FileIO.jl integration for PNG files
Installation is recommended via the ImageIO thin IO wrapper for FileIO:
pkg> add ImageIO # Press ']' to enter te Pkg REPL mode.Once ImageIO is installed, usage is as simple as:
using FileIO
save("img.png", rand(Gray, 100, 100))
img = load("img.png")Or direct usage, if PNGFiles has been directly installed:
using PNGFiles
PNGFiles.save("img.png", rand(Gray, 100, 100))
img = PNGFiles.load("img.png")

Xref: JuliaIO/ImageIO.jl#41 (comment), @johnnychen94.
For reference, the image used here is a scaled version of toucan.png from TestImages.jl: $ convert toucan.png -scale 5% img.png.
Tested with #47 but still fails on 1.6.5 or 1.7.1 (official binaries):

OK, so this a Srgba vs rgba thing, let's use the SRGB -> linear transformation (https://en.wikipedia.org/wiki/SRGB#Transformation) (sorry i'm not very familiar with images theory, is that correct ?)

I do not have ImageMagick.jl installed, but I do have
. Plots.jl v1.6.6
. FileIO v1.4.3
. ImageIO.jl v0.3.0
. PNGFiles v0.3.1
Without the call pyplot() the example works fine.
In issue JuliaIO/FileIO.jl#275 it was guided to open an issue here.
Here is a MWE. I tried to make it smaller, but it seems like all of these steps are needed:
import Pkg
Pkg.activate(mktempdir())
Pkg.add([
Pkg.PackageSpec(name="Images", version="0.23.3"),
Pkg.PackageSpec(name="ImageIO", version="0.4.1"),
])
using Images
default_iocontext = IOContext(devnull, :color => false, :limit => true, :displaysize => (18, 88))
io() = IOContext(IOBuffer(), default_iocontext)
img = load(download("https://user-images.githubusercontent.com/6933510/107239146-dcc3fd00-6a28-11eb-8c7b-41aaf6618935.png"))
small = img[1:7,1:7]
for i in 1:10000
show(io(), MIME"image/png"(), small)

This breaks IJulia's display of AxisArrays:
Thoughts @IanButterworth @johnnychen94 ?
I just added a benchmark script at https://github.com/JuliaIO/PNG.jl/blob/master/benchmarking/benchmark.jl
Looks like QuartzImageIO >> PNG > ImageMagick overall, but PNG is fastest to load
All of this is before @Drvi's IanButterworth/ImageIODevelopment.jl#3 which looks like it will improve things 👍🏻

I am processing several png files using a Threads.@threads for loop, and was experiencing segfaults inside libpng (see below). The issue was fixed when I Pkg.develop'ed a local copy of PNGFiles where I replaced the lines above with:

Currently, when processing paletted images, we first prepare a palette color buffer of maximum size (PNG_MAX_PALETTE_LENGTH, 256), then we query the file to populate the buffer and finally we resize the buffer to match the number of the color entries in the file. As @t-bltg noted (#47 (comment)), there is a way to know the palette length before populating the buffer, in which case we could simply create the buffer of the correct size.
IIUC, to be able to get the palette length early, one has to use libpng transformation (see the comment referenced above), so we need to figure out how to do it and whether it's beneficial in terms of performance.
Segfaults not on all images, doesn't seem to be related to the PNGFiles version.

I'm not sure where to report this one. Essentially I was hoping to create a PNG from a SparseArray. The MWE follows.
using PNGFiles
using SparseArrays
using ColorSchemes
using ColorVectorSpace # supplies zero(::ColorTypes.RGB{Float64}).
sm = sparse([1,2,3], [4,5,6], [7,8,9])
coloured = get(ColorSchemes.bwr, sm)
PNGFiles.save("sm.png", coloured)Below is the error produced from the example.

I think there is a missing unsafe_convert method for SparseArray?

following all the way from JuliaIO/ImageIO.jl#6 and JuliaImages/Images.jl#912, it turns out #14 isn't so generic...
Tracking down with debugger, here's a minimal example that reproduces the issue:
julia> using Base64, ImageCore, PNGFiles
julia> io = Base64EncodePipe(IOBuffer())
julia> img = rand(RGB{N0f8}, 2, 2)
julia> PNGFiles.save(io, img)The result take!(io.io) is then passed down to VSCode or whatever displayer.
I'm not familiar with libpng and C bindings to fix the issue, but the root problem seems to be
Line 298 in 206430f
Instead of writing to file handle, here we need to write contents to IO buffer via the Base64 encoder pipe s. I don't know how the pointer of s can be passed to libpng, though. Any guidance would be helpful.
Other related PRs:
mapi keywordsiswritable. A patch is still needed here for old Julia versions.maybe_lock for Base64EncodePipe and IOBuffer types.I have a simple server that just serves up a raw PNG file any client that connects. In Julia I wrote the following function to attempt to load that image.
function ReadTeensyImage(server)
sock = Sockets.connect(server,555)
img = load(sock)
close(sock)
return img
endWhen calling the above function, I get the error below. From what I can tell, the library assumes the IO object has a lock function unless it is a specific type that does not. This approach seems problematic for other packages to add IO types that don't support locking.
