Required attribution
When redistributing this directory (or any binary that embeds the SVG files within), credit must be given to Streamline and a link to the licence must be reachable to the user. The exact wording is flexible — any of the following satisfies the obligation:
Icons by Streamline, CC BY 4.0.
Symbolic icons: © Streamline, distributed under CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/).
The full Debian-style attribution lives in the top-level
debian/copyright of the ltk source
tree under the Files: themes/default/icons/catalogue/* paragraph.
Modifications
Some of the SVG files in this directory have been modified from
their upstream Streamline form, but the set of modifications is
not tracked per icon. Common edits that get applied across icon
imports of this kind include any of: viewBox normalisation, removal
or normalisation of inline fill / stroke attributes (so the
runtime theme::tint_symbolic pass controls the final colour),
ID / class renames, path simplification at small chrome sizes — but
which of these landed on which file is not recorded.
Treat any file in this directory as potentially differing from the upstream Streamline distribution. Anyone needing a pristine copy of the original glyphs should fetch them from https://www.streamlinehq.com/icons/core-line-free rather than rely on this directory's contents being byte-identical to the upstream release.
This declaration satisfies CC BY 4.0 §3(a)(1)(B) by indicating that modifications were made, even though it does not enumerate them per file. The CC BY 4.0 specification requires the modifications to be indicated, not itemised; a directory-wide declaration is the recognised pattern for asset imports where the diff against upstream was not tracked at integration time.
In addition, ltk performs run-time symbolic tinting through
theme::tint_symbolic on the rasterised RGBA pixel data; this is a
transformation of the rendered output and is not a modification
of the SVG files on disk. The on-disk modifications above are what
§3(a)(1)(B) requires us to declare; the runtime tint is independent.
How licensing applies to the rest of the theme
Files under themes/default/branding/ (wallpapers, lockscreens,
launcher logos, brand wordmark variants), themes/default/icons/apps/
(per-application icons) and themes/default/icons/app-default.svg
(the unknown-app fallback) are original artwork by Liberux Labs
distributed under the same LGPL-2.1-only terms as the rest of the
toolkit. They are not covered by the CC BY 4.0 declaration above.
Themes that fork the default tree should preserve the split: re-license
your own artwork freely, but the contents of this catalogue/ directory
remain CC BY 4.0 with attribution to Streamline.
