I wish this helpful for you getRuntime().exec is for launching an external program. To simple load a file to use in your Java application you can simply treat it like any other file. Indeed if you are using Swing, the ImageIcon constructor will take a String containing the file path as an argument.

Dynamically change an image in a Crystal Report at runtime

Dynamically change an image in a Crystal Report at runtime

I wish this help you At work we do this by pushing the image(s) into the report as fields of a datatable. It's not pretty, but it gets the job done. Of course, this solution requires that you push data into the reports via a DataSet. I've always felt this was a hack at best. I really wish that image parameters were a possibility with CR.
Edit: It's worth noting, if you are binding your crystal report to plain old objects you want to expose a byte[] property for the report to treat that as an image.

will help you I have a window with a title on it. When the user selects a choice from a drop down list, the title image can change. The problem is when the image loads, it's a blurred, stretched, and pixelated. These are PNG files I'm working with and they look good prior to setting the source dynamically. , I can think of two things:
First, try loading the image with:
code :
string strUri2 = String.Format(@"pack://application:,,,/MyAseemby;component/resources/main titles/{0}", CurrenSelection.TitleImage);
imgTitle.Source = new BitmapImage(new Uri(strUri2));

help you fix your problem URLClassLoader can be useful when you need to load newly generated classes at runtime. Unfortunately, you will not be able to reload the definition of a already loaded class (i.e. reload a class) using URLCLassLoader.
code :
FileInputStream stream = new FileInputStream("Path to your class file");
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int data = stream.read();

while(data != -1){
    data = stream.read();


byte[] classData = buffer.toByteArray();

wish help you to fix your issue It's actually something very simple to do.
Request your new data from your web service Get the URL of your new image/logo Use NSURLSession or AFNetworking to request that file Keep the image in a cache so you won't have to re-download the same file twice
Dynamically replace Image in Lottie animation at runtime

To fix the issue you can do Managed to do this: the problem was that my After Effects animation had a vector shape, and I was trying to replace this. After I changed the original animation to have a .png instead, I could replace the Image at runtime. Worked just fine.
code :
// First I converted the png I wanted to see at runtime to a bitmap:

Bitmap bitmapImage = BitmapFactory.decodeResource(getResources(), R.drawable.imageBlah);

// I used the lambda: 

lottieAnimationView.setImageAssetDelegate( lottieImageAsset -> bitmapImage);
