Description

Specifies the color of the pixels within the current ClipRect.

Read Pixels to learn the color on the drawing surface at a specific pixel position within the current clipping region. If the position is outside the clipping rectangle, reading the value of Pixels returns -1.

Write Pixels to change the color of individual pixels on the drawing surface. Use Pixels for detailed effects on an image. Pixels may also be used to determine the color that should be used for the FillRect method.

Not every device context supports the Pixels property. Reading the Pixels property for such a device context returns a value of -1. Setting the Pixels property for such a device context does nothing.
