Hi All,
I need to replace white pixels of an image with blue pixels
Does someone have a useful script to do that ?

Thanks
Jean-Marc

Salut Jean-Marc,

here is a little stack that replaces white pixels with blue pixels. Please look at the explanation and the script of the button.



Kind regards

Bernd

Jean-Marc:

Shades of Steve Maller's "ThePixel" XFCN for HC, or Rinaldi's "PixelColor". All from around the Pleistocene.

These returned the value of the pixel under the cursor. But read-only.

And Matthew Reagan wrote a XCMD that would change all the black pixels to any color. close to what you wanted.

It seems impossible that LC does not have a "setPixel" command and "getPixel" function. Could not find one, though.

Ah. So there is such a tool, even though it requires that the entire imageData be processed. Very cool.

Bernd, Craig,

Thank for your fast reply
I will test the Bernd's stack tomorrow

Kind regards
