Adolfo Benedetti:
this should be a blocking issue, with java 6 as well;
How can we deploy themes without a consistent gif encoder?
java version "1.6.0_51"
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-456-11M4508)
Java HotSpot(TM) 64-Bit Server VM (build 20.51-b01-456, mixed mode)
After looking at this for a while, we've concluded that a recent JDK/JRE update (Java 6 build 51 and later, and Java 7 as well, though I'm not sure which update) has changed the way in which the JRE libraries process images, which code in Liferay was not prepared to deal with. Certain types of PNGs wreak havoc with some code in Liferay. In other words, it's a bug
The workaround is to remove or replace the following files (ideally before you start up Liferay for the first time):
./ROOT/html/themes/_unstyled/images/calendar/calendar_drop_shadow.png
./ROOT/html/themes/classic/images/calendar/calendar_drop_shadow.png
./welcome-theme/images/calendar/calendar_drop_shadow.png
If you remove them, of course, your calendar would likely be missing a shadow effect. If you elect to replace them, you can just open the file with your favorite image editor and re-save it using the RGBA color space (as opposed to the "gray+alpha" color space, which is what is screwing up some calculations in Liferay code).
I think I found a solution for this bug in the SDK.
I started a brand new theme this morning and I had the error. i couldn't deploy the new, currently empty theme at all. Our environement was using Java 1.6.0_51 with Liferay 6.1.20 GA2.
I simply tried to add a liferay-look-and-feel.xml in the WEB-INF directory like the old SDK did.
Deployed the theme and Liferay installed it without the Incorrect scanline stride: 32 error.
Hope this can help others, this bug can be quite frustrating.
Can someone confirm this workaround/bug?

This solution worked for me. I am currently using liferay-portal-6.1.1-ce-ga2
Had to remove "<" and ">" from "<THEME ID>" and <THEME NAME> though.
Thanks for this quick fix!
