Digital Workshop

Users creates a collage in the publication. Need to click on the button create a screenshot given area, open a standart dialog window "Save As ..." and save picture to your computer as JPG.

Maybe i need to connect any DLL, but I do not know what it is, what parameters and how can capture screenshot area.

Thanks

There are a few possibilities I can think of, but they involve going outside of Opus to paste the object Frame into Irfanview and save there.

As you don't say, I assume your users may be young children and you want everything done inside the Pub, not launch an image viewer.

I know on the AutoIT (v3) forum (free software) there is a script to create screenshots (maybe with a selectable region). These scripts can be compiled to exe files, and then used from within opus.

Maybe a solution (bit of a workaround, but still)?

you don't say if this can be on a machine you control or the user's own pc..?
If it is on your own controlled PC you can try this:
download "ClipboardCC v 2.5.1". Google for download source. You configure this so that any items added to the clipboard automatically get saved to a designated folder. This will happen continuously while the app is running. The trial version will watermark your saved image, but the licence is really cheap, like NZ$20 (GBP8).

All your images (must be draggable) should be inserted within one frame, e.g. 'pictureframe'. Presumably you will use show/hide buttons outside the frame to decide which ones will be visible, perhaps use script to set layers...

make a button action to copy object (pictureframe) to clipboard.
voila - you will have a jpeg in the designated folder.
---------------------------------
If it is on the users PC and they are reasonably intelligent then use the same copy to clipboard, open MSpaint.exe (maybe you can launch it) and
get them to CTRL_V. They can then save it themselves

Thanks to all responded. I realized that the problem has no solution inside Opus. Perhaps the developers of Opus add this useful feature in future versions of the software. I think it is not difficult (function PrintWindow()).

Lar_123, mac, thank you. Share my publications with Irfanview and ClipboardCC is difficult:) I will try to use the DLL that used these softwares. I do not know the extent legally...

Reemski, the brilliant solution, thank you. I used AutoIt 2 years ago. I will need time to study it again. If will be any results, it will inform you.

Good luck and thank you.

The code i used is the following:




This is a short example but can be used in any way. I would suggest creating a temp file, and then use an save-as box to save the temporary file. The required DLL is attached.

(This is code from someone from the AutoIT forum.)

EDIT: and as i see there is a brilliant capture Reguin function.
parameters for CaptureScreen(filename, jpg quality)
parameters for CaptureRegion are unknown to me. I guess X offset, Y offset, width, height -> but where the quality number is???

Thank you, Reemski, now see your new decision.
But I have, in your advise, solved the problem a little bit different way, but also through AutoIt. I did launch EXE file compiled with the AutoIt`s script.



Everything works fine.

Capture all screen and in parameters need only set the coordinates.
Opus with the AutoIt acquires enormous power:)

Great post! Just what I was looking for. It would be good if this feature was built in.
