使用例:

PSDPYTHON-50. [AI形式] XObjectFormリソース処理の追加

        sourceFileName = "example.ai"
        outputFilePath = "example_output.png"

        with AiImage.load(sourceFileName) as image:
            image.save(outputFilePath, PngOptions())

PSDPYTHON-51. ShapeLayerのためのコンストラクタを追加

     def check ShapeLayerConstructor():
        outputFile = "AddShapeLayer_output.psd"

        with PsdImage(600, 400) as newPsd:
            shapeLayer = newPsd.add_shape_layer()

            newShape = generate_new_shape(newPsd.size)
            newShapes = [newShape]
            shapeLayer.path.set_items(newShapes)

            shapeLayer.update()

            newPsd.save(outputFile)

        with PsdImage.load(outputFile) as img:
            image = cast(PsdImage, img)
            assert len(image.layers) == 2

            shapeLayer = cast(ShapeLayer, image.layers[1])
            internalFill = shapeLayer.fill
            strokeSettings = shapeLayer.stroke
            strokeFill = shapeLayer.stroke.fill

            assert len(shapeLayer.path.get_items()) == 1
            assert len(shapeLayer.path.get_items()[0].get_items()) == 3

            assert internalFill.color.to_argb() == -16127182

            assert strokeSettings.size == 7.41
            assert not strokeSettings.enabled
            assert strokeSettings.line_alignment == StrokePosition.CENTER
            assert strokeSettings.line_cap == LineCapType.BUTT_CAP
            assert strokeSettings.line_join == LineJoinType.MITER_JOIN
            assert strokeFill.color.to_argb() == -16777216
