DigitalSlideArchive.vips

This is an Ansible role that installs VIPS image processing software with reliable OpenSlide support.

On Ubuntu 14.04, there is a bug in VIPS that may prevent OpenSlide from opening some images correctly. This role addresses that issue by installing the necessary OpenSlide dependencies for VIPS.

Requirements

You should run this on a fresh Ubuntu 14.04 or 16.04 system.

Role Variables

You can change the following variables if needed:

• vips_libtiff_path: Location to download and build LibTIFF.
• vips_openjpeg_path: Location to download and build OpenJPEG.
• vips_openslide_path: Location to download and build OpenSlide.
• vips_path: Location to download and build VIPS.

You can also change these variables, but you probably won't need to:

• vips_libtiff_version: Version identifier for fetching LibTIFF.
• vips_openjpeg_version: Version identifier for fetching OpenJPEG.
• vips_openslide_version: Version identifier for fetching OpenSlide.
• vips_version: Version identifier for fetching VIPS.
• build_parallelism: Number of jobs to run simultaneously during the build process.
