* GN: guard tools (except fiddle) by skia_enable_tools.Gravatar mtklein2016-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our tools use third-party libraries pretty freely, some of which may not be available in other GN environments (e.g. Fuchsia). Most can also not function when Skia is built as a shared library. fiddle stands alone as the exception to both those points: it depends on only Skia, and works fine with both a shared or static library. So guard everything but fiddle with this flag skia_enable_tools, disabled when we're building for Fuchsia or when we're build a shared library. This CL has a couple of little tweaks to Fiddle to keep it working: - divorce it from :tool_utils, instead just building SkForceLinking.cpp itself; - fix up a buggy rebase_path() that was accidentally working when we depended on :tool_utils; - drop test_only: it now only requires production-code dependencies. The SkImageEncoder Create* methods need to be SK_API if we want SkForceLinking to work across .so's. Without this, SkForceLinking needs to be part of Skia; it can't be part of the application using Skia. The rest is mostly just a re-indent under if (skia_enable_tools), courtesy of gn format.

* Separate core and images project.Gravatar scroggo@google.com2013-05-31
SkImage calls functions on SkImageDecoder and SkImageEncoder. This is desired behavior, and it is also desired to include SkImage as a part of core. In order to keep core from depending on images, update SkImageDecoder_empty.cpp to implement all of SkImageDecoder and SkImageEncoder. This file will be built by chrome (in https://codereview.chromium.org/15960015). Move force_linking from SkImageDecoder.cpp to its own file. It must be called to force linking with the image decoders if desired. Call the function in tools that need it: sk_image render_pictures render_pdfs sk_hello filter bench_pictures debugger SkImageDecoder: Derive from SkNoncopyable, instead of duplicating its hiding of constructors. skhello: Return rather than trying to write a null SkData to the stream. Revert "Hamfistedly removed core dependence on images" (commit 0f05f682a90bc125323677abf3476e1027d174f5) and "Move SkImage::encode to SkImage_Codec.cpp." (commit 83e47a954d0bf65439f3d9c0c93213063dd70da3.) These two commits were temporary fixes that this change cleans up. SkSnapshot.cpp: Check for a NULL encoder returned by SkImageEncoder::Create.
