Unimage Native

Used by Unimage Unity.
It can load png/jpeg/webp/bmp/tga/gif in to memory, and provides some simple operations.

Building

1. Configure environment

export VCPKG_DIR=/path/to/vcpkg
export TRIPLET=... # triplet you want to build for

# If you want to build for Android:
export ANDROID_NDK_HOME=/path/to/ndk # set your android ndk path

# If it is the first time you build Unimage, add a new triplet to build with bitcode:
cp ./scripts/arm64-ios-bitcode.cmake $VCPKG_DIR/triplets/community/

Or you are using PowerShell

$VCPKG_DIR="/path/to/vcpkg"
$TRIPLET="..." # triplet you want to build for

# If you want to build for Android:
$ANDROID_NDK_HOME="/path/to/ndk" # set your android ndk path
$env:ANDROID_NDK_HOME=$ANDROID_NDK_HOME

#If it is the first time you build Unimage, add a new triplet to build with bitcode
cp ./scripts/arm64-ios-bitcode.cmake $VCPKG_DIR/triplets/community/

If you want to build for iOS, you need to use triplet arm64-ios-bitcode

2. Install dependencies

pushd $VCPKG_DIR
./vcpkg install "stb:$TRIPLET"
./vcpkg install "libwebp:$TRIPLET"
./vcpkg install "libjpeg-turbo:$TRIPLET"
popd

3. Generate for special platform:

1) Windows:

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=$VCPKG_DIR/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release
msbuild ALL_BUILD.vcxproj

2) Linux:

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=$VCPKG_DIR/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release
make # or use ninja to build

3) macOS:

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=$VCPKG_DIR/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release
make

4) iOS

mkdir build
cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=$VCPKG_DIR/scripts/buildsystems/vcpkg.cmake -DCMAKE_BUILD_TYPE=Release -DVCPKG_TARGET_TRIPLET=arm64-ios-bitcode -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_ARCHITECTURES=arm64
make

5) Android

# Build for ARM
mkdir build-arm
pushd build-arm
cmake .. -DCMAKE_BUILD_TYPE=Release -DVCPKG_TARGET_TRIPLET=arm-android -DANDROID_ABI=armeabi-v7a -DVCPKG_CMAKE_SYSTEM_NAME=Android -DCMAKE_SYSTEM_NAME=Android -DCMAKE_TOOLCHAIN_FILE=$VCPKG_DIR/scripts/buildsystems/vcpkg.cmake -DVCPKG_CHAINLOAD_TOOLCHAIN_FILE=$ANDROID_NDK_HOME/build/cmake/android.toolchain.cmake -DCMAKE_MAKE_PROGRAM=$ANDROID_NDK_HOME/prebuilt/windows-x86_64/bin/make.exe -G "Unix Makefiles"
