IViewer 4 v4.0.241

[Clayton Vicente]

I made the huge mistake to update my IViewer before confirm that some problems have been solved, now i loose all my thumbs inclination in my .gui. I made a .gui exemple like you guys ask me, i send my .gui too, i was waiting for some feedback before update my IViewer, i just forgot and made the update. I had relating this several times, but until now i dont get any feedback if this will be fix or not.

Now, can you guys tell me if this will be fix ?

I get another strange behavior too. The thumbs for my lists only showing after i show and hide a item (list scrolling). See the picture. When i scroll the list i get this blue icon, not matter how many time i wait, this blue icon don't hide and the thumb dont show. After i scroll the list again and return for the same position i can see the thumb.

Everything was working fine in the previews IViewer

Thanks

There is a change coming to not show the missing image icon, but that doesnt explain why you are getting it in the first place.
Sounds like you are using an image URL that doesnt exist initially. Try changing it to some default blank image.

Not sure what you mean by this:

"now i loose all my thumbs inclination in my .gui."

My english its bad, you know that.

Everything was working perfectly in the previous IViewer, so i think there is nothing wrong with my image, and yes, its a URL image that i get from xbmc.

I had explain the problem with the inclination in the IViewer next several times. I made a example .gui several weeks ago showing the problem and made a video too.

Anyway, this is the video showing the problem using yrotation, i just set the yrotation to -10 or -20 to get a inclination. You can see that in the previous version of IViewer the main thumb have a inclination. You can test this in the .gui that i send, i am sending again. Change the yrotation value for 45 or whatever and you see that there is no inclination anymore.

I get another problem with the yrotation too, but i will have to make a  video showing the problem. In resume, there is something wrong with the yrotation, and this blue image its awkward and detract the interface.

Thanks.

OK, so the rotation angles again - yes we have that GUI and will be looking into it.

Lets focus on the image placeholder issue you are having first - set the image to point to a blank png image first, rather than nothing or a URL which might receive a 404 on launch.

I also see problems with the placeholders. I'm quite certain that the problem exist even though all images are cached, no URL image is used and an default image is used. I have a case that sometimes displays for media item icons that represent the video/audio format of movies. At first selection of a movie a media icon can be a placeholder, selection of another movie and then the first movie again and the correct image is displayed. These icons are cached and not dynamically loaded.

I also have a another case where placeholders are displayed in a list the first time the list is filled. I have checked the gui XML and everything seems fine but the list is filled during initialization so something could be missing at that point. Need to debug to check this.  

I played yesterday with a slider animation that was based on 19 images. All images are cached. Sometimes the placeholder was displayed during the first run of the animation. So my guess is that a placeholder can be displayed if the image is not accessed from cache withing a certain time. This time could be too long if the image never has been displayed one screen before, even though it exist on an cache page. Does this make sense? 

The long term plan is really good, I have been missing the feature to have default images when an image thumb fail to load. However, I have worked around this by placing default images behind the actual thumb, relying on that an image that fail to load display as blank. The current behavior of Next version brake this feature.

It's also very good during development to see the missing images.

People will have issues with missing images with this version and it can be time consuming to clean this up, although it should be done. I suggest a quick update of iViewer Next that turn off the use off global placeholders. That will give time for fixing the issues in the TF version. It was too little time, for me, between TF and Next release to report this.

Okay we're going to push a hotfix update today to remove the placeholder image, until we have a mechanism that satisfies everyone.

Great!

One performance thing related to using images that do not have the correct pixel dimensions in lists. In general one should not use images of other dimensions since they need to be rescaled on the fly and that is really bad for the list scrolling performance. Does the same apply for fully transparent pngs?

Several of our lists uses a blank background for every second list item. These lists do not use any thumbs and only contain little graphics. I use a small blank image that is fully transparent for all these backgrounds that should be blank, i.e. it need to be rescaled. Should we create a blank image with correct dimension for each list item instead or should the list item be set as an empty string, i.e. "" ?
