DigitalSlideArchive.vips

An Ansible role to install VIPS image processing software with bug-free OpenSlide support.

On Ubuntu 14.04, VIPS contains a bug where OpenSlide does not open some images properly. This role installs VIPS's OpenSlide dependencies to reliably work around that bug.

Requirements

This is intended to be run on a clean Ubuntu 14.04 or 16.04 system.

Role Variables

You may want to override the variables:

• vips_libtiff_path: Path to fetch and build LibTIFF.
• vips_openjpeg_path: Path to fetch and build OpenJPEG.
• vips_openslide_path: Path to fetch and build OpenSlide.
• vips_path: Path to fetch and build VIPS.

You can (but probably won't need to) override the variables:

• vips_libtiff_version: Git commit-ish for fetching LibTIFF.
• vips_openjpeg_version: Git commit-ish for fetching OpenJPEG.
• vips_openslide_version: Git commit-ish for fetching OpenSlide.
• vips_ersion: Git commit-ish for fetching VIPS.
• build_parallelism: The number of parallel jobs to build with.
