Utils for TinyWorld

JRE distros

Supported JRE distributions are available here. They are included in the portable and AppImage packages of TinyWorld.

ImageMagick with HEIF/HEIC support

Linux x64/arm64 and Windows x64 static binaries of ImageMagick 7.1.0 with HEIF/HEIC support can be found here.

Currently, TinyWorld only relies on ImageMagick for thumbnails generation from HEIF photos.

On macOS, install ImageMagick with Homebrew (HEIF/HEIC support is enabled by default):

brew install imagemagick

Linux build

Linux binary has been compiled from source as existing packages do not come with HEIC support.

Instructions to build static binary:

# Install libs for HEIF (HEIC) support
$ sudo apt install libjpeg-dev libheif-dev libheif1

# Clone latest tag
$ git clone --depth 1 --branch 7.1.0-46 https://github.com/ImageMagick/ImageMagick.git
$ cd ImageMagick

# Configure build to generate static binaries. Enable HEIC support
$ ./configure --enable-static=yes --enable-shared=no --prefix=/usr --with-jpeg=yes --with-heic=yes --without-magick-plus-plus --without-perl --with-quantum-depth=16

# Compile
$ make

# Install in a temporary folder
$ mkdir -p /tmp/MyIM
$ make install DESTDIR=/tmp/MyIM

# Check HEIC support is enabled
# Make sure both 'jpeg' and 'heic' are listed in 'Delegates (built-in)'
$ cd /tmp/MyIM/usr/bin
$ ./magick -version

WorlWind Cache for TinyWorld

This repo hosts a NASA WorldWind cache to use as a starter on any WorldWind-based application, e.g. TinyWorld. It helps to get first tiles, all the most if you don't have a good Internet connection.

The cache is available for several tiles format:

• DDS
• JPEG and PNG (depends on the layer)

For each layer, tiles format is defined via the ImageFormat tag in the corresponding layer's config file (e.g. of layers' config files: Earth/BMNGWMSLayer2.xml, Earth/LandsatI3WMSLayer2.xml).

WorlWind Cache starter can be downloaded here.
