I'm using a PosterGridView and display multiple posters in Roku. I use a transparent image in a poster. Is there any way to change background Like white or blue using a poster grid?

I used poster grid view like below :

<PosterGrid 
id = "ChannelPosterGrid" 
translation = "[ 10 , 10 ]" 
caption1NumLines = "2" 
caption2NumLines = "2"
numColumns="4"
numRows="6"
focusBitmapUri="pkg:/images/imagegrid.png"
itemSpacing = "[ 20, 20 ]" /> 

In a .brs file access like simply :

m.top.grid = m.top.findNode("ChannelPosterGrid")

I have tried three things :

m.top.grid.backgroundURI = "pkg:/images/myImage.jpg" 'not work
m.top.backgroundURI = "pkg:/images/myImage.jpg" 'not work
scene.backgroundURI = "pkg:/images/white.jpg" 'Its set hole screen background 'scene is object of roSGScreen

Here, I set an image using hdposterurl and sdposterurl. But, Here I getting a transparent image with black color. And My background is also black. So, The Image is mixed-up with the background. So, I required to find a way to put a white rectangle behind of image. It's Possible with RowList. Because of the Poster node used inside a RowList. But, I try to find out with PosterGrid. Any Solution for this issue.

It would be nice if poster grid had an "itemComponentName" field.  Have you tried "imageWellBitmapUri"?

I tried this field(imageWellBitmapUri). But, It does not work with Empty Poster Grid in my case And I don't try to do this way. I tried to put a white image or Rectangle behind the black transparent images. I required it because here my images are black transparent and my background is also black. So, Images Merged with the background.
I want to do something like this in the PosterGrid. Here Sample in Poster Node.

<Rectangle id="testRectangle" color="0xFFFFFFFF">
<Poster id="poster"/>
</Rectangle>

m.background = m.top.findNode("background")

m.background.uri = "pkg:/images/Envoi.jpg"

You want to migrate everything from the PosterGrid into the MarkupGrid. MarkupGrid has an ItemComponentName you can extend to build whatever you need logic/render wise.

The PosterGrid is for porting old SDKA applications into a standard look without having to design anything.

SHORTDESCRIPTIONLINE1	string	The text for the first grid item caption.
SHORTDESCRIPTIONLINE2	string	The text for the second grid item caption.

The PosterGrid is just an old repurposed roGridScreen. Those fields are originally from the roGridScreen.

PosterGrid is (practically?!) useless. In most cases you will want to immediately forget it even exists and skip right to MarkupGrid, learn it, and implement that instead.

I cannot understand why PosterGrid is not deprecated out.
