Export PSD layers as separate PNG files, while retaining artboard cropping

Aspose.PSD Product Family
1

I have this test code that exports PSD layers as PNG images, but by default it seems the tool exports the entire layer. What I’ve been unable to find in the documentation is a way to crop the exported layer to the same size as the PSD artboard. In the example PSD I’ll attach, you can see the entire circle is visible even though the artboard is too small to contain that shape.

Is this something Aspose PSD supports?

@tcaruth,
If I correctly understand, you want the result images will have the size of the whole PsdImage and render with a saving layer position.
To get this result try to replace this section of your code:

        // Write this layer to disk
        objLayer.save(strSavedLayerName, pngOptions);

by next code example:

        // Write this layer to disk
        Rectangle savingBounds = new Rectangle(-objLayer.getLeft(), -objLayer.getTop(), psdImage.getWidth(), psdImage.getHeight());
        objLayer.save(strSavedLayerName, pngOptions, savingBounds);
