LoadImage using Microsoft's VM JView
« on: Feb 28th, 2004, 3:19am » |

BImage truck;
void setup() {
truck = loadImage("truck.gif");
}
void loop() {
image( truck, 20, 20 );
}

Using Microsoft's VM, I am unable to load BImages from jar files made by processing.
I am calling Microsoft's VM from the command line (JView).
On a related note, I am able to load BFonts.
Thanks.

hmm.. what does unable to load mean? that you get exceptions? that it doesn't do anything?
loading images is pretty basic functionality so i'd be surprised if it didn't work..

When run from a jar using Microsoft VM JView, after calling:
BImage truckImage = loadImage("truck.gif");
System.out.println( "dim: " + truckImage.width + ", " + truckImage.height );
the BImage object's width and height are -1. The gif is not displayed in the loop method either.
The same jar, made from P5 68, loads the image in successfully (has a non negative width and height and is displayed) using sun's 1.1.8 vm.
Thanks.
the calls:
C:/jdk1.1.8/bin/appletviewer index.html
and
jview /a /cp:p JViewTest.jar JViewTest
winxp with JView installed.

try putting the file on a web server, and use
jview /a http://blahblah/index.html
you might be running into a security problem. in some cases, the msft vm won't give you access to things if it figures out that you're loading from a local file.
(this is not to say that it's not a bug, it's just something to try before we mark it as such...)

that works. i can see the image using JView now that the applet is up on the web.
in summary: BFonts load okay locally, but BImages do not when using the Microsoft VM JView.
fix: put your applet onto the web, where the Microsoft VM will be able to load in everything.
