@veerakarthik,

I have observed your comments and created investigation ticket with ID PSDNET-313 to further investigate either your requirements are possible with Aspose.PSD or not. We will share good news with you soon.

@veerakarthik,

I like to share that for PSD files, we recommend to use Aspose.PSD and not Aspose.Imaging. The support for PSD files will no more continued in Aspose.Imaging.

ok thanks,
Aspose.PSD using the psd image layer create an particular layer is ‘BACKGROUND FROM LAYER’

@veerakarthik,

Can you please try to use following sample code on your end and share feedback with us if it helps you.

// Check if Layer is Background
        static bool IsLayerIsBackground(Layer layer)
        {
            return
                !layer.HasAlpha &&
                layer.LayerLock == (LayerLockType.LockTransparentPixels | LayerLockType.LockPosition) &&
                layer.Name == "Background" &&
                layer.Flags == (LayerFlags.HasUsefulInformation | LayerFlags.TransparencyProtected);
        }

        static void MakeLayerToBeBackground(Layer layer)
        {
            layer.Name = "Background";
            layer.LayerLock = LayerLockType.LockTransparentPixels | LayerLockType.LockPosition;
            layer.Flags = layer.Flags | LayerFlags.TransparencyProtected;

            // Removing of Alpha channel
            var channels = new List<ChannelInformation>();
            if (layer.HasAlpha)
            {
                for (int i = 0; i < layer.ChannelsCount; i++)
                {
                    if (layer.ChannelInformation[i].ChannelID != -1)
                    {
                        channels.Add(layer.ChannelInformation[i]);
                    }
                }
                layer.ChannelInformation = channels.ToArray();
            }
        }

        // Example code
        string sourceFileName = "Background.psd";

        // Background layer is created in PhotoShop
        using (var psd = (PsdImage)Image.Load(sourceFileName))
        {
            var layer = psd.Layers[0];
            if (!IsLayerIsBackground(layer))
            {
                throw new Exception("Layer is not Background");
            }

            // Check if after the save layer stays background
            var outputBackgroundPath = "output.psd";
            psd.Save(outputBackgroundPath, new PsdOptions());
        }

        // In this case input image hasn't background layer
        sourceFileName = "NotBackground.psd";

        using (var psd = (PsdImage)Image.Load(sourceFileName))
        {
            var layer = psd.Layers[0];

            if (IsLayerIsBackground(layer))
            {
                throw new Exception("Layer must not be Background at the start");
            }

            // We can make bakground
            MakeLayerToBeBackground(layer);

            if (!IsLayerIsBackground(layer))
            {
                throw new Exception("Layer is not Background");
            }

            // Check if after the save layer became the background layer
            var outputBackgroundPath = "outputCreatedBackground.psd";
            psd.Save(outputBackgroundPath, new PsdOptions());
        }
