[FR] Make it easier for users to shrink image sizes #614

That's a good idea. I used to manually optimize images. I'll look into tinieR. Thanks! |
|
For pure shrinking of the size for optimization (like tinieR if I understand correctly), I believe For resizing there is also, I think we could make one version based on magick package. (and that is what |

Simply shrinking an image to the desired dimension (i.e. resizing) is easy. Optimizing image losslessly is hard. I just did some quick testing and https://tinypng.com seems to be quite decent in reducing the file size of both PNG and JPG images. |
…d use it: rstudio/blogdown#614) the tinieR package is a more comprehensive implementation of the Tinify API but I only need one feature (i.e. shrink) and the package has several additional dependencies (fs, glue, httr, png, jpeg, rprojroot, yaml)

make the title shorter, otherwise it could be wrapped by `R CMD build` and 'Yihui Xie' will be marked as "mis-spelled" by `R CMD check`
clarify a news item
add a function news2md() to convert package news to Markdown
rstudio/tinytex@4772b5e
add a category argument to news2md() so that category names could be discarded
don't generate the bullet list if all items are empty
BDR suggest authors not use ftp:// sites
fix #52: default to using renv::install() to install packages when pkg_install() is called inside an renv project
forgot to suggest renv
address BDR's request to not use ftp:// (it is still supported, but at some point we may have to only support uploading via https://win-builder.r-project.org/upload.aspx)
default lib = NULL for renv::install() (#52)
add helper functions stop2() and warning2(), which uses call. = FALSE
add a function format_bytes() borrowed from tinytex:::auto_size() and built on top of format.object_size()
add a function tinify() to compress images (e.g., blogdown users could use it: rstudio/blogdown#614)
escape %
move a few functions
rename src to pkg in install_dir(), and factor out the code to build the tarball to pkg_build()
xfun::upload_win_builder() can be called without arguments now
use [[ to get the file instead of list(file); delete the package tarball if it is automatically built
a lightweight version of submit_cran()
ignore readme to avoid CRAN's URL checking

The development version of xfun has a function remotes::install_github('yihui/xfun')If you call it with the argument |
Martin Mächler (1):
specify the default library location since base_pkgs() can "hang"
Yihui Xie (11):
start the next version
roxygenize and bump version
forgot to pass ... to dir.create() in dir_create()
close #68: add support for more file extensions
bump version
factor out a function all_files() that changes list.files()'s default argument values
make it possible to return all logo paths
close rstudio/blogdown#614: add a function shrink_images() to shrink (and optionally compress) images under a directory
also support .webp images
svg images can fail on GHA's Linux machines
CRAN release v0.32
# CHANGES IN xfun VERSION 0.35 - Added a new argument `token` to `protect_math()` to optionally include a token around math expressions. - `base64_uri()` relies less on the **mime** package now. For some common file extensions (e.g., `.jpg`/`.png`), this function knows their MIME types. - `stringsAsStrings()` has been removed from this package. # CHANGES IN xfun VERSION 0.34 - Added a new function `alnum_id()` to generate ID strings from a character vector. - The function `stringsAsStrings()` has been deprecated. # CHANGES IN xfun VERSION 0.33 - Reverted the change for #68: the characters `-+!_#` are no longer accepted by default in filename extensions, since they are relatively rare and caused a breakage in rstudio/bookdown#1369. If you wish to allow for these characters, you may use the new `extra` argument in `file_ext()` and related functions, e.g., `xfun::file_ext(x, extra = '-+!_#')`. - The function `stringsAsStrings()` will be deprecated in a future release of **xfun**, because the global option `stringsAsFactors = FALSE` has become the default in base R since 4.0.0. # CHANGES IN xfun VERSION 0.32 - Added a function `shrink_images()` to shrink images to a maximum width using the **magick** package (thanks, @apreshill, rstudio/blogdown#614). - Added a function `tinify_dir()` as a wrapper of `tinify()` to compress images under a directory. - `file_ext()` supports more file extensions now, such as `.c++`, `.FB2K-COMPONENT`, and so on (thanks, @tentacles-from-outer-space, #68). - Fixed the issue that `xfun::base_pkgs()` could hang R (thanks, @mmaechler, #66). - The `...` argument in `dir_create()` was not passed to `dir.create()`.
I would love a function way to do this, built into blogdown, since I struggle with this all the time!
I also have been looking at: https://jmablog.github.io/tinieR/
Also I know this is important: https://bookdown.org/yihui/rmarkdown-cookbook/optipng.html
It would be cool to offer a way to do this based on regex, like all resize & optimize all images in
