Usage examples:

PSDPYTHON-276. IndexOutOfRangeException in the large file 2500x36667 (DPI 300).

sourceFile = "blind3_nolock.psb"
outputFile = "blind3_nolock.png"

loadOpt = PsdLoadOptions()
loadOpt.load_effects_resource = True

with PsdImage.load(sourceFile, loadOpt) as img:
    psdImage = cast(PsdImage, img)
    layers = psdImage.layers
    pngOpt = PngOptions()
    pngOpt.color_type = PngColorType.TRUECOLOR_WITH_ALPHA
    psdImage.save(outputFile, pngOpt)

PSDPYTHON-286. The file loses a large amount of resources after saving.

    options = PsdOptions()
    assert options.resources is None

    imageResourcesCount = len(psdImage.image_resources)

    assert options.resources is None

# Verify resources count after default save
with PsdImage.load(outFile) as img:
    psdImage = cast(PsdImage, img)
    assert imageResourcesCount == len(psdImage.image_resources)

# Save without resources
with PsdImage.load(srcFile) as img:

    options = PsdOptions()
    options.resources = []
    assert len(options.resources) == 0

# Verify resources count after saving without resources

    assert DefaultResourcesCount == len(psdImage.image_resources)

# Save with several resources

    psdImage = cast(PsdImage, img)
    psdOptions = PsdOptions()
    newResources = []
    newResources.append(PrintScaleResource())

PSDPYTHON-287. ArgumentException on loading section resource.

PSDPYTHON-288. SmartObjectLayer the size is changed after setContents and updateModifiedContent.
