Windows 64-bit jpegoptim builds

jpegoptim for Windows

This is just my own project files for easy building of jpegoptim with mozjpeg and Microsoft Visual Studio. Currently only 64-bit (x64) is targeted.

Notes

• Multithreaded; no need for the MSVC Runtime to be installed separately
• Built with LTCG
• Runs on Windows Vista and newer

Build Instructions

1. Clone the repository

   git clone --recursive https://github.com/XhmikosR/jpegoptim-windows.git

   Alternatively you can do this:

   git submodule init
   git submodule update --recursive

2. Download and install Visual Studio 2022 (any edition)

3. Download nasm and place nasm.exe somewhere into your PATH

4. Open jpegoptim.sln and build, or run build.bat

Sample scripts

WARNING: The following scripts optimize the images in place! Remember to make a backup before running them.

Here's a sample script that loops through only the first-level subfolders in a folder optimizing all pictures:

for /f "tokens=*" %%i in ('dir /a:d /b') do (
  jpegoptim.exe --preserve --strip-all --totals --verbose "%%i\*.jpg"
)

Here's another sample script that loops through all subfolders in a folder optimizing all pictures:

for /f "delims=" %%i in ('dir /b /s *.jpg') do (
  jpegoptim.exe --preserve --strip-all --verbose "%%i"
)

jpegoptim-windows's Issues

Parallel processing support in 1.5.1?

Should this parallel processing work? Even no mention in help output --help

AFAIK this -w option works since version 1.5.0.
>>Parallel processing support added. Use option -w max or --workers=max to enable.

I built Timo's jpegoptim under Ubuntu and the -w worked just fine
This Windows build seems to have no this option enabled
I am correct?

I really need this parallel processing under Windows... Is there a way to get it?

Thank you

Automate release creation

Enable experimental --with-arith

According to 1.4.7 changelog --with-arith experimental option is available if compiled with support to it.
Can you please build it with such option?

Simple installer / portable Windows 10 app for newbies?

Hi,

This will help newbies like me to use this application.

Thanks a lot!

Error if path to solution contains whitespaces

Hi just want to mention that the build breaks if the path where the solution is at contains white spaces:

e.g. C:\Users\Name Name\...

It gives a multiple input files error when trying to run NASM.

in src\nasm.targets: line 52:

OutputFormat="%(NASM.OutputFormat)" needs to be changed to
OutputFormat=""%(NASM.OutputFormat)""

Update mozjpeg to v4.x

Switch to GitHub Actions CI

Add AppVeyor

Multithreaded support

Version 1.5.0 of jpegoptim added the --workers flag to set parallel workers to process all the images. Would it be possible to add this option to the Windows version?

Select all files in folder / asterisk select is not possible

d:\TEMP\>jpegoptim.exe *.jpg
jpegoptim: skipping special file: *.jpg

d:\TEMP\>jpegoptim2.exe ./
jpegoptim: skipping directory: ./

In version 1.4.4 it was possible optimize *.jpg with no problem.
