[LincMii]

Does anyone know if there is an image size limit to drawing an image on a 
canvas?

Re: Background image

[LincMii]

This did not work for me ... I am trying to apply this style to a canvas 
but for some reason the image just won't show.

Canvas Background Image

[LincMii]

Hello Everyone,

I am new to the GWT but I decided to get integrated by messing around with 
the canvas! I was trying to implement some animation and a background by 
using the ClientBundle and the HTML5 canvas. The CB is to access my images, 
and then there are three canvas; one for the background, one for moving 
"creatures", and one for user animations (moving a shark with keyboard 
keys). 

So far, everything has been simple, with the exception of one thing. My 
background image will not show! Here is an example: 
http://2.its381b-helloweb-lmii.appspot.com/

And here is a link to the code: 
http://code.google.com/p/sealsurvival/source/browse/trunk/SealSurvival/src/com/hawaii/blt/sealsurvival/client/SealSurvival.java

I am not asking for anyone to "solve" this problem for me, but if anyone 
knows of a glitch w/ the canvas or any special properties that I may have 
missed in using the drawImage() function, I would greatly appreciate the 
tip.

Thanks,

LincMii
