java.io.FileNotFoundException: .\marvin\plugins\image\org.marvinproject.image.transform.scale.jar

[Herc K.]

Hello guys. I'm new here and I have a problem with the framework. 

So I'm making a simple image viewer in Java and I'm using this framework. It's really cool but I get this error when I try to use the scale plugin.

I have imported the MarvinPluginCollection like this: "import marvin.MarvinPluginCollection;"

and I try to use the scaling plugin like this: "MarvinPluginCollection.scale(image.clone(), image, zoomLevel*image.getWidth(), zoomLevel*image.getHeight());"

I always get the above error though. What am I doing wrong?

Full error output:

java.io.FileNotFoundException: .\marvin\plugins\image\org.marvinproject.image.transform.scale.jar (The system cannot find the path specified)

I think you've not properly configured Marvin in your project. Marvin is looking for the scale implementation (scale.jar) and it was not found. Did you place marvin folder in your project root folder? If you placed it on another location, did you set the new path using MarvinDefinitions.setImagePluginPath(path)?

Please, check the READ-ME file and the following links:

Good luck!

Thank you for your response. Turns out you are right. I thought I only needed to add the marvin jar and not anything else. After adding all of the file on the correct location, it fixed the problem. 

However now I have another problem. In my application there is a zoom function and that's what I use scale for. But after I zoom in a couple of times (the new image scale is basically the old width plus 2*zoomLevel) the image first becomes kind of transparent and then disappears. Why is this happening.

[Gabriel Ambrósio Archanjo]

Please, share the code of the your software module doing the scale using Pastebin (http://pastebin.com/) or similar sharing tool.
