anchor.diff:  
   If the resolved height of the image is less than or equal to 1.5 times the line height, the image won't disrupt the line height and is centered vertically in the line.
   This is done to maximize the use of available space.
  -Once the resolved height exceeds this amount, the height of the line is increased (by increasing the font size of the invisible placeholder text) to accomodate the image.
  +Once the resolved height exceeds this amount, the height of the line is increased (by increasing the font size of the invisible placeholder text) to accommodate the image.
   In this case, the surrounding text will be aligned to the bottom of the image.
   If the image height exceeds the height of the page, the image will be scaled down to fit on a single page (this may cause the image to advance to the subsequent page).
   
  
positive.code: |If you don't specify one of the aforementioned width settings, the intrinsic width of the image is used (the px value is multiplied by 75% to convert to pt, assuming canvas is 96 dpi) unless the width exceeds the content area width, in which case the image is scaled down to the content area width.
  |===
  
  The image is always sized according to the explicit or intrinsic width and its height is scaled proporationally.
  The height of the image is ignored by the PDF converter unless the height of the image exceeds the content height of the page.
  In this case, the image is scaled down to fit on a single page.
