The programs in this repository convert data found in the clipboard to a Data URL, then copy the URL's text back to the clipboard. The data can be a file, RGB image data or text. RGB image data will be converted to represent a PNG file before being converted to a Data URL.
Data URLs are useful to embed images e.g. in HTML or Markdown documents.
sudo apt update
sudo apt install libspng-dev
git clone https://github.com/607011/clip2png2clip.git
cd clip2png2clip
git submodule init
git submodule update --remote --merge
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .
brew update
brew install cmake libspng zlib
git clone https://github.com/607011/clip2png2clip.git
cd clip2png2clip
git submodule init
git submodule update --remote --merge
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
cmake --build .
If not already present, install Git and Git bash:
winget install --id Git.Git -e --source winget
Launch Visual Studio Developer Command Prompt. Then:
git clone https://github.com/607011/clip2png2clip.git
cd clip2png2clip
git submodule init
git submodule update --remote --merge
cd 3rdparty/zlib-1.2.13
cmake .
cmake --build . --config Release
cp Release/zlib.lib .
cd ../..
cmake . -DZLIB_ROOT="3rdparty/zlib-1.2.13"
cmake --build . --config Release
You'll find the compiled binaries in the subdirectory "Release".
To execute they need some DLLs shipped with the Microsoft compiler:
- api-ms-win-crt-heap-l1-1-0.dll
- api-ms-win-crt-math-l1-1-0.dll
- api-ms-win-crt-stdio-l1-1-0.dll
- api-ms-win-crt-locale-l1-1-0.dll
- api-ms-win-crt-runtime-l1-1-0.dll
On Windows 11 using Visual Studio Community Edition you'll find them in %PROGRAMFILES%/Microsoft Visual Studio/2022/Community/Common7/Tools
Copy the DLLs from there to "Release".
Do the same with 3rdparty/libspng/Release/spng.dll and 3rdparty/zlib-1.2.13/Release/zlib.dll.
Now Release/clip2dataurl will run properly.
Convert clipboard contents to Data URL and copy it to the clipboard:
./clip2dataurl
Same as above but write Data URL to stdout:
./clip2stdout
