Examples
Shows how to specify a compression type for all images in a document that we are converting to PDF.
doc = aw.Document()
builder = aw.DocumentBuilder(doc)
builder.writeln("Jpeg image:")
builder.insert_image(IMAGE_DIR + "Logo.jpg")
builder.insert_paragraph()
builder.writeln("Png image:")
builder.insert_image(IMAGE_DIR + "Transparent background logo.png")
# Create a "PdfSaveOptions" object that we can pass to the document's "save" method
# to modify how that method converts the document to .PDF.
pdf_save_options = aw.saving.PdfSaveOptions()
# Set the "image_compression" property to "PdfImageCompression.AUTO" to use the
# "image_compression" property to control the quality of the Jpeg images that end up in the output PDF.
# Set the "image_compression" property to "PdfImageCompression.JPEG" to use the
# "image_compression" property to control the quality of all images that end up in the output PDF.
pdf_save_options.image_compression = pdf_image_compression
# Set the "jpeg_quality" property to "10" to strengthen compression at the cost of image quality.
pdf_save_options.jpeg_quality = 10
doc.save(ARTIFACTS_DIR + "PdfSaveOptions.image_compression.pdf", pdf_save_options)
