The constructor "Sdrop(xx_xx)" does not exist.

Hi, I am working on a code (still really new) and I get the error of : The constructor "Sdrop (knitty_main)" does not exist.

void setup() {
  dh = new DisposeHandler(this);

  knittySettings = new JSONObject();``

  size(1270, 750);

  UsedFont = createFont("Arial", 16, true); 


  //load Logo
  knittyLogoImage = loadImage("knitty_logo_80px.gif");

  displayButtonsGUI(); //GUI tab
  drop = new SDrop(this);
  //load BasicSettings
  knittySettingsName = "data/BasicKnittySettings.json";
  loadKnittySettingsFile();

}

Here is the code that the error links to, and the line of code that is highlighted by the error is : drop = new SDrop(this);

I am just trying to get this code to run, so that I can then use the language to alter this sketch to suit my needs. If i have asked this in the wrong place or wrong manner, I apologies.

what imports are you using? how and where is drop defined? what is SDrop?

jojo13

import g4p_controls.*;    // sourceforge.net/projects/g4p/
import sojamo.drop.*;    //  www.sojamo.de/libraries/drop/

These are the inputs.

SDrop drop; //drop pictures

I think this is where it is defined.

This is a Github sketch, and I am trying to get it to work so that I can learn how It was created. It controls a knitting machine with an Arduino. I am new to the processing language, so if there is good material I need to read, please let me know.

I want to use Processing to make a GUI that allows images to be converted to a pixel by pixel file that can be transmitted to a knitting machine to select needles to select the needles that work with each colour. This sketch is the basics of what I want to do, so If I can get it going it would be a great "reference" for what I want to do.

You need to look at the documentation of SDrop - maybe the number of parameters is wrong

Could be ...(this, 200,200);

or anything

the example here seems to match

http://www.sojamo.de/libraries/drop/examples/DropBasics/DropBasics.pde

BUT....

"Last update, 05/09/2010."

"Platform osx,windows,linux Processing 1.1"

old...

happily:

https://github.com/transfluxus/drop

"port of sojamo's drop library to Processing 3"

koogs

in fact, that last one is in the library list. you should be installing it using the library manager.
