc for single-color table 
Don't truncate error as aggressively; easily done, but wanted
to keep it separate from the previous change.
 2021-07-01 16:24:09 -07:00
Alan Hickman d84beeeff3 stb_dxt: Initialize tables at compile time 
Also fix a "potentially uninitialized variable" warning.

This is a modified version of Alan's original PR that keeps the
table generator in the file (in case there's interest) and also
replaces the expand[] tables with math, since it's trivial.

Fixes issue #1117.
 2021-07-01 16:19:17 -07:00
Michael Aganier 40d7e47896 stb_sprintf: add attribute format to variadic functions 
This allows for compiler verification of the format string
just like printf.
 2021-07-01 15:39:42 -07:00
Fabian Giesen 05e1efab3d Move stb.h to deprecated. 
It was never designed to be used by anyone but Sean and has
numerous problems; new code should definitely not be using
this.
