Usage examples:

PSDPYTHON-278. After the re-export of the PSD file, the result became much larger that original PSD file

        source_file = "input_1129.psd"
        output_file = "output_input_1129.psd"
        source_file_size = os.path.getsize(source_file)

        load_options = PsdLoadOptions()
        load_options.allow_non_changed_layer_repaint = True

        with Image.load(source_file, load_options) as image:
            image.save(output_file)

        # Verify file size
        assert source_file_size * 1.5 >= os.path.getsize(output_file)

        # Verify file can be opened
        with Image.load(output_file) as test_image:
            print("File opened successfully")

PSDPYTHON-279. Refactor layer section resources.

        src_file = "123 1.psd" out_file = "output.psd" load_options = PsdLoadOptions() load_options.load_effects_resource = True # Test before saving with Image.load(src_file, load_options) as img: psd_image = cast(PsdImage, img) assert as_of(psd_image.layers[3].resources[3], LayerSectionResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[8].resources[3], LsdkResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[3].resources[3], BaseLayerSectionResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).length == 4 assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).blend_mode_key == BlendMode.ABSENT assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).subtype == LayerSectionSubtype.NOT_USED psd_image.save(out_file) # Test after saving with Image.load(src_file, load_options) as img: psd_image = cast(PsdImage, img) assert as_of(psd_image.layers[3].resources[3], LayerSectionResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[8].resources[3], LsdkResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[3].resources[3], BaseLayerSectionResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).section_type == LayerSectionType.SECTION_DIVIDER assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).length == 4 assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).blend_mode_key == BlendMode.ABSENT assert as_of(psd_image.layers[8].resources[3], BaseLayerSectionResource).subtype == LayerSectionSubtype.NOT_USED

PSDPYTHON-280. After replacing, the image becomes blurry with jagged edges.

        source_file = "Clipping_Blending.psd"
        output_file = "output_Clipping_Blending.png"

        with Image.load(source_file) as psd_image:
            opt = PngOptions()
            opt.color_type = PngColorType.TRUECOLOR_WITH_ALPHA
            psd_image.save(output_file, opt)

PSDPYTHON-281. Update saving to resource of GradientFillSettings for FillLayer.

		source_file = "ComplexGradientFillLayer.psd"
        output_file = "output_ComplexGradientFillLayer.psd"

        # Edit and save
        with Image.load(source_file) as img:
            image = cast(PsdImage, img)
            fill_layer = cast(FillLayer, image.layers[1])
            fill_settings = cast(GradientFillSettings, fill_layer.fill_settings)
            # Reading
            assert fill_settings.gradient_type == GradientType.LINEAR
            assert fill_settings.gradient.gradient_name == "Custom\0"

            # Editing
            fill_settings.gradient_type = GradientType.DIAMOND
            fill_settings.gradient.gradient_name = "UpdatedGradient"
            fill_layer.update()
            image.save(output_file)

        # Verify
        with Image.load(output_file) as image:
            image = cast(PsdImage, image)
            fill_layer = cast(FillLayer, image.layers[1])
            fill_settings = cast(GradientFillSettings, fill_layer.fill_settings)

            assert fill_settings.gradient_type == GradientType.DIAMOND
            assert fill_settings.gradient.gradient_name == "UpdatedGradient"

**PSDPYTHON-282 . Linear burn blend mode works incorrectly if pixel alpha is less than 255. **

        source_file = "StripesLb.psd"
        output_file = "output_StripesLb.png"

        load_options = PsdLoadOptions()
        load_options.load_effects_resource = True

        pngOpt = PngOptions()
        pngOpt.color_type = PngColorType.TRUECOLOR_WITH_ALPHA
        with PsdImage.load(source_file, load_options) as img:
            img.save(output_file, pngOpt)

PSDPYTHON-283 . The incorrect blending of pixels with transparency for some blending modes.

        source_file = "input.psd"
        output_file = "output_input.png"

        load_options = PsdLoadOptions()
        load_options.load_effects_resource = True

        with PsdImage.load(source_file, load_options) as img:
            pngOpt = PngOptions()
            pngOpt.color_type = PngColorType.TRUECOLOR_WITH_ALPHA
            img.save(output_file, pngOpt)
