Need some help with write_image

jeff hammond

hey guys

i'm trying to do a 2D export via ruby.. i've looked at this:

https://developers.google.com/sketchup/docs/ourdoc/view#write_image

so far, i've tried this:

view = model.active_view status = view.write_image "test.png" keys = { :filename => "~/desktop/write_image.png", :width => 640, :height => 480, :antialias => false, :compression => 0.9, :transparent => true } model = Sketchup.active_model view = model.active_view view.write_image keys

…and it returns 'false'..

not sure what i need to change in order to get the image to write..
any assistance will be greatly appreciated
thanks

Try
model = Sketchup.active_model view = model.active_view keys = { :filename => "~/desktop/write_image.png", :width => 640, :height => 480, :antialias => false, :compression => 0.9, :transparent => true } view.write_image(keys)
Jumbled code from the API - typically confusing
If it fails then try giving the FULL path for the filename [without the '~']...
I'm not sure how a MAC deals with 'relative' / 'user' paths...
On a PC ENV['USERPROFILE'] gives the user's path; onto which you can append 'Desktop'...
The MAC will have something similar...

ok.. that worked.. i tried a few variations on the path and finally got:

/Users/jeff/Desktop/write_image.png

to work..

(whereas Macintosh HD/Users/jeff/Desktop/write_image.png ,which is the full path, fails ?? )

i know with applescript, i can use the tilde in there as a relative path to the user.. i'll just poke around some more and see what i come up with for relative paths in ruby on mac..

thanks a bunch!

oh.. btw.

what i'd really like to do, in this particular scenario, is to write the image to my clipboard instead of creating a file somewhere ..
so, if anyone know of a way to do that, please tell..
thanks

I would know how to do it for Windows, using the Win32API - but I don't know what you can use on OSX.

I think you'll need to at least make a temporary file and use some as/terminal/shell stuff ...
osascript -e "tell app \"Finder\" to set the clipboard to (POSIX file \"~Documents/mytemp.png\")"
perhaps

i think something like that could work.. i found a way to do it with straight applescript (still using a temp file location) which eliminates using Finder..

set the clipboard to (read ("path/to/the/image.png") as «class PNGf»)
