ImageMagick 7 port to Android

ImageMagick 7 port to Android.

Binaries

• latest binaries for arm-v7a/arm64-v8a/x86/x86-64: v0.4.7083.17
• latest binaries for mips32/misp64 and armv5: v0.4.70710
• release number pattern is follow: vX.X.YYYYY.ZZ, where X.X - major\minor number for build, YYYYY - ImageMagick version(i.e. 70735 is 7.0.7.35), ZZ - NDK version (i.e. 17b1 - NDK17beta1)

Last changes

• return build of magick utility by default
• Image Magick updated to latest version (7.0.8.3)
• clang toolchain supported. required Android NDK r15 to build (early versions had issues with OpenMP support)
• NDK r17 and later drop support for mips32/64 and arm v5.
• all binaries moved to github release section

General

• MagickCore 7.0.8.3 (actual at 2018.06.28)
• MagickWand
• 3rd party libs actual at 2017.03
• OpenMP build by default (with gcc 4.9 and clang 5.0.3)
• Magick++ disable due to crash, sources removed (looks like nobody used it anyway)

Why?

• ImageMagick7 is not fully compatible with early(ImageMagick6) version
• build with OpenMP (DistortImage on 4core/armv7a get 3.597 speedup factor)
• smaller binary size in case of using only MagickCore

Test for ImageMagick 7/Android

• test app code exist in ./prj/IM7Test. It can be used as example for C\C++\qmake project.
• demonstrtate OpenMP advantage on multi-core CPU in modern smartphones
• GUI version published to google play for armv7 and x86

For C/C++ users

• number of file formats disabled for now(exr, svg, jpeg2000, webp) and not planed to enable back (looks like nobody use it)
• MagickWand added as separate Shared Object - need to be linked separately
• If you need additional file formats, ICU, plz use cherryleafroad port(currently only for amr64)

For Java users

• Please, use cherryleafroad port of ImageMagick7 with optional JMagick support (currently only for amr64)
• Please, use paulasiimwe port of ImageMagick 6 - it's include Java interface (JMagick)

Rebuild

• change directory to Android_ImageMagick7/jni
• run path-to-your-ndk/ndk-build -j 4
• or set up envinronment variable ANDROID_SDK_PATH and run gccBuild/clangBuild.sh

OpenMP

• depends from Application.mk details
• Android NDK(current version 17b1) support OpenMP with both clang and gcc toolchain (binaries provided for both)

OpenCL

• can me much faster on certain operation (blur etc)
• not working correctrly for now
