wx:memory-dc%

Superclass: wx:canvas-dc%

A wx:memory-dc% object supports drawing into a bitmap. A wx:bitmap% object must be selected into a memory DC using select-object before any other method of the DC is called. The result of calling a method before a bitmap is selected into the DC is undefined.

• (make-object wx:memory-dc%) -> wx:memory-dc% object

  Creates a new memory DC.

  
  

• (make-object wx:memory-dc% old-dc) -> wx:memory-dc% object
      old-dc : wx:canvas-dc% object

  Creates a new memory DC with similar attributes (e.g., colour depth) to the given canvas DC.
