WordPress.org

Prerequisite

1. PHP 5.x with GD extension (Please visit offical site if ancient version using PHP4 is needed)
2. ImageMagick >= 6.3.5-7 (due to usage of -alpha option). Version later than 6.3.9-6 is preferred, since a bug about detecting PostScript transparency is fixed.
3. GhostScript (Usually pre-installed on Linux. Under Windows, download prepackaged installer from official site )
4. Music rendering programs must also be installed on the same machine web server is running. For example, to support Lilypond fragments, Lilypond >= 2.8.1 must be installed in web server. Most notations require explicit program to render, except GUIDO notation which fetches remote images instead. Refer to installation page for more detail.

New install

1. Install any prerequisite programs as noted above.
2. Extract archive, and copy 'scorerender' folder to wp-content/plugins/, keeping the folder structure intact.
3. Login to WordPress and enable the plugin in admin interface.
4. Configure ScoreRender under the ScoreRender tab of the Options page.

5. In Option -> Writing, check if this option is turned on:

   "WordPress should correct invalidly nested XHTML automatically"

   It must be turned off if you intent to render Lilypond and Mup fragments, since this option will convert "<<" and ">>" into "< <" and "> >" correspondingly, thus destroying the music content and cause render error.

Upgrade

1. Deactivate the plugin in WordPress admin page.
2. Remove the whole plugin folder.
3. Upload new plugin and activate again.
