Copy every figure to JPEG and TIFF — export_figure

knitr writes one format per render, PNG, into figures/png/. This converts each of them into figures/jpg/ and figures/tiff/, at the resolution they were drawn at – the dpi of _quarto.yml, 600 in a new project – and with the TIFF compressed losslessly (LZW), which is what journals ask for on acceptance. Converting is faster than rendering three times, and guarantees the three copies are the same figure. Every render does it on its own.

Usage

export_figure_formats(quiet = FALSE, path = NULL)

Arguments

quiet: TRUE says nothing.
path: The project, or any folder inside it. Left out, the one set_paper() named; with none named, this stops before writing: it writes into the project, and easypaper never takes the working directory for it.

Value

The PNG files converted, invisibly.

Details

JPEG is lossy and a poor choice for line art or figures with text. It is here because some journals require it; if you get to choose, send the TIFF.

Examples

dir <- file.path(tempdir(), "my_paper")
create_paper(dir, git = FALSE)
#> Project created: /tmp/Rtmp92gqjt/my_paper
#>   1. open my_paper.Rproj
#>   2. library(easypaper)
#>   3. set_paper(".")      # the project to work on, once a session
#>   4. render_html()      # see ?render for every command
dir.create(file.path(dir, "figures", "png"), recursive = TRUE)
grDevices::png(file.path(dir, "figures", "png", "fig-a-1.png"))
plot(1:10)
invisible(grDevices::dev.off())
export_figure_formats(path = dir)
#> Figures: 1 x png/jpg/tiff in figures/
list.files(file.path(dir, "figures"), recursive = TRUE)
#> [1] "jpg/fig-a-1.jpg"   "png/fig-a-1.png"   "tiff/fig-a-1.tiff"
unlink(dir, recursive = TRUE)
