NOTE: |
THIS FUNCTION IS NOW INHERITED DIRECTLY FROM THE PARENT LANNOTATION CLASS. |
Sets the font size of the annotation object.
Parameter | Description | |
dFontSize | The font size to set, expressed as an unscaled value relative to the container. | |
uFlags | Flags that determine which objects to process. Most of the flags apply only to container objects. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values: | |
Value | Meaning | |
0 | Process only the specified object. | |
ANNFLAG_SELECTED | [0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnContainer::GetSelectItems() and LAnnotation::SetSelected() functions. | |
ANNFLAG_NOINVALIDATE | [0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
The font size of an object is relative to its container object. The height of a font is interpreted using the container's vertical scaling factor. For example, suppose you want the font to appear as a 10-point font on your screen using the current scaling factor. You would use the following calculation, where A is the pixel height of a 10-point font, B is the value that you get from the LAnnotation::GetScalarX function, and C is the value that you get from the LAnnotation::GetScalarY function:
dFontSize = A / sqrt( B * C )
