This is now part of the API and thus -+// hard to change without causing breakage. As a result, the various image -+// loaders all have certain limits on image size; these differ somewhat -+// by format but generally boil down to either just under 2GB or just under -+// 1GB. When the decoded image would be larger than this, stb_image decoding -+// will fail. -+// -+// Additionally, stb_image will reject image files that have any of their -+// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, -+// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, -+// the only way to have an image with such dimensions load correctly -+// is for it to have a rather extreme aspect ratio. Either way, the -+// assumption here is that such larger images are likely to be malformed -+// or malicious. If you do need to load an image with individual dimensions -+// larger than that, and it still fits in the overall size limit, you can -+// #define STBI_MAX_DIMENSIONS on your own to be something larger. -+// - // =========================================================================== - // - // UNICODE: -@@ -272,11 +310,10 @@ RECENT REVISION HISTORY: - // - // iPhone PNG support: - // --// By default we convert iphone-formatted PNGs back to RGB, even though --// they are internally encoded differently.
