Neil Bickford 47164e4086 Add checks for signed integer overflow; further guard against cases where stbi__grow_buffer_unsafe doesn't read all bits required. 2022-11-29 00:36:36 -08:00

Fabian Giesen 5ba0baaa26 stb_image: Reject fractional JPEG component subsampling ratios 
The component resamplers are not written to support this and I've
never seen it happen in a real (non-crafted) JPEG file so I'm
fine rejecting this as outright corrupt.

Fixes issue #1178.

Sean Barrett 4bb337ddf0 test including stb_c_lexer header independnet of implementation 2021-07-09 05:36:53 -07:00
Fabian Giesen 2b667e4d30 stb_rect_pack: Several minor fixes 
1. Always use large rects mode to avoid definition of stbrp_coord
   in header file depending on implementation #defines
2. Expose STBRP__MAXVAL to users
3. Fix value of STBRP__MAXVAL for large rect mode (stbrp_coord
   is a 32-bit int, so needs to be <=0x7fffffff, 0xffffffff
   doesn't work)
4. Add comment at the top about which #define to set to get the
   implementation.

Fixes issue #1143, or rather, replaces that pull request.

Fabian Giesen 013884b53b stb_sprintf: Fix string length calc 
Factor out string length computation into helper func, comment
it a bit more, always use a limit to avoid 32b unsigned overflow,
and avoid reading past the bounds of non-0-terminated strings given
with specified precision.

Fixes issue #966.
