* [core] introduce Blob for compressed and uncompressed dataupstream/blobKonstantin Käfer2018-02-211-3/+3
| | | | | | | | | | | | - Blob is a wrapper type for a shared_ptr<const string> that has accessor functions for getting compressed and uncompressed data - Moved util::writeFile, util::readFile, util::compress, util::uncompress, decodeImage, and encodePNG to the Blob interface - Added Blob support to Request and file sources - Added Blob support to VectorTile objects - Added support for gzip decoding to util::uncompress - We're no longer compressing WebP, PNG, and JPEG data when storing in the OfflineDatabase - Android's HTTPRequest returns compressed Blobs by default One caveat is that our previous decompress function didn't support gzip, so once users upgrade to this version, their offline cache may contain both zlib-compressed data and gzip-compressed data, but older versions won't be able to decompress gzip data. On the other hand, we don't support downgrading SDKs anyway, so this shouldn't be a problem. To be on the safe side, we could bump the user_version of the SQLite DB.

* [core] Make Image saferJohn Firebaugh2017-02-141-4/+61
| | | | | | Provide Image::copy, which handles copying rectangles from a source to a destination, with thorough bounds checking. Also fixes an indexing error in SpriteAtlas, where the top row of pixels in a wrapped image was copied from the wrong source row.

* Revert "Revert WebP support due to broken builds"Bruno de Oliveira Abinader2016-01-201-0/+5
| | | | | | | This reverts commit 6709bdcacd5a45a10b554f3f225206c9494e5e43. There was an issue with the script that removes '-lwebp' from WebP linker flags, since we're statically linking. This is now fixed.

* [linux] Added WebP tile supportBruno de Oliveira Abinader2016-01-191-0/+5
| | | | | | | - Android support is currently disabled due to a libwebp build issue. - iOS and OS X support will appear after the next Mapbox iOS SDK release. Related: #https://github.com/mapbox/mapbox-gl-native/issues/2354

* [core] Fix image type of Map::renderStillJohn Firebaugh2015-11-251-1/+1
| | | | | | | It's a premultiplied image. This implies that we were misusing encodePNG in most cases, as we were passing premultiplied pixels which were then interpreted as unmultiplied. I changed encodePNG to accept premultipled pixels, and unpremultiply in the implementations.
