catalog2pdf: Combine 'catalog' images into pdfs

In warbleR: Streamline Bioacoustic Analysis

Combine catalog images into pdfs

Description

catalog2pdf combines catalog jpeg images into pdfs

Usage

catalog2pdf(keep.img = TRUE, overwrite = FALSE, parallel = 1, path = NULL,
pb = TRUE, by.img.suffix = FALSE, ...)

Arguments

keep.img	Logical argument. Indicates whether jpeg files should be kept (default) or remove.
overwrite	Logical argument. If TRUE all jpeg pdf will be produced again when code is rerun. If FALSE only the ones missing will be produced. Default is FALSE.
parallel	Numeric. Controls whether parallel computing is applied. It specifies the number of cores to be used. Default is 1 (i.e. no parallel computing).
path	Character string containing the directory path where the catalog image files are located. If NULL (default) then the current working directory is used.
pb	Logical argument to control progress bar. Default is TRUE.
by.img.suffix	Logical. If TRUE catalogs with the same image suffix will be put together in a single pdf (so one pdf per image suffix in the catalog images). Default is FALSE (i.e. no suffix).
...	Additional arguments to be passed to the internal pdf creating function pdf for customizing output.

Details

The function combines catalog images in .jpeg format from the catalog function into pdfs. Images must be saved in .jpeg format. Note that using lower resolution and smaller dimension (width and height) when creating catalogs will substantially decrease the size of pdf files (which could be pretty big).

Value

Image files in pdf format with spectrogram catalogs in the working directory.

Examples

## Not run: 
# save sound file examples
data(list = c("Phae.long1", "Phae.long2"))
writeWave(Phae.long1, file.path(tempdir(), "Phae.long1.wav"))
writeWave(Phae.long2, file.path(tempdir(), "Phae.long2.wav"))

catalog(X = lbh_selec_table, nrow = 2, ncol = 4)

# now create single pdf removing jpeg
catalog2pdf(keep.img = FALSE, path = tempdir())

# check this floder
tempdir()

## End(Not run)
