1. Provides an unified and simple FFT/IFFT interface. Users no longer need to worry about their FFT results being affected by other programs. All FFT tables are allocated and released within the function scope.
2. Reimplements an int16 FFT/IFFT. Dynamic quantization is used during butterfly operations to achieve better precision.

* Wrapper that protects dl_rfft_post_proc_sc16_asm from int16 overflow.

* The underlying _asm/_ansi implementations compute (sum_r + tw_r) >> 1 in
* 16-bit precision (the SIMD AMS hardware truncates the sum to 16 bits before
* the built-in `>> 1` store, dropping bit 16). When the input data uses the
* full int16 range (e.g. high-precision FFT output), |sum_r + tw_r| can exceed
* 32767 and the truncation produces a result that is 32768 off from the
* mathematically correct value.
*
* To avoid this, we pre-shift the data right by 1 whenever the abs-max
* indicates the data is in int16 range, so all intermediate (sum_r + tw_r)
* values stay within int16. The caller must compensate by adding the returned
* shift to the output exponent.

## Usage
Please refer to the `test_app` folder for more details on API usage.
- `test_app/main/test_encoder.c` for encoder
- Encode a single picture
- Encode a single picture with block encoder API
- `test_app/main/test_decoder.c` for decoder
- Decode a single JPEG picture
- Decode a single JPEG picture with block deocder API
- Decode JPEG stream of the same size
For more information, please refer to [Introducing ESP_NEW_JPEG: An Efficient JPEG Encoder and Decoder](https://developer.espressif.com/blog/2025/09/esp-new-jpeg-introduction/). The article provides detailed information on the features and configuration options of esp_new_jpeg.
## FAQ
1. Does ESP_NEW_JPEG support decoding progressive JPEG?
No, ESP_NEW_JPEG only support decoding baseline JPEG.
You can use the following code to check if the image is progressive JPEG. Output 1 means progressive JPEG, 0 means baseline JPEG.
```bash
python
>>> from PIL import Image
>>> Image.open("file_name.jpg").info.get('progressive', 0)
```
2. Why does the output image appear misaligned?
The issue typically occurs when a few columns of the image on the far left or right side appear on the opposite side. If you are using the ESP32-S3, a possible cause is that the output buffer of decoder or the input buffer of encoder is not 16-byte aligned. Please use the `jpeg_calloc_align` function to allocate buffer.
3. How can I use a simpler method to check if the encoder's output is correct?
You can use the following code to directly print the output JPEG data. Copy the output data, paste it into a hex editor, and save it as a .jpg file.
```c
for (int i = 0; i < out_len; i++) {
printf("%02x", outbuf[i]);
}
printf("\n");
```

FREETYPE LICENSES
-----------------
The FreeType 2 font engine is copyrighted work and cannot be used
legally without a software license. In order to make this project
usable to a vast majority of developers, we distribute it under two
mutually exclusive open-source licenses.
This means that *you* must choose *one* of the two licenses described
below, then obey all its terms and conditions when using FreeType 2 in
any of your projects or products.
- The FreeType License, found in the file `docs/FTL.TXT`, which is
similar to the original BSD license *with* an advertising clause
that forces you to explicitly cite the FreeType project in your
product's documentation. All details are in the license file.
This license is suited to products which don't use the GNU General
Public License.
Note that this license is compatible to the GNU General Public
License version 3, but not version 2.
- The GNU General Public License version 2, found in
`docs/GPLv2.TXT` (any later version can be used also), for
programs which already use the GPL. Note that the FTL is
incompatible with GPLv2 due to its advertisement clause.
The contributed BDF and PCF drivers come with a license similar to
that of the X Window System. It is compatible to the above two
licenses (see files `src/bdf/README` and `src/pcf/README`). The same
holds for the source code files `src/base/fthash.c` and
`include/freetype/internal/fthash.h`; they were part of the BDF driver
in earlier FreeType versions.
The gzip module uses the zlib license (see `src/gzip/zlib.h`) which
too is compatible to the above two licenses.
The files `src/autofit/ft-hb.c` and `src/autofit/ft-hb.h` contain code
taken almost verbatim from the HarfBuzz file `hb-ft.cc`, which uses
the 'Old MIT' license, compatible to the above two licenses.
The MD5 checksum support (only used for debugging in development
builds) is in the public domain.

# FreeType Example
This is a simple example of initializing FreeType library, loading a font from a filesystem, and rendering a line of text.
The font file (DejaVu Sans) is downloaded at compile time and is added into a SPIFFS filesystem image. The filesystem is flashed to the board together with the application. The example loads the font file and renders "FreeType" text into the console as ASCII art.
This example doesn't require any special hardware and can run on any development board.
## Building and running
Run the application as usual for an ESP-IDF project. For example, for ESP32:
```
idf.py set-target esp32
idf.py -p PORT flash monitor
```
## Example output
The example should output the following:
```
I (468) main_task: Calling app_main()
I (538) example: FreeType library initialized
I (1258) example: Font loaded
I (1268) example: Rendering char: 'F'
I (1388) example: Rendering char: 'r'
I (1528) example: Rendering char: 'e'
I (1658) example: Rendering char: 'e'
I (1798) example: Rendering char: 'T'
I (1938) example: Rendering char: 'y'
I (2078) example: Rendering char: 'p'
I (2208) example: Rendering char: 'e'

#
# The following will (1) create a build directory, and (2) change into it and
# call cmake to configure the build with default parameters as a static
# library. See
#
# https://cmake.org/cmake/help/latest/variable/CMAKE_BUILD_TYPE.html
#
# for information about debug or release builds, for example
#
# cmake -B build -D CMAKE_BUILD_TYPE=Release
#
#
# For a dynamic library, use
#
# cmake -B build -D BUILD_SHARED_LIBS=true -D CMAKE_BUILD_TYPE=Release
#
# For a framework on OS X, use
#
# cmake -E chdir build cmake -G Xcode -D BUILD_FRAMEWORK:BOOL=true ..
#
# For an iOS static library, use
#
# cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=OS ..
#
# or
#
# cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR ..
#
# or
#
# cmake -E chdir build cmake -G Xcode -D IOS_PLATFORM=SIMULATOR64 ..
#
#
# Finally, build the project with
#
# cmake --build build
#
# Install it with
#
# (sudo) cmake --build build --target install
#
# A binary distribution can be made with
#
# cmake --build build --config Release --target package
#
# Please refer to the cmake manual for further options, in particular, how
# to modify compilation and linking parameters.
#
# Some notes.
#
# - Say `cmake -LAH` to see all configuration options.
#
# - `cmake' creates configuration files in
#
# <build-directory>/include/freetype/config
#
# which should be further modified if necessary.
#
# - You can use `cmake' directly on a freshly cloned FreeType git
# repository.
#
# - `CMakeLists.txt' is provided as-is since it is normally not used by the
# developer team.
#
# - Set the `FT_REQUIRE_ZLIB', `FT_REQUIRE_BZIP2', `FT_REQUIRE_PNG',
# `FT_REQUIRE_HARFBUZZ', and `FT_REQUIRE_BROTLI' CMake variables to `ON'
# or `TRUE' to force using a dependency. Leave a variable undefined
# (which is the default) to use the dependency only if it is available.
# Example:
#
# cmake -B build -D FT_REQUIRE_ZLIB=TRUE \
# -D FT_REQUIRE_BZIP2=TRUE \
# -D FT_REQUIRE_PNG=TRUE \
# -D FT_REQUIRE_HARFBUZZ=TRUE \
# -D FT_REQUIRE_BROTLI=TRUE [...]
#
# - Set the `FT_DYNAMIC_HARFBUZZ' CMake variable to `ON' or `TRUE' to load
# the HarfBuzz library dynamically at runtime, if possible. Example:
#
# cmake -B build -D FT_DYNAMIC_HARFBUZZ=TRUE [...]
#
# - Set `FT_DISABLE_XXX=TRUE' to disable a dependency completely (where
# `XXX' is a CMake package name like `BZip2'). Example for disabling all
# dependencies:
#
# cmake -B build -D FT_DISABLE_ZLIB=TRUE \
# -D FT_DISABLE_BZIP2=TRUE \
# -D FT_DISABLE_PNG=TRUE \
# -D FT_DISABLE_HARFBUZZ=TRUE \
# -D FT_DISABLE_BROTLI=TRUE [...]
#
# - NOTE: If a package is set as DISABLED, it cannot be set as REQUIRED
# without unsetting the DISABLED value first. For example, if
# `FT_DISABLE_HARFBUZZ=TRUE' has been set (Cache is present), you need to
# call `FT_DISABLE_HARFBUZZ=FALSE' before calling
# `FT_REQUIRE_HARFBUZZ=TRUE'.
#
# - Installation of FreeType can be controlled with the CMake variables
# `SKIP_INSTALL_HEADERS', `SKIP_INSTALL_LIBRARIES', and `SKIP_INSTALL_ALL'
# (this is compatible with the same CMake variables in zlib's CMake
# support).
# CMake 3.12 provides for IMPORTED targets for common libraries like zlib, libpng and bzip2

FREETYPE LICENSES
-----------------
The FreeType 2 font engine is copyrighted work and cannot be used
legally without a software license. In order to make this project
usable to a vast majority of developers, we distribute it under two
mutually exclusive open-source licenses.
This means that *you* must choose *one* of the two licenses described
below, then obey all its terms and conditions when using FreeType 2 in
any of your projects or products.
- The FreeType License, found in the file `docs/FTL.TXT`, which is
similar to the original BSD license *with* an advertising clause
that forces you to explicitly cite the FreeType project in your
product's documentation. All details are in the license file.
This license is suited to products which don't use the GNU General
Public License.
Note that this license is compatible to the GNU General Public
License version 3, but not version 2.
- The GNU General Public License version 2, found in
`docs/GPLv2.TXT` (any later version can be used also), for
programs which already use the GPL. Note that the FTL is
incompatible with GPLv2 due to its advertisement clause.
The contributed BDF and PCF drivers come with a license similar to
that of the X Window System. It is compatible to the above two
licenses (see files `src/bdf/README` and `src/pcf/README`). The same
holds for the source code files `src/base/fthash.c` and
`include/freetype/internal/fthash.h`; they were part of the BDF driver
in earlier FreeType versions.
The gzip module uses the zlib license (see `src/gzip/zlib.h`) which
too is compatible to the above two licenses.
The files `src/autofit/ft-hb-ft.c`, `src/autofit/ft-hb-decls.h`,
`src/autofit/ft-hb-types.h`, and `src/autofit/hb-script-list.h`
contain code taken (almost) verbatim from the HarfBuzz library, which
uses the 'Old MIT' license compatible to the above two licenses.
The MD5 checksum support (only used for debugging in development
builds) is in the public domain.

FreeType 2.14.2
===============
Homepage: https://freetype.org
FreeType is a freely available software library to render fonts.
It is written in C, designed to be small, efficient, highly
customizable, and portable while capable of producing high-quality
output (glyph images) of most vector and bitmap font formats.
Please read the `docs/CHANGES` file, it contains IMPORTANT
INFORMATION.
Read the files `docs/INSTALL*` for installation instructions; see the
file `LICENSE.TXT` for the available licenses.
For using FreeType's git repository instead of a distribution bundle,
please read file `README.git`. Note that you have to actually clone
the repository; using a snapshot will not work (in other words, don't
use gitlab's 'Download' button).
The FreeType 2 API reference is located in directory `docs/reference`;
use the file `index.html` as the top entry point. [Please note that
currently the search function for locally installed documentation
doesn't work due to cross-site scripting issues.]
Additional documentation is available as a separate package from our
sites. Go to
https://download.savannah.gnu.org/releases/freetype/
and download one of the following files.
freetype-doc-2.14.2.tar.xz
freetype-doc-2.14.2.tar.gz
ftdoc2142.zip
To view the documentation online, go to
https://freetype.org/freetype2/docs/
Mailing Lists
-------------
The preferred way of communication with the FreeType team is using
e-mail lists.
general use and discussion: freetype@nongnu.org
engine internals, porting, etc.: freetype-devel@nongnu.org
announcements: freetype-announce@nongnu.org
git repository tracker: freetype-commit@nongnu.org
The lists are moderated; see
https://freetype.org/contact.html
how to subscribe.
Bugs
----
Please submit bug reports at
https://gitlab.freedesktop.org/freetype/freetype/-/issues
Alternatively, you might report bugs by e-mail to
`freetype-devel@nongnu.org`. Don't forget to send a detailed
explanation of the problem -- there is nothing worse than receiving a
terse message that only says 'it doesn't work'.
Patches
-------
For larger changes please provide merge requests at
https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests
Alternatively, you can send patches to the `freetype-devel@nongnu.org`
mailing list -- and thank you in advance for your work on improving
FreeType!
Details on the process can be found here:
https://freetype.org/developer.html#patches
Enjoy!

repository issues
-----------------
FreeType's official repository site is
https://gitlab.freedesktop.org/freetype ,
from which the 'freetype.git' and 'freetype-demos.git' repositories
can be cloned in the usual way.
git clone https://gitlab.freedesktop.org/freetype/freetype.git
git clone https://gitlab.freedesktop.org/freetype/freetype-demos.git
If you want to use the Savannah mirror instead, you have to do a
slightly different incantation because the repository names contain
digit '2' for historical reasons.
git clone \
https://git.savannah.nongnu.org/git/freetype/freetype2.git \
freetype
git clone \
https://git.savannah.nongnu.org/git/freetype/freetype2-demos.git \
freetype-demos
standard builds with `configure`
--------------------------------
The git repository doesn't contain pre-built configuration scripts for
UNIXish platforms. To generate them say
sh autogen.sh
which in turn depends on the following packages:
automake (1.10.1)
libtool (2.2.4)
autoconf (2.62)
The versions given in parentheses are known to work. Newer versions
should work too, of course. Note that `autogen.sh` also sets up
proper file permissions for the `configure` and auxiliary scripts.
The `autogen.sh` script checks whether the versions of the above three
tools match the numbers above. Otherwise it will complain and suggest
either upgrading or using environment variables to point to more
recent versions of the required tools.
Note that `aclocal` is provided by the 'automake' package on Linux,
and that `libtoolize` is called `glibtoolize` on Darwin (OS X).
alternative build methods
-------------------------
For static builds that don't use platform-specific optimizations, no
configure script is necessary at all; saying
make setup ansi
make
should work on all platforms that have GNU `make` (or `makepp`).
A build with `cmake` or `meson` can be done directly from the git
repository. However, if you want to use the `FT_DEBUG_LOGGING` macro
(see file `docs/DEBUG` for more information) it is currently mandatory
to execute `autogen.sh` in advance; this script clones the 'dlg' git
submodule and copies some files into FreeType's source tree.

The makefile.os4 is for the AmigaOS4 SDK. To use it, type
"make -f makefile.os4", it produces a link library libft2_ppc.a.
The makefile is for ppc-morphos-gcc-2.95.3-bin.tgz (gcc 2.95.3 hosted on
68k-Amiga producing MorphOS-PPC-binaries from http://www.morphos.de).
To use it, type "make assign", then "make"; it produces a link library
libft2_ppc.a.
The smakefile is a makefile for Amiga SAS/C 6.58 (no longer available,
latest sold version was 6.50, updates can be found in Aminet). It is
based on the version found in the sourcecode of ttf.library 0.83b for
FreeType 1.3.1 from Richard Griffith (ragriffi@sprynet.com,
http://ragriffi.home.sprynet.com).
You will also need the latest include files and amiga.lib from the
Amiga web site (https://os.amigaworld.de/download.php?id=3) for
AmigaOS 3.9; the generated code should work under AmigaOS 2.04 and up.
To use it, call "smake assign" and then "smake" from the builds/amiga
directory. The results are:
- A link library "ft2_680x0.lib" (where x depends on the setting of
the CPU entry in the smakefile) containing all FreeType2 parts
except of the init code, debugging code, and the system interface
code.
- ftsystem.o, an object module containing the standard version of the
system interface code which uses fopen() fclose() fread() fseek()
ftell() malloc() realloc() and free() from lib:sc.lib (not pure).
- ftsystempure.o, an object module containing the pure version of the
system interface code which uses Open() Close() Read() Seek()
ExamineFH() AsmAllocPooled() AsmFreePooled() etc. This version can
be used in both normal programs and in Amiga run-time shared system
librarys (can be linked with lib:libinit.o, no copying of DATA and
BSS hunks for each OpenLibrary() necessary). Source code is in
src/base/ftsystem.c.
- ftdebug.o, an object module containing the standard version of the
debugging code which uses vprintf() and exit() (not pure).
Debugging can be turned on in FT:include/freetype/config/ftoption.h
and with FT_SetTraceLevel().
- ftdebugpure.o, an object module containing the pure version of the
debugging code which uses KVPrintf() from lib:debug.lib and no
exit(). For debugging of Amiga run-time shared system libraries.
Source code is in src/base/ftdebug.c.
- NO ftinit.o. Because linking with a link library should result in
linking only the needed object modules in it, but standard
ftsystem.o would force ALL FreeType2 modules to be linked to your
program, I decided to use a different scheme: You must #include
FT:src/base/ftinit.c in your sourcecode and specify with #define
statements which modules you need. See
include/freetype/config/ftmodule.h.
To use in your own programs:
- Insert the #define and #include statements from top of
include/freetype/config/ftmodule.h in your source code and
uncomment the #define statements for the FreeType2 modules you need.
- You can use either PARAMETERS=REGISTER or PARAMETERS=STACK for
calling the FreeType2 functions, because the link library and the
object files are compiled with PARAMETERS=BOTH.
- "smake assign" (assign "FT:" to the FreeType2 main directory).
- Compile your program.
- Link with either ftsystem.o or ftsystempure.o, if debugging enabled
with either ftdebug.o or (ftdebugpure.o and lib:debug.lib), and with
ft2_680x0.lib as link library.
To adapt to other compilers:
- The standard ANSI C maximum length of 31 significant characters in
identifiers is not enough for FreeType2. Check if your compiler has
a minimum length of 40 significant characters or can be switched to
it. "idlen=40" is the option for SAS/C. Setting #define
HAVE_LIMIT_ON_IDENTS in an include file may also work (not tested).
- Make sure that the include directory in builds/amiga is searched
before the normal FreeType2 include directory, so you are able to
replace problematic include files with your own version (same may be
useful for the src directory).
- An example of how to replace/workaround a problematic include file
is include/freetype/config/ftconfig.h; it changes a #define that
would prevent SAS/C from generating XDEF's where it should do that and
then includes the standard FreeType2 include file.

Compiling FreeType 2 with PureC compiler
========================================
[See below for a German version.]
To compile FreeType 2 as a library the following changes must be applied:
- All *.c files must start with an uppercase letter.
(In case GEMSCRIPT is available:
Simply drag the whole FreeType 2 directory to the file `FNames.SIC'.)
- You have to change the INCLUDE directory in PureC's compiler options
to contain both the `INCLUDE' and `freetype2\include' directory.
Example:
INCLUDE;E:\freetype2\include
- The file `freetype/include/Ft2build.h' must be patched as follows to
include ATARI.H:
#ifndef FT2_BUILD_GENERIC_H_
#define FT2_BUILD_GENERIC_H_
#include "ATARI.H"
Compilieren von FreeType 2 mit PureC
====================================
Um FreeType 2 als eine Bibliothek (library) zu compilieren, muss folgendes
ge„ndert werden:
- Alle *.c-files m<>ssen mit einem GROSSBUCHSTABEN beginnen.
(Falls GEMSCRIPT zur Verf<72>gung steht:
Den kompletten Ordner freetype2 auf die Datei `FNames.SIC' draggen.)
- In den Compiler-Optionen von PureC muss das INCLUDE directory auf INCLUDE
und freetype2\include verweisen. Z.B.:
INCLUDE;E:\freetype2\include
- In der Datei freetype/include/Ft2build.h muss zu Beginn
ein #include "ATARI.H" wie folgt eingef<65>gt werden:
#ifndef FT2_BUILD_GENERIC_H_
#define FT2_BUILD_GENERIC_H_
#include "ATARI.H"
