Public API Changes

Added APIs:

• P:Aspose.PSD.ImageOptions.PsdOptions.BackgroundContents
• P:Aspose.PSD.FileFormats.Ai.AiLayerSection.HasMultiLayerMasks
• P:Aspose.PSD.FileFormats.Ai.AiLayerSection.ColorIndex

Removed APIs:

• None

Usage examples:

PSDPYTHON-59. Semi transparency is processed wrong on the psd file preview

// Semi transparency is processed wrong on the psd file preview.
// BackgroundContents assigned to White. Transparent areas should have white color.

        sourceFile = "frog_nosymb.psd"
        outputFile = "frog_nosymb_backgroundcontents_output.psd"

        with PsdImage.load(sourceFile) as psdImage:

            backgroundColor = RawColor(PixelDataFormat.rgb_32_bpp, 0)

            argbValue = ctypes.c_int32(255 << 24 | 255 << 16 | 255 << 8 | 255).value

            backgroundColor.set_as_int(argbValue)  # White

            psdOptions = PsdOptions(psdImage)
            psdOptions.color_mode = ColorModes.RGB
            psdOptions.compression_method = CompressionMethod.RLE
            psdOptions.channels_count = 4
            psdOptions.background_contents = backgroundColor

            psdImage.save(outputFile, psdOptions)

PSDPYTHON-60. [AI Format] Add support for handling AI Files with EPSF header

        sourceFile = "example.ai"
        outputFilePath = "example.png"
       
        def assert_are_equal(expected, actual):

                raise Exception("Objects are not equal.")

            image = cast(AiImage, img)
            assert_are_equal(len(image.layers), 2)
            assert_are_equal(image.layers[0].has_multi_layer_masks, False)
            assert_are_equal(image.layers[0].color_index, -1)
            assert_are_equal(image.layers[1].has_multi_layer_masks, False)
