request pdf export

[dvdrbls]

Thank you for this awesome library, the images are so beautiful, is there an option to create pdfs instead of png files?

Thanks again, David

hey, thank you!

Yes, ggsave() let's you export an image as a pdf as well. See: https://ggplot2.tidyverse.org/reference/ggsave.html

In order to work with generativeart, add thedevice-paramter to the generate_plot() function like this: ggplot2::ggsave(plot, filename = paste0(IMG_PATH, file_name), width = 6, height = 6, device = "pdf")

Does this help?

Best, Katharina

Thank you, I am a beginner and barely able to understand the code most of the time, it gives me an error, can you help? Thanks

`library(generativeart) library(ggplot2)

set the paths

IMG_DIR <- "img/" IMG_SUBDIR <- "everything/" IMG_SUBDIR2 <- "handpicked/" IMG_PATH <- paste0(IMG_DIR, IMG_SUBDIR)

LOGFILE_DIR <- "logfile/" LOGFILE <- "logfile.csv" LOGFILE_PATH <- paste0(LOGFILE_DIR, LOGFILE)

create the directory structure

generativeart::setup_directories(IMG_DIR, IMG_SUBDIR, IMG_SUBDIR2, LOGFILE_DIR)

include a specific formula, for example:

my_formula <- list( x = quote(runif(1, -6, 1) x_i^4 - sin(y_i^1)), y = quote(runif(1, -1, 1) y_i^1 - cos(x_i^4)) )

call the main function to create five images with a polar coordinate system

generativeart::generate_img(formula = my_formula, nr_of_img = 1, polar = FALSE) ggplot2::ggsave(plot, my_formula = paste0(IMG_PATH, file_name), width = 6, height = 6, device = "pdf")`

Hey, I updated the package and you can now choose the filtetype in the main function. The default is png, but you can choose a pdf like this: generativeart::generate_img(formula = my_formula, nr_of_img = 1, polar = FALSE, filetype="pdf")

Update/Reinstall the package and then it works

Thank you! This is so great
