You may please consider using following example on your end for working with Smart objects.

 public void Test1Smart()
            var filePath = @"mySmartObjectTest.psd";
            var newContentPath1 = @"smartReplace1.png";
            var newContentPath2 = @"smartReplace2.png";

            var pngOutputPath = @"pngoutput.png";
            var psdOutputPath = @"psdoutput.psd";
            using (PsdImage image = (PsdImage)Image.Load(filePath))
                for (int i = 0; i < image.Layers.Length; i++)
                    if (image.Layers[i].GetType().Name.Contains("SmartObjectLayer"))
                        SmartObjectLayer smartObjectLayer = (SmartObjectLayer)image.Layers[i];

                        if (i % 2 == 1)
                        } else

                image.Save(pngOutputPath, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });
                image.Save(psdOutputPath, new PsdOptions(image));

I actually provided the sample to access and work with smart object layer. Please provide the source file and required output file and we will try to help your further in this regard.

Get error

Can you please consider using following sample code on your end. (201.2 KB)

here is my modify (5.4 MB)
the result image looks worse than psd origin


We are looking into this and will get back to you with feedback after investigation.


After investigation we have observed some issue in your example and suggest to uset following:

  1. To use effects, you should be using the following load options:
using (PsdImage image = (PsdImage)Image.Load(srcFile, new PsdLoadOptions() { LoadEffectsResource = true }))
  1. You should change size of text if you want to make image to look fine.
                                        var textData = textLayer.TextData;

                                        textData.Items[0].Text = "Best";
                                        textData.Items[0].Style.FontSize = 170;
  1. When layer effects are loaded and we try to render image and have the blending issue in case of multiple layers. A ticket with ID PSDNET-789 has been created to investigate and resolve this.

when I use this line I get error
NullReferenceException: Object reference not set to an instance of an object.

with this code
image.Save(“result.png”, new PngOptions() { ColorType = PngColorType.TruecolorWithAlpha });


This seems to be a separate issue in API. A ticket with ID PSDNET-792 has been created to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.

Is it possible to achieve my goal with editing text in smart objects?
