This tool compares the PDF output of Skia's DM tool of two commits.
|
|
|
|
It relies on pdfium_test being in the PATH. To build:
|
|
|
|
mkdir -p ~/src/pdfium
|
|
cd ~/src/pdfium
|
|
gclient config --unmanaged https://pdfium.googlesource.com/pdfium.git
|
|
gclient sync
|
|
cd pdfium
|
|
gn gen out/default --args='pdf_enable_xfa=false pdf_enable_v8=false pdf_is_standalone=true'
|
|
ninja -C out/default pdfium_test
|
|
cp out/default/pdfium_test ~/bin/
