How do you copy image data from the clipboard?

in Programming Questions • 2 years ago

Is there any code available to copy image data from the clipboard and use it in processing.

The alternative is convert the image to text copy it to the clipboard and then copy the text from the clipboard to image,
manipulate it and then copy the image back to the clipboard.

Either method requires a knowledge of both readying and writing image data to and from the clipboard.

reposting the code by PhiLho from owaunandrew's like above.

works for me (osx) when copy/paste images from a browser or photoshop. copy/paste an image file from the finder does not work for me though. i guess because here the DataFlavor is not an image but a file.

in case you want to copy images from processing to the clipboard, see this post in the wiki Copy_image_to_clipboard

import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.Transferable;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.UnsupportedFlavorException;
String pastedMessage;
PImage pastedImage;
void setup()
{
size(800, 200);
PFont f = createFont("Arial", 12);
textFont(f);
}
void draw()
{
background(255);
if (pastedImage != null)
{
image(pastedImage, 5, 5);
}
if (pastedMessage != null)
{
fill(#008800);
text(pastedMessage, 5, 15);
}
}
void keyPressed()
{
if (key == 0x16) // Ctrl+v
{
pastedMessage = GetTextFromClipboard();
pastedImage = GetImageFromClipboard();
}
}
String GetTextFromClipboard()
{
String text = (String) GetFromClipboard(DataFlavor.stringFlavor);
return text;
}
PImage GetImageFromClipboard()
{
PImage img = null;
java.awt.Image image = (java.awt.Image) GetFromClipboard(DataFlavor.imageFlavor);
if (image != null)
{
img = new PImage(image);
}
return img;
}
Object GetFromClipboard(DataFlavor flavor)
{
Clipboard clipboard = getToolkit().getSystemClipboard();
Transferable contents = clipboard.getContents(null);
Object obj = null;
if (contents != null && contents.isDataFlavorSupported(flavor))
{
try
{
obj = contents.getTransferData(flavor);
}
catch (UnsupportedFlavorException exu) // Unlikely but we must catch it
{
println("Unsupported flavor: " + exu);
//~ exu.printStackTrace();
}
catch (java.io.IOException exi)
{
println("Unavailable data: " + exi);
//~ exi.printStackTrace();
}
}
return obj;
}

I can gather from the clipboard to a string.

Do I have to write an algorithm to convert it to an array.
loadStrings() works but for physical files.

I may have to look at the loadStrings() code on google and see how I can create my own to create an array of String from the clipboard.

Perhaps use split() to get an array of strings.

Thanks that works when I use

lines = split(copyfromclipboard(),'\n');

\n is the line feed

Works like a charm... thanks!
