#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

#  The two-page PDF used in this example is available at markdown_options.pdf

#  Now change the options:

#  pageBreaks: "comment" (the default) separates pages with <!-- page N -->,
#  "rule" separates them with a horizontal rule (---), and "none" runs the pages together.
json.UpdateString("pageBreaks","rule")

#  images: "placeholder" (the default) marks where each image sits with ![image](page-1-image-1);
#  "none" leaves images out.
json.UpdateString("images","none")

#  tables: "ruled" (the default) converts tables that have drawn cell borders into Markdown tables;
#  "none" returns their cells as plain text.
json.UpdateString("tables","none")

#  emphasis: false leaves out the ** and * markers for bold and italic.
json.UpdateBool("emphasis",False)

#  maxHeadingLevel: inferred headings deeper than this level are folded into this level.
#  The PDF has three heading levels; with maxHeadingLevel 2 the third level becomes ##.
json.UpdateInt("maxHeadingLevel",2)
