Breaking API changes for 1.0.0
This issue is for listing potentially breaking API changes for 1.0.0.
The API is guaranteed to be stable starting from 0.4.0 through 0.8.x and is tracked on ABI laboratory, note that it detects changes to the opaque type spng_ctx as breaks and needs manual verification.
So far no major mistakes have been made to warrant an incompatible API for 1.0.0
Streaming API improvements
The streaming API is similar to libpng's which is great when it comes porting code but it has some drawbacks, this issue is for listing potential improvements.
Simplified API
This issue tracks nice-to-have functions that can be implemented on top of existing functionality.
Decode from file
Similar to stbi_load()
int spng_decode_file(const char *filename, void **buf, struct spng_ihdr *ihdr, int fmt, int flags);Depends on #47
This does not allow for a custom memory allocator nor context flags, which is a drawback.
New image format - PNG / RAW
PNG
SPNG_FMT_PNG would match the context's PNG image format in host-endian, 16-bit RGBA/GRAY images are converted to host endianness when decoding, indexed color images are unmodified palette indices, even if they're 1/2/4-bit, the same applies for >8-bit grayscale images.
Indexed color images could be handled multiple ways:
- output the palette indices, TRNS, GAMMA could be applied to a user-supplied palette
Other options which would break the simplicity of calculating the output image size based on just the format and dimensions:
2. expand to 8-bit RGB, only GAMMA has an effect and the transparency value becomes useless
3. default to palette indices, add a separate function to override the format
4. expand to 8-bit RGB, gamma correction would work and the TRNS flag would expand it to RGBA, this changes the output format with a flag and would only expand to 8-bit
Gamma correction (SPNG_DECODE_GAMMA) is supported with this format.
RAW
SPNG_FMT_RAW is the big-endian version of SPNG_FMT_PNG.
Gamma correction is not supported with this format.
Progress:
-
SPNG_FMT_RAW -
SPNG_FMT_PNG
Read only the IHDR chunk in spng_get_ihdr()
Currently all data up to the first IDAT chunk is read in spng_get_ihdr().
depends on #38
Tests error on s390x: invalid gamma correction
Some tests issues specifically happening on s390x:

Some gamma-corrected images don't match libpng's output
basi0g16, basn0g16, oi1n0g16, oi2n0g16, oi4n0g16, oi9n0g16 tests fail with the same error message:
Decode and compare RGBA8, FLAGS: USE_TRNS USE_GAMA invalid gamma correction at x: 31 y:31, spng: 0 0 0 png: 19 19 19
Without gamma correction both pixels at 0,0 and 31,31 are decoded to rgb 0 0 0 for both libraries.
On libpng's gamma-corrected output the pixel at 0,0 is rgb 0 0 0 but at 31,31 it's rgb 19 19 19.
Background color composition (bKGD)
Unindexing indexed pngs
There is no example for unindexing images, is there a preimplemented function I didn't see?
I found that to obtain the color map I should do:
struct spng_plte color_map;
spng_get_plte(ctx, &color_map);
But how do I know the size of each channel and the amount of channels? There is such info in spng_plte.
Unknown chunk support

Functions for configuring filtering/compression is tracked by #25.
Decoding callbacks (info/chunk/row)
This feature may be limited to only work with push mode decoding, this should be implemented with APNG support (frame callbacks?) in mind.
Row callbacks would be issued when there is enough data to decode the image and spng_decode_scanline() / spng_decode_row() would have to be called inside the callback.
Apple CgBI write support
Depends on #16
Text / color profile chunk read support
Text and color profile chunks contain compressed data, support for these chunks was removed because it was vulnerable to decompression bombs. With the introduction of chunk size and cache limits in v0.5.0 this could be solved two ways:
-
Store chunk data as-is, decompress and validate on
spng_get_*(), the chunk cache or some other limit would still apply, this uses more memory. -
Decompress the data progressively with a small buffer and discard the chunk if decompression would exceed the cache limit, this would bypass the chunk size limit
Depends partially on #10
Some images fail to decode
All images from libpng/contrib/testpngs (excluding the the crashers directory) fail to decode with SPNG_EZLIB as error. zlib returns Z_DATA_ERROR.
APNG inter-frame optimization

Fails to access an indexed color image palette read from disk
The function used to access an indexed color image's palette spng_get_plte seems to not be functional when trying to access a non-user provided color palette. I modified the code in examples/example.c to print out a few levels of the palette when an indexed color image is loaded and it will always return ERR #73 - chunk not available.
I believe this occurs because when the color palette is read only ctx->file.plte = 1 is set, whereas for most chunks processed in read_chunks_before_idat it appears that ctx->stored.plte = 1 gets set as well.
My chosen test image was: tests/images/basn3p08.png
Testing code added to examples/example.c (~around line 100)
if(ihdr.color_type == SPNG_COLOR_TYPE_INDEXED) {
struct spng_plte color_map;
r = spng_get_plte(ctx, &color_map);
if(r) {
printf("ERR #%d - %s\n", r, spng_strerror(r));
goto err;
}
printf("%hhu %hhu %hhu\n", color_map.entries[0].red,
color_map.entries[0].green,

libspng should be able to edit/reencode PNG's in a standard conformant way: #99
There are at least two ways to implement this:
- Define context types: decoder, encoder and editor, a single context can only serve one of three functions, this determined by the source type (input png,
spng_ctxor none for plain encoders), in this case: - Calling
spng_set_*()will be an error for decoders - Encoders will not be able to encode from a PNG, only from image buffers in a
SPNG_FMT_*format - Editor contexts would require a "source context" that is configured for decoding, add a new function e.g.
spng_set_src_ctx(). - Currently the
spng_set_*()functions discard existing chunk data for that type, this behavior would be limited to editor contexts
- Provide editor support within the same context, this was the initial plan but now it seems unnecessarily complicated, the semantics of
spng_get/set_*()was created with this in mind but it's a usability nightmare and could also lead to security vulnerablities.
Testsuite improvements
Increase code coverage:
- All
_getfunctions should be tested - All
_setfunctions should be tested - Compare standard chunk values against
libpng - Add more valid test files with: iCCP, sRGB, oFFs chunks
- Add more invalid test files: zero-length PLTE
- Test
set_image_limits()
Error handling
There have been issues with error handling which lead to some tests to silently pass, outputting a TAP stream would mitigate this, Meson is a TAP consumer so this shouldn't require too much effort.
- Write a TAP stream
- Switch the unit tests' protocol to TAP
libpng dependency
Once encode support is done round-trip encode->decode->compare tests will make the libpng dependency unnecessary in most cases.
- Tests should be available without the
-Ddev_buildoption, it would still control comparison tests against libpng
ARM NEON palette optimizations
Adapt libpng's NEON palette optimizations
Command-line tool
Initially it would just print machine-readable information about PNGs:

Potential names: spnginfo, spngutil, spngtool or just spng
Improve CI
Currently CI is done on the original repo and appveyor.
-
Migrate from GitLab CI to Actions/Travis (gcc, clang, scan-build, tests with ASan/UBsan, coverage build, codecov trigger and Coverity Scan)Not needed, GitLab can run on PRs now. -

Decode without alpha?
Thank you for all your hard work in making libspng!
Do you have any plans to support decoding without the alpha channel?
Reading in streaming mode can result in chunks not loading properly
read_idat_bytes is used to read data chunk bytes. However, when used in streaming mode, the amount of data to read can be incorrect, which results in an error being returned by read_chunk_bytes when attempting to read data from the chunk, which in turns results in an error being returned during the spng_decode_image call.
Changing the line
if(len > ctx->current_chunk.length) len = ctx->current_chunk.length;
to
if(len > ctx->cur_chunk_bytes_left) len = ctx->cur_chunk_bytes_left;
in read_idat_bytes fixes the issue.
This was observed on v0.5.0
Zero-copy decoding
Zero-copy decoding consists of decompressing scanlines directly to the output buffer, this would be limited to non-interlaced images with the following PNG format -> output format combinations:
- RGBA8->RGBA8
- RGBA16->RGBA16
- PNG -> PNG (#24)
GA16 -> RGBA8 with some tweaks
| Format | Bytes per pixel |
|---|---|
| Indexed/Gray 1/2/4bit | 1 |
| Gray 8-bit | 1 |
| Gray 16-bit | 2 |
| Gray alpha 8-bit | 2 |
| Gray alpha 16-bit | 4 |
| RGB 8-bit | 3 |
| RGB 16-bit | 6 |
| RGBA 8-bit | 4 |
| RGBA 16-bit | 8 |
This may reduce performance (or not work, depending on optimizations and platform) because the scanlines are not always aligned.
Apple CgBI read support
CgBI is Apple's proprietary, incompatible extension to the PNG format.
relevant links:
Standard conformance vs libpng compatibility
This is a meta-issue is for all libpng compatibility issues caused by strict conformance checks.
libspng is very strict with parsing PNG's, almost any deviation from the standard results in an error. This can cause issues because libpng's implementation is the de facto PNG standard which is a lot more loose with checks, it will issue warnings/skip invalid chunks as long as the image can be decoded.
libspng should be able to decode PNG's that aren't standard conformant but are decoded by libpng in most cases, this should be the default behavior with an option to reenable these checks if there is demand for it.
Animated PNG (APNG) read support
APNG is an unofficial extension by Mozilla, it allows for animated PNG files that work similarly to animated GIF files, while supporting 24-bit images and 8-bit transparency not available for GIFs.
- https://wiki.mozilla.org/APNG_Specification
- https://sourceforge.net/projects/apng/
- https://commons.wikimedia.org/wiki/Category:Animated_PNG
This issue depends on #40 (row- and chunk callbacks)
This would be implemented without callbacks, it should be possible to reuse spng_decode_image() for decoding the APNG frames.
Implementation
-
Parse and validate acTL, fcTL chunks
-
Implement frame decoding / fdAT parsing
-
API
Testing
-
Create a libpng-apng repository: https://github.com/randy408/libpng-apng (update to v1.6.39)Went with another approach -
Modify libpng's meson.build to enable APNG support
-
Replace the current libpng Meson wrap
-
Add APNG test images
-
Frame and metadata comparison tests against libpng
Other
-
Update seed corpus
-
Update fuzz target
Documentation

-
Document the new testsuite requirements for distro packagers
-
Update migration guide

Usage example
Multithreaded encoding
There are multiple ways to do this, needs research.
Big endian CI
Multithreaded / pipelined decoding
Decompression can be its own pipeline with the rest of the processing happening on a separate thread, combined with zero-copy decoding(#26) this would only require height bytes of overhead.
Performance issue with some images
Decoding wishes.png is ~3 times slower than libpng:
- www.liimatta.org/misc/images.zip
- https://www.reddit.com/r/programming/comments/fcwhwf/libspng_simple_modern_libpng_alternative/
Will have to find a similar image with a license to use for regression testing.
NEON filter optimizations trigger AddressSanitizer
It triggers it with truecolor 8-bit images.
Implement context states
Inspired by sfpng, this would enable functions (e.g. spng_get_ihdr(), spng_decode_image()) to parse less data before returning.
Push mode decoding
Introduce a feature similar to libpng's push mode (png_process_data()), this could implemented on top of the existing codepaths but will require some refactoring to support incremental decoding.
Depends on #38
Missing check for PLTE for indexed color images
For indexed color images spng_decode_image() does not check if a PLTE chunk is stored, this shouldn't be a security issue but is undesirable behavior.
Uncovered by #42
Add function for retrieving pass dimensions, byte width, etc
- Extend/expose
struct spng_subimages - Add
spng_get_subimages()or something similar
APNG write support
Depends on #4

Usage example
New feature - decode from file
Introduce new functions:
int spng_set_png_file(spng_ctx *ctx, FILE *f); // will not call fclose()
int spng_set_png_path(spng_ctx *ctx, const char *path); // calls fopen(), fclose() on spng_ctx_free()spng_set_png_path() may not be necessary.
Encode filter optimizations - x86
Progressive image read support
The code is already structured to handle row callbacks, this depends on #10, the testsuite also needs some refactoring before tests can be added for this.
Performance
This issue is for discussing performance in general.
spng_get_*() / spng_set_*() semantics
The semantics of spng_get_*() / spng_set_*() get awkward with encode and editor/reencode support, figure out somekind of non-confusing behavior for these.
decode_image(): unset flags that have no effect
e.g. SPNG_DECODE_TRNS for images with an alpha channel, it prevents taking more optimized paths.
