Remarks
Metafiles (Wmf or Emf) is an uncompressed image format and sometimes requires to much RAM to hold and process document. This option allows to convert all metafile images to Png on document loading. Please note - conversion vector graphics to raster decreases quality of the images.
Examples
Shows how to convert WMF/EMF to PNG during loading document.
doc = aw.Document()
shape = aw.drawing.Shape(doc, aw.drawing.ShapeType.IMAGE)
shape.image_data.set_image(IMAGE_DIR + 'Windows MetaFile.wmf')
shape.width = 100
shape.height = 100
doc.first_section.body.first_paragraph.append_child(shape)
doc.save(ARTIFACTS_DIR + 'Image.convert_metafiles_to_png.docx')
shape = doc.get_child(aw.NodeType.SHAPE, 0, True).as_shape()
self.verify_image_in_shape(1600, 1600, aw.drawing.ImageType.WMF, shape)
load_options = aw.loading.LoadOptions()
load_options.convert_metafiles_to_png = True
doc = aw.Document(ARTIFACTS_DIR + 'Image.convert_metafiles_to_png.docx', load_options)
shape = doc.get_child(aw.NodeType.SHAPE, 0, True).as_shape()
self.verify_image_in_shape(1666, 1666, aw.drawing.ImageType.PNG, shape)
