credit third party code
the slice-by-16 crc32 comes from Arjun Barrett's gist, parts of the JPEG codec are translated from libjpeg (IJG) and follow pdf.js' decoder, the glyph rasterizer is translated from font-rs. THIRD_PARTY_NOTICES.md lists them with their licenses (full Apache-2.0 text and libjpeg's README in licenses/), the derived files say so in /*! */ headers that survive the build, which used to strip fflate's notice from dist Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Ljnxm1Qjrocq1izGajLx8J

81+
The deflate/inflate implementation is derived from [fflate](https://github.com/101arrowz/fflate) and the CRC-32 from
82+
[Fast CRC32 in JavaScript](https://gist.github.com/101arrowz/e58695f7ccfdf74f60ba22018093edea), both by Arjun Barrett.
83+
The JPEG codec is based in part on the work of the Independent JPEG Group (libjpeg) and on
84+
[pdf.js](https://github.com/mozilla/pdf.js), the glyph rasterizer is translated from
85+
[font-rs](https://github.com/raphlinus/font-rs). See [THIRD_PARTY_NOTICES.md](THIRD_PARTY_NOTICES.md) for their licenses.

## libjpeg / libjpeg-turbo
42+
43+
This software is based in part on the work of the Independent JPEG Group.
44+
45+
The JPEG codec translates parts of libjpeg (as shipped by libjpeg-turbo) to TypeScript: the integer inverse DCT
46+
(`jidctint.c`), the floating point forward DCT (`jfdctflt.c`), fancy upsampling (`jdsample.c`), the YCbCr to RGB
47+
tables (`jdcolor.c`), the progressive AC refinement (`jdphuff.c`) and the optimal Huffman table generation
48+
(`jcphuff.c`/`jchuff.c`). The translations were rewritten for TypeScript's numbers and typed arrays; the rest of the
49+
codec is ImageScript's own. libjpeg's README with its copyright and terms is included unaltered as
50+
[licenses/README.ijg](licenses/README.ijg).

The scan decoder of `src/codecs/jpeg.ts` follows the structure of pdf.js' `src/core/jpg.js` (block and MCU layout,
72+
one decode function per scan type). The `Rasterizer` class in `src/render/text.ts` is a translation of font-rs'
73+
`Raster` from Rust to TypeScript (`draw_line`, `draw_quad`, `accumulate`); its `cubic` method is adapted from
74+
`draw_quad`. The full license text is in [licenses/Apache-2.0.txt](licenses/Apache-2.0.txt).

102+
that You distribute, all copyright, patent, trademark, and
103+
attribution notices from the Source form of the Work,
104+
excluding those notices that do not pertain to any part of
105+
the Derivative Works; and
106+
107+
(d) If the Work includes a "NOTICE" text file as part of its
108+
distribution, then any Derivative Works that You distribute must
109+
include a readable copy of the attribution notices contained

111+
pertain to any part of the Derivative Works, in at least one
112+
of the following places: within a NOTICE text file distributed
113+
as part of the Derivative Works; within the Source form or
114+
documentation, if provided along with the Derivative Works; or,

or as an addendum to the NOTICE text from the Work, provided
121+
that such additional attribution notices cannot be construed
122+

123+
124+
You may add Your own copyright statement to Your modifications and
125+
may provide additional or different license terms and conditions
126+
for use, reproduction, or distribution of Your modifications, or

reproduction, and distribution of the Work otherwise complies with

5. Submission of Contributions. Unless You explicitly state otherwise,
132+
any Contribution intentionally submitted for inclusion in the Work
133+
by You to the Licensor shall be under the terms and conditions of
134+
this License, without any additional terms or conditions.
135+
Notwithstanding the above, nothing herein shall supersede or modify
136+
the terms of any separate license agreement you may have executed
137+
with Licensor regarding such Contributions.
138+
139+
6. Trademarks. This License does not grant permission to use the trade
140+
names, trademarks, service marks, or product names of the Licensor,
141+

origin of the Work and reproducing the content of the NOTICE file.

145+
agreed to in writing, Licensor provides the Work (and each
146+
Contributor provides its Contributions) on an "AS IS" BASIS,
147+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
148+
implied, including, without limitation, any warranties or conditions
149+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
150+
PARTICULAR PURPOSE. You are solely responsible for determining the
151+
appropriateness of using or redistributing the Work and assume any
152+
risks associated with Your exercise of permissions under this License.
153+
154+
8. Limitation of Liability. In no event and under no legal theory,
155+
whether in tort (including negligence), contract, or otherwise,
156+
unless required by applicable law (such as deliberate and grossly
157+
negligent acts) or agreed to in writing, shall any Contributor be
158+
liable to You for damages, including any direct, indirect, special,
159+
incidental, or consequential damages of any character arising as a
160+
result of this License or out of the use or inability to use the
161+
Work (including but not limited to damages for loss of goodwill,
162+
work stoppage, computer failure or malfunction, or any and all
163+
other commercial damages or losses), even if such Contributor
164+
has been advised of the possibility of such damages.
165+
166+
9. Accepting Warranty or Additional Liability. While redistributing
167+
the Work or Derivative Works thereof, You may choose to offer,
168+
and charge a fee for, acceptance of support, warranty, indemnity,
169+
or other liability obligations and/or rights consistent with this
170+
License. However, in accepting such obligations, You may act only
171+
on Your own behalf and on Your sole responsibility, not on behalf
172+
of any other Contributor, and only if You agree to indemnify,
173+
defend, and hold each Contributor harmless for any liability
174+
incurred by, or claims asserted against, such Contributor by reason
175+
of your accepting any such warranty or additional liability.
