Hi rijaaali,
ok, I think you can create a button, but I will help you with the script, of course
And welcome to the forum!
You can always EXPORT an image from LiveCode to a file on disk:
...
export img "your image here" to file "path/to your/file.png" as PNG
...
Check the dictionary for more info about "export".
fast respons.
Will cost extra!
Best

Hi rijaaali,
you mean let the user decide where to save the image?
Add this to your image export script:
Code: Select all
...
ASK file "Where to save the image?"
put it into tTargetImageFile
## User cancel:
if tTargetImageFile = empty then
exit mouseup
end if
## Add PNG suffix if necessary:
if char -4 to -1 of tTargetImageFile <> ",png" then
put ".png" after tTargetImageFile
end if
## This is only necessary, if you are on a Mac!
set the filetype to ""
## Now export image to file:
export img "your image here" to file tTargetImageFile as PNG
...
Best

Hi rijaaali,
in LiveCode you can start counting from the end
Char -1 = the last char
Char -4 = the 4th last char...? OK, example
This string, filename of an image:
My beatutiful image.jpg
Char -1 = g
Char -4 = .
Char -4 to -1 of that string above = .jpg
So in my example script I check if the user already added the correct file suffix for PNG files,
which is of course not the case, so I add this to the final filename, to get a valid filepathname.
But I'm afraid you need a certain amount of postings before you can add attachments here to your posting.
So just copy/paste your script(s) here...
Best
Klaus

hello mr. klaus..
may u open that?
actually my big problem is, how to fill the white area which has thresholded become a fixie bike with many color.
i mean, when user click in the white area, this app will show a color bucket which is choosen by user. then the white area will change into the color which have been choosen by user.
