Displaying Transparent PNG Image.

[Mikhail]

Good Day, everyone!

Is there a way to display transparent PNG images in Isadora?

I can't find information about this theme. Can someone help me? Isadora example project would be best!

I need to display transparent logo above all layers.

Thanks in Advance.

You can just do it....

If your PNG file already has a transparency then that transparency will work.
Import the PNG file into your project.
Drag it from the bin onto the stage which will automatically create a picture player.
Set the blend to transparent.
Set the layer to a higher number than anything else
Reposition it to where you want it.

HTH!

Thanks [mark_m](http://troikatronix.com/troikatronixforum/profile/8122/mark_m) for your reply, 

You're right! everythings works fine! But in my main project i use Scaller to stretch Images to screen edges. And I found when i use scaller, transparent areas becames unusial(see attachments, I marked these areas, by arrows),

That's interesting.

Did you make the .png file yourself? Do you think they could be stray, non-transparent pixels which we only see when they're stretched bigger through your use of the scaler?

@Mikhail,

OK, I just tested this in v2.2.2\. with a transparent PNG and saw a problem. There is however a workaround for you until I get this fixed.

If you haven't already, install the "TroikaTronix FreeFrameGL Plugin Collection – Installer" –– it is under "Related Downloads" on this page

and install them. Place the FFGLPremultiply actor after the Picture Player and before any other actors. Then the transparency will work.

I have filed a bug report for you. You don't need to file one yourself.

Best Wishes,

Mark

Hi,

I am just curious if the problem @Mark identified with transparent PNG files has been fixed in V245b16 ?

I am getting some recurring irregular drop out of image information when using PNG transparency through Picture Player and 3D Rect Project. The image segments are layered and slightly offset / rotated. There are 4 x transparent PNG files that make up the attached screengrabbed image that are rendered to a Virtual Stage located in a control scene. The image appears complete for a number of activations and displays with irregular dropout for others. I have added the FFGLPremultiply between the Picture Players and the 3D Rect Project actors however the irregular dropout appears to persist.
