Usage Examples:
IMAGINGPYTHONNET-533 CDR rendering produces all-black (PDF/vector) or blank (raster) output
### Case A: CDR → PDF produces an all-black page
from aspose.pycore import cast
from aspose.imaging import Image, SizeF, Color
from aspose.imaging.imageoptions import PdfOptions, CdrRasterizationOptions, PositioningTypes
# Code used ---- Case A: CDR → PDF produces an all-black page ----
with Image.load("Monthly Music - 03 March.cdr") as image:
cdr_options = CdrRasterizationOptions()
cdr_options.page_size = cast(SizeF, image.size)
cdr_options.positioning = PositioningTypes.DEFINED_BY_DOCUMENT
cdr_options.background_color = Color.white
pdf_options = PdfOptions()
pdf_options.vector_rasterization_options = cdr_options
image.save("out.pdf", pdf_options)
### Case B: CDR → PNG produces a blank image
from aspose.pycore import cast
from aspose.imaging import Image, SizeF, Color
from aspose.imaging.imageoptions import PngOptions, CdrRasterizationOptions
# ---- Case B: CDR → PNG produces a blank image ----
with Image.load("Monthly Music - 03 March.cdr") as image:
cdr_options = CdrRasterizationOptions()
cdr_options.page_size = cast(SizeF, image.size)
cdr_options.background_color = Color.white
png_options = PngOptions()
png_options.vector_rasterization_options = cdr_options
image.save("out.png", png_options)IMAGINGPYTHONNET-532 The feasibility of iterating over SVG file content
from aspose.imaging import Image
from aspose.imaging.fileformats.svg import SvgImage
with as_of(Image.load("sample_car.svg"), SvgImage) as image:
objects = image.get_svg_objects()
findId = "path3043"
print(f"Number of entries: {len(objects)}")
for obj in objects:
if obj.get_property_value("id") == findId:
print(f"Content of entry ID: {findId}")
print(str(obj))
break
