Feature: Append an inline picture in its own paragraph

In order add an image to a document

As a developer using python-docx

I need a way to add a picture in its own paragraph

Scenario: Add a picture at native size

Given a blank document

When I add a picture specifying only the image file

Then the document contains the inline picture

And the picture has its native width and height

Scenario: Add a picture specifying both width and height

Given a blank document

When I add a picture specifying 1.75" width and 2.5" height

Then picture.width is 1.75 inches

And picture.height is 2.5 inches

Scenario: Add a picture specifying only width

Given a blank document

When I add a picture specifying a width of 1.5 inches

Then picture.height is 2.14 inches

Scenario: Add a picture specifying only height

Given a blank document

When I add a picture specifying a height of 1.5 inches

Then picture.width is 1.05 inches
