|
|
* BUGS
|
|
*
|
|
* Support PICTYPE_BITMAP and PICTYPE_ICON, altough only bitmaps very well..
|
|
* Lots of methods are just stubs.
|
|
*
|
|
*
|
|
* NOTES (or things that msdn doesn't tell you)
|
|
*
|
|
* The width and height properties are returned in HIMETRIC units (0.01mm)
|
|
* IPicture::Render also uses these to select a region of the src picture.
|
|
* A bitmap's size is converted into these units by using the screen resolution
|
|
* thus an 8x8 bitmap on a 96dpi screen has a size of 212x212 (8/96 * 2540).
