Re: Problem saving image for file
It's just how file systems work. If the beginning character is / that means it starts at the root of the file system. Since you had already set the defaultfolder, and wanted to go relative to there, you would just specify the folder name/filename. Or as I said, pre-pend a dot. In fact, 2 dots .. stands for the next folder towards the root so you can do weird things like dir ../../.. which will list the contents of a folder 3 levels above the current. You also don't need to actually set the defaultfolder, you could do as in your example... set the itemDelimiter to slash get the effective filename of this stack put tTempCrop into URL "binfile:" & item 1 to - 2 of it & "/tempMedia/testimage.jpg" In the case of the above you DO need the slash before tempMedia because there is no trailing slash when you get item 1 to -2 of it. But, item 1 to -2 of it is a path starting from the root so you end up with an absolute path rather than a relative path. IE it would be something like /home/username/desktop/mystackfolder/tempMedia/testimage.jpg On Sat, Jul 28, 2018 at 8:45 PM Stephen MacLean via use-livecode < use-livecode@lists.runrev.com> wrote: > Thank you to all who replied! > > Adding the “.” solved the problem and the file saved where it was supposed > to. > > Confusing, because you would think that setting the defaultFolder would > allow you to specify the next sub folder like I did… and it’s not > mentioned, that I saw, in the docs. > > Thanks again! > > Steve > > > On Jul 28, 2018, at 5:52 PM, Mike Bonner via use-livecode < > use-livecode@lists.runrev.com> wrote: > > > > If you use the path /tempMedia that forces it to the root of the > > filesystem and if there isn't a folder /tempmedia, it'll fail.

Re: Problem saving image for file
Thank you to all who replied! Adding the “.” solved the problem and the file saved where it was supposed to. Confusing, because you would think that setting the defaultFolder would allow you to specify the next sub folder like I did… and it’s not mentioned, that I saw, in the docs. Thanks again!

Re: Problem saving image for file
Hi Steve
First, a quick way to the stack or standalone folder is
specialfolderpath(“resources”).
Check that your folders permissions are ok.
export snapshot from rect 0,0,100,100 of this card to url
("binfile:"("resources")&"/Pic.jpg") as JPEG
See if this helps when using your put tTempCrop into url().

Re: Problem saving image for file
If you use the path /tempMedia that forces it to the root of the filesystem and if there isn't a folder /tempmedia, it'll fail. Either leave off the preceding slash, or prepend it with a . <--(a dot) which designates the current directory.

Hi, Try using this syntax: export image "tImage" to file "/tempMedia/testimage.jpg" as JPEG I think you need binfile to read but not to write.
