Re: Pasting text and images together
Do you have access to the Apple Developer web site?
A search didn't tell me much but I find the side terrible useless.
Following a bunch of variable type definitions I wandered to this page:
https://developer.apple.com/documentation/foundation/nsattributedstring/1530578-rtfd
Which also seemed useless to me. I was hoping to find some documentation
that explicitly explained the format, rather than Apple API's to access
the format.
The Wikipedia entry seemed more helpful
(https://en.wikipedia.org/wiki/Rich_Text_Format_Directory) - it appears
teh format is a "bundle" (or folder) of files, including an RTF file and
how ever many media files.
While I don't fully follow this Stackoverflow discussion
(https://stackoverflow.com/questions/18722314/how-to-get-rtf-contents-from-uipasteboard-after-uiwebview-copy)
it appears the clipboard contents is UTF8 encoded, so perhaps doing a
textDecode of UTF8 and then looking at the result may be helpful?

Re: Pasting text and images together
Your right. Something about the rawClipboardData fails with an error. Trying the fullClipboardData (code below) works. My guess is that there may be something about the first key (on my Windows system that is "text/html" where the slash is causing an error? I'd need to look at it further - perhaps skip that key and try others. This may be a bug that may be worth reporting in the LC Quality center. You might get what you want from the fullClipboardData (below) on mouseUp pMouseButton local n=1 lock clipboard -- put the keys of the fullClipboardData into myK3 ## THIS WORKS -- repeat for each line k in myK3 try put the fullClipboardData[k] into temp[n] ## DOESN’T WORK catch myError put myError into e4[n] ## ERROR IS TRIGGERED end try add 1 to n end repeat unlock clipboard end mouseUp On 9/2/2023 5:07 PM, David Epstein via use-livecode wrote: Paul, getting the keys of the rawClipboardData worked for me too.

Re: Pasting text and images together?
You could poke around the raw clipboard data - this is platform specific (in terms of the keys) but gives a complete reflection of the system clipboard: lock clipboard put the keys of the rawClipboardData unlock clipboard This will dump what raw data types are present - then you can fetch using ‘the rawClipboardData[key]’. Note that you need to lock and unlock the clipboard around ‘raw’ access. Warmest regards, Mark.

Re: Pasting text and images together?
If the App copying the mixed content places it on the clipboard as text and an image vs some mixed type, you may be able to do this Your have the on pasteKey message to trap CONTROL/COMMAND-V and if you have a "Paste" menu item, you control the script for that. the ClipboardData, the fullClipBoardData, and the rawClipboardData arrays (see Dictionary entries for each of these) give you access to the different elements on the clipboard. I epect the rawClipboardData will not really apply to this goal, but whether the ClipboardData or fullClipboardData would be better, I'm not sure Essential for either the pasteKey or menu paste action, you scrip wants to put the ClipboardData["text"] into tMyText -- the text copied to the clipboard put the ClipboardData["image"] into tMyImageData -- the text property of an image object As a test, you may need to write a small test handler on pastekey local tClipArray, tFullClipArray put the ClipBoardData into tClipArray put the fullClipboardData into tFullClipArray breakpoint end pasteKey Copy mixed data to your clipboard from your 3rd party app, switch to a test stack with the script above (not tested), and press the paste keys for your OS. The IDE debugger should appear and let you look at the arrays tClipArray and tFullClipArray to see how the data was translated from your 3rd party app. On 9/1/2023 3:32 PM, David Epstein via use-livecode wrote: To clarify my original question: I'm not expecting the built-in paste command to handle this task; I'm wondering if I can script my own paste command to handle it.

As far as I know image data cannot be pasted into LC. I just tried pasting a banal image of a cat from an Ecosia search into a stack directly, and into an image, to no avail. Best, Richmond.
