Twitter PNG upload somehow converted to JPEG?

Social Media

Having an issue where I’m uploading a PNG via Twitter social pop-up.  It’s definitely a PNG and I’ve checked the file.

By the time it appears on the Twitter time-line it’s a fairly degraded JPG image. My game is quite flat with gradients, so the image looks pretty poor with the JPG artefacts.

[lua]

native.showPopup( “social”,

{

    service = “twitter”,

    message = “I beat level 10!”,

    listener = listener,

    image = { filename=“twitter.png”, baseDir=system.DocumentsDirectory },

})

[/lua]

If I upload a .png from my Photos album using the iOS twitter functionality, it’s a PNG still.

Is this a Corona thing? Or is Twitter auto-converting to jpegs somewhere?

I’ve even tried uploading a high quality jpeg, but it ends up still coming out as a lower quality one.

Appreciate any guidance :slight_smile:

Corona is just passing whatever image you pick  to Twitter.  We are not doing any conversion on the process.

I thought/assumed that was probably the case.

Wonder why it converts from the game, but doesn’t convert from Photo album.
