L_LTANN_API L_INT L_AnnSetDpiX(hObject, dDpiX, uFlags)
Sets the horizontal DPI (dots per inch) value that is used to translate user input, such as font size, that is expressed in physical measurements.
Handle to the annotation automation object.
The horizontal DPI value to set. Valid values are greater than or equal to 1.
If you pass 0 or a positive value less than 1, the value will default to 150. If you pass a negative value, the function will return an error.
Reserved for future use. You can pass 0.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
The DPI properties apply only to the annotation automation object. Refer to Annotation Automation Object.
Typically, if you are matching annotations to a bitmap, you can use the bitmap handle's XResolution field to set this value.
