On the Windows and Mac platforms there is no direct method of printing an image from a file in LiveCode.

In Linux you can shell out to the printer directly.

e.g. put shell(“lpr  myfile.jpg”)

In Widows you can print a text file from the command prompt but an image!

e.g. print c:\file.txt /c /d:lpt1

LiveCode does however allow you to print the rect of a card.

So here is my workaround (solution) for this problem.

We employ the use of two stacks.

PrintControl.livecode & PrintData.livecode

PrintControl allows you to drag an image into a preview area.

The dragged image if first sent to an image holder on the ImageToPrint card of the PrintData stack then the preview is created. The width and height of the PrintData stack is then scaled to match the new image.

on dragDrop

set the filename of image "ImageToPrint" of stack "PrintData" to the dragData["files"]

set the filename of me to the dragData["files"]

if there is a stack "PrintData" then

set the height of stack "PrintData" to the height of image "ImageToPrint" of stack "PrintData"

set the width of stack "PrintData" to the width of image "ImageToPrint" of stack "PrintData"

set the top of image "ImageToPrint" of stack "PrintData" to 0

set the left of image "ImageToPrint" of stack "PrintData" to 0

end if

end dragDrop

on dragEnter

put empty into me

set the dragAction to "copy"

end dragEnter

The Print button on the PrintControl stack opens the print dialogue and prints the ImageToPrint card of the PrintData stack.

on mouseUp

if there is a stack "PrintData" then

answer printer

if the result is "Cancel" then

exit mouseUp

end if

open printing

if the result is not "Cancel" then

print card "ImageToPrint" of stack "PrintData"

close printing

end if

else

answer "PrintData stack not found" with "OK"

end if

end mouseUp

The Reset button just loads up default images into both stacks.

Note> in production the PrintData stack should be hidden or moved off screen.

See the openCard of card Main of stack PrintControl.

--reset start images for both stacks

on openCard

if there is a stack "PrintData" then

--set the visible of stack "PrintData" to false --comment out for testing

end if

send "mouseUp" to button "Reset"

end openCard

--reset start images for both stacks

on mouseUp

   put  image "DragHere" into image "ThumbImage"

   if there is a stack "PrintData" then

      put  image "PrintDefault" of  stack "PrintData" into image "ImageToPrint" of  stack "PrintData"

      set the height of stack "PrintData" to the height of  image "ImageToPrint" of stack "PrintData"

      set the width of stack "PrintData" to the width of  image "ImageToPrint" of stack "PrintData"

      set the top of  image "ImageToPrint" of stack "PrintData" to 0

      set the left of  image "ImageToPrint" of stack "PrintData" to 0

   end if

end mouseUp
