function to invoke `pdftools:pdf_convert()`
This function is designed to be used internally and is called by `texor::pdf_to_png(file_dir)` function for converting individual of pdf image.
Note : The extensions in LaTeX source code will automatically be changed during pandoc conversion by a lua filter (refer : inst/extdata/image_filter.lua)
Note
If you find inconsistencies in the raster image generated from PDF using this function. Please update poppler utils to newer versions (possibly latest one).
Examples
article_dir <- system.file("examples/pdf_conversion",
package = "texor")
dir.create(your_article_folder <- file.path(tempdir(), "tempdir"))
x <- file.copy(from = article_dir, to = your_article_folder,recursive = TRUE,)
your_article_path <- paste(your_article_folder,"pdf_conversion",sep="/")
rmarkdown::pandoc_version()
#> [1] ‘3.1.11’
texor::convert_to_png(paste0(your_article_path,"/normal.pdf"))
#> Converting page 1 to /private/var/folders/0g/hj_q_pzx65bbjnslxz9n0src0000gn/T/RtmpUKIyNB/tempdir/pdf_conversion/normal.png... done!
#> [1] "/private/var/folders/0g/hj_q_pzx65bbjnslxz9n0src0000gn/T/RtmpUKIyNB/tempdir/pdf_conversion/normal.png"
