Error when Rendering Images

medini_1056767075

Hi,

I seem to have an error when trying to render Block Diagrams via script. Here is the error message:

I tried to check my code and there seems to be no mistakes. The error happens when trying to call renderDiagram() function from diagram.js library.

What could possibly be the problem?

The following is the script:

function main(){
	//ASK FROM USER, WHERE TO PLACE FILES (Path of Directory or Folder)

	var outputPath = openDirectory("Please select directory");

	if (outputPath) {
		console.log("Output Path: " + outputPath);

		//FIND ALL PJDIAGRAMS INSIDE MEDINI PROJECT
		var allPJDiagrams = finder.findByType(Metamodel.projectmodel.PJDiagram, true).asList();


		//RENDER IMAGES FOR EACH BLOCK DIAGRAM
		for(var i = 0; i< allPJDiagrams .size(); i++){
			var diag = allPJDiagrams .get(i);

			if(allPJDiagrams .get(i).modelID == "SysML"){
				console.log(allPJDiagrams .get(i).name);
				console.log(" " + allPJDiagrams .get(i).mediniIdentifier);

				renderDiagram(diag, outputPath, "PNG");
			}
		}
		console.log("Finished Rendering");

		selectOption("Export Finished", "Export has Finished. File is save in " + outputPath, ["OK"]);
	} else {
		selectOption("No Directory Selected", "You selected no directory. Script will abort", ["OK"]);
	}	
}

Forget it John Paul, I found the issue: to use this particular function you need to have the $ENHANCED_JAVA_ACCESS$ pragma in your first line of the script.

Here a sample to illustrate:

// $EXPERIMENTAL$ $STRICT_MODE$ $WARNING_AS_ERROR$ $ENHANCED_JAVA_ACCESS$
/* 
 * Copyright (c) 2019 ANSYS Germany GmbH
 * All rights reserved.
 */
load(".lib/diagram.js");

function main() {
 if (!selection || !selection.length) {
 throw "Please select a diagram";
 }

 var diagramProxy = selection[0];
 // var diagram = diagramProxy.diagram;
 var imageFolder = new java.io.File("C:\\temp");
 var imageFormat = "PNG";
 var renderedTo = renderDiagram(diagramProxy, imageFolder, imageFormat);

 console.log("Diagram ''{0}'' ws rendered to {1}", diagramProxy.name, renderedTo);
}

main();

Happy Scripting
