|
||
Demonstrates
|
||
============
|
||
How to use DirectWrite’s layout API for features like ranged formatting and
|
||
hit-testing. It supports basic editing to allow interactive modification of
|
||
the displayed text and attributes. The sample shows how to:
|
||
|
||
- Assign layout-wide attributes like text alignment, reading direction, and
|
||
trimming.
|
||
- Assign ranged attributes such font weight, font size, and font family.
|
||
- Use hit-testing to map mouse coordinates to text positions and draw
|
||
selection ranges.
|
||
- Apply a transform while retaining WYSIWIG document layout.
|
||
- Load an inline image for use in layout via WIC.
|
||
- Use drawing effects and inline images with either a D2D render target or
|
||
GDI DIB.
|
||
