Write metadata to image files as MarkdownReports does #4

Closed vertesy closed 1 year ago

vertesy commented 3 years ago
  1. MarkdownReports saves the creating script's name (scriptname) and potentially the author to the title field of the output .pdf files. It was not the case when saving as .png.
  2. I want to implement this is the ggplot based ggExpressDev

Resources

In MarkdownReports:

See title inside ww.dev.copy

 dev.copy2pdf(
      file = ww.FnP_parser(fname_, "pdf"),
      width = w_,
      height = h_,
      title = ww.ttl_field(fname_)

Great! You can pass on title to save_plot and its safely ignored when saving as png.

xx <- qplot(1)
save_plot(filename = "hello.pdf", plot = xx, title="Metadata")

save_plot(filename = "hello.png", plot = xx, title="Metadata")

This is not actually implemented.

  1. qqSave → save_plot → cowplot::ggsave2 can handle it

  2. we need to call ww.ttl_field("/Users/myplot.jpg")

ww.ttl_field("/Users/myplot.jpg")

Solved now
