Viewports: images on WPS are not being displayed

[bzavala]

Hi all...

I just took today's SVN. Since viewports for WPS has been commited, I decided to try a WPS theme I'm working on right now, using viewports.

All the lines are being displayed fine. My album art is displaying fine, but the battery level, volume levels, play/pause and all other icons, are not being displayed.  

I read somewhere that there is a limit on the amount of images and amount of size that is loaded, so I limited it to only 5 small images (play, pause, rewind, foward, hard drive activity) but still, with only these 5 images, I am unable to display them at all.

Has anybody been successful in creating/porting a theme to use viewports? It must have been a recent changed that I missed, since I was able to make it work a couple of weeks ago when there was a thread on the unsupported builds forum.

Thanks in advance,

Ben

Which revision is your build?

[linuxstb]

As Llorean implied, please make sure you're running the very latest current build - there have been a few bugfixes committed related to viewports.

If you still have the problem, can you attach your .wps file?

I had this problem too. I fixed it by puting all my image code and image conditions before the viewport code(I usally put them at the end).

I am using r16796-080325 and the issue still happens.

I did what Hweb21 suggested and I put all the images before the viewports and that fixed it.  So thanks!!

I am having another issue now: I am getting white lines over the album art.. it might be because I am placing viewports to the left of the album art image. I'll play around with it and report any issue I find.

Thanks again all!

Ben

EDIT: Now that I think about it... is a viewport necessary for the albumart itself?

[linuxstb]

My advice would be to split your WPS into a set (you can have up to 15) non-overlapping viewports, and draw all the different elements of your WPS into those viewports.

Everything before the first %V line is drawn in a default full-screen viewport - but this is mainly for backwards compatibility - for new WPSs I would suggest not using the default.

And remember that all items (including images displayed with %xd) are drawn on the screen relative to the viewport they are contained in - so the co-ordinates you give the image with %xl must be relative to the viewport, not relative to the top-left corner of the screen.  This seems to be the most common mistake.

And to answer bzavala's question, yes, I would put albumart in its own viewport.

[bzavala]

great... using multiple viewports for each section works fine; this fixed the blank lines over the album art.

I ended up using 13 viewports but it worked. I know the limit is 15.

Thanks linuxtb!
