Export problems
Nov 27th, 2005, 3:36am  
Hi there..
I have made a little drawing app in processing which saves the images drawn on my webpage.
The good part is that it actually works, I can draw images and save them to my webpage thru php using a post script made by Selas and Toxi (i think it was) i found here in the forum.
The bad part is that it only works in "run mode" in processing, when i export the sketch and test it in a browser, it won't show anything.

I'm pretty new to this, so it could be some very basic stuff i need to do/change.

Anyway the non working script + code is here:
http://komputerwolf.com/include/wolfsketchpad_v2/applet/

Any suggestions or answers to the problem will be much appreciated.

If you look in the taskbar(assuming you're using windows), when you have an applet open in a browser, there should be a java icon. If you right click on this, and select "Open Console" you'll get a window, which will contain any error emssages generated by the applet.

In your cas, the applet generates:
Code:
Error while running applet.
java.lang.RuntimeException: background image must be the same size as your application

at processing.core.PGraphics2.background(PGraphics2.java:903)

at processing.core.PApplet.background(PApplet.java:6868)

at wolfsketchpad_v2.setup(wolfsketchpad_v2.java:26)

at processing.core.PApplet.display(PApplet.java:1144)

at processing.core.PGraphics.requestDisplay(PGraphics.java:520)

at processing.core.PApplet.run(PApplet.java:1028)

at java.lang.Thread.run(Unknown Source)


I'm not 100% sure what's causing the problem, since the image appears to be the correct size. Possibly you need to move the background() call to within draw(), or possibly load the image into a PImage before using it in background().

see also the FAQ for this topic:
http://processing.org/faq/bugs.html#applet

the image may not be loading properly or you might not be using size() as the first thing inside setup() (and before you call background). but it's impossible to know without code.
