I am working on Roku application and sending static images to Roku for display of weather info.

If this.content.WeatherImagePath <> Invalid
 this.bitmaps[this.content.WeatherImagePath] = {
        request: Invalid,
 tries: 1,
        bitmap: CreateObject("roBitmap", this.content.WeatherImagePath),
 done: True
    }
 End If

I am using this images to display:

But I getting color of sun in Blue.
 for details of images (http://stackoverflow.com/questions/42413659/roku-sometime-changes-the-color-of-static-images) 

Memory detail is:
Available memory 14927808 used 24072192 max 39000000
What can be issue ?

i've seen that before often, with blue images they would appear orange, basically the colors appear inverse.  After messing around with it a few times I chalked it up to a firmware bug, i don't know but seems as if there's something about the image preparation that makes it more or less likely to happen, since it always happened for certain images for me.

Can you provide the specific image file being used, e.g. by giving a link to the file on your webserver or public dropbox?

Then, on what Roku model(s) do you see the problem? If you can provide the Model info from the Settings / System / About that will help.

In topic i have added an image and link is also there for output images.
I am facing this issue on almost all models.
But sometimes roku displays images as it should means color of sun is yellow. but sometimes color of sun is bule.

What API are you using (e.g. roScreen, roImageCanvas, roSgScreen/RSG)?
It will help if you share specific model number (e.g. 3600x, 2700x...) and firmware version where you "get the blues".
Also, i am not sure that imgur (what you use for to share the image) doesn't mangle the image even a little and that might be significant, e.g. i see it's a png with alpha.

I looked at stackoverflow and I didn't see an image of this graphic displaying correctly, the ones that were yellow were different graphics. Obviously it shows correctly here. I don't see a reason but it does appear that the white/grey of the clouds is correct which rules out any bizarre channel swapping in the file or the Roku. Have you tried starting with a fresh graphic and pasting the layer in?

Well, yellow is the inverse of blue if you subtract each component from 255 (yellow = ffff00, blue = 0000ff), while gray is approximately a self inverse if it's close to 808080.  White is harder to explain, that should change to black under this theory.

Or it could have something to do with the last verse of Scarlet Begonias.  🙂

Exactly! I did check the inverse and it's a considerably darker shade that what's showing.

can alfalpha channel affect that?
