screen captures

[churchken]

Hi,

Is there a way using REV commands to capture a specific screen area (or designated window) and put it into an image?

Thanks,

Hi Ken,

sure it is

Check the docs for "import snapshot..."

Klaus,

Many thanks for the spot on reference.

Hi,

Using the "export snapshot" command, an area of the screen is sucessfully exported to an image file.

Now, is there a way to capture the rectangle x & y values of the capture area so that the same area may be captured at timed intervals?

I've tried the clickLoc and mouseLoc commands, but don't seem to actually "catch" the precise area that was defined in the "export snapshot" process.

Thanks in advance for any pointers.

Hi ken,

What exactly have you tried so far?

You can import/export a snapshot from the rectangle (or a part of it) of any object. It is all explained in the docs. For example:

export snapshot from rect 100,100,200,200 of this card to myVar as PNG

If you need the user to select a part of the card, you should give sufficient visual feedback. For example, set the topleft of an object to the mouseLoc on mouseDown, followed by a repeat loop which sets the bottomright of the object to the mouseLoc. When the mouse is up, put the rect of the object into a variable and use that to export from.

Best,

Mark
