A copy of the clipboard on the DC window.
Posted: Tue May 28, 2024 09:01 AM

Using scissors, I cut out a rectangular fragment of the screen and put it on the clipboard.

How can I put an image from the clipboard on the DC of my window ?

Code (fw): Select all Collapse

#include "fivewin.ch"

function Main()

   XImage()

return nil

Is it possible to estimate the size of the fragment in the clipboard ?

Code (fw): Select all Collapse

aImage := FW_ReadImage()  // no params
? aImage[ 3 ], aImage[ 4 ]  // width and height in pixels

If there is no image in the clipboard, these values would be 0,0

Did I understand correctly that FW_ReadImage (without parameters) accesses the clipboard ?

Yes, but if you are using the recent versions. ( FWH2310 and later)
What is the version you are using?
