# ImageMagick
|
|
|
|
ImageMagick 7 image manipulation toolkit: `magick`, `convert`,
|
|
`identify`, `mogrify`, `montage`, ... plus the MagickCore / MagickWand /
|
|
Magick++ libraries.
|
|
|
|
- Upstream: https://imagemagick.org/ (source: https://github.com/ImageMagick/ImageMagick)
|
|
- License: ImageMagick License (Apache-2.0 derived)
|

|
|
## How it is built
|
|
|
|
Standard autotools from the sha-pinned GitHub tag tarball; the default
|
|
modbuild hooks do `./configure --prefix=$PREFIX && make && make install`.
|
|
Built with the gcc/12.3.0 module (also a runtime dep — Magick++ needs
|
|
its libstdc++ on RHEL8). Version keys are the full upstream tag
|
|
(`7.1.2-30`), which the download URL uses as `${V}`.
|
|
|
|
Image-format delegates (PNG, JPEG, TIFF, ...) auto-enable from the
|
|
`-devel` RPMs present on the build host. If a needed format is missing,
|
|
install the RPM (e.g. `libpng-devel libjpeg-turbo-devel libtiff-devel`)
|
|
and rebuild.
|
|
|
|
## Building on Ra
|
|
|
|
```sh
|
|
module use unstable && module load modbuild/2.1.3
|
|
cd ImageMagick
|
|
modbuild build \
|
|
--tmpdir=/das/work/p21/p21515/.cache/Pmodules \
|
|
--distdir=/das/work/p21/p21515/.cache/Pmodules \
|
|
7.1.2-30
|
|
module use MX unstable && module load ImageMagick/7.1.2-30
|
|
```
|
|
|
|
## Verifying the install
|
|
|
|
```sh
|
|
which magick # -> /opt/psi/MX/ImageMagick/7.1.2-30/bin/magick
|
|
magick -version # version + enabled features
|
|
magick -list format | head # delegates that got enabled
|
|
magick rose: /tmp/rose.png # end-to-end: writes a PNG (needs libpng delegate)
|
|
```
|
|
|
|
## Adding a new version
|
|
|
|
Pick the tag from https://github.com/ImageMagick/ImageMagick/tags, add
|
|
version + tarball sha256 in `files/config.yaml` (`sha256sum` the
|
|
downloaded tag tarball), then build as above.
