osascript -e '
set theFile to (open for access POSIX file "test.png" with write permission)
try
write (the clipboard as «class PNGf») to theFile
end try
close access theFile'
in window
powershell -sta '
Add-Type -AssemblyName System.Windows.Forms;,
if ($([System.Windows.Forms.Clipboard]::ContainsImage())) {
[System.Drawing.Bitmap][System.Windows.Forms.Clipboard]::GetDataObject(
).getimage().Save("test.png", [System.Drawing.Imaging.ImageFormat]::Png)
}'
in linux (not test):
xclip -selection clipboard -t image/png -o > "test.png"
if this Addin not work, you can test if this scipt can can generate test.png file when you have a image on clipboard
where is paste image?
for a general Rmd files, all paste image in curr_path/.assets/, named like rmd-img-paste-%Y%m%d%H%M%s.png. If you don't like it, you can specify a subfloder by options(rmarkdown.paste_image_dir = 'you_floder').
for a blogdown post(.Rproj have attr like 'BuildType: Website' and in content/../.., you can override it by options(rmarkdown.is_blogdown_post = FALSE), all paste image in static/post/postname_files/, and
insert code like .
you can specify a baseurl by options(rmarkdown.blogdown_baseurl = 'you_baseurl').
