This structure is used to define the options of the L_CaptureArea function.

Comments

The area of the bitmap outside the user-defined region will be filled with the pattern defined by nFillPattern, crFillForeColor, and crFillBackColor.

The zoom factor can be obtained from the flags as follows:

zoom_factor = ((uFlags & CAPTURE_AREA_ZOOM_BY15X) >> 12) 

The flag can be obtained from the zoom factor as follows:

Flag = (zoom_factor)<< 12 

nInfoWidth, nInfoTop, nInfoWidth and nInfoHeight are ignored if CAPTURE_AREA_SHOW_INFOWINDOW is not set.

CAPTURE_AREA_SHOW_INFOWINDOW and CAPTURE_AREA_SHOW_CAPTURESIZE are not mutually exclusive. If both flags are set, you will have both an info window and the size of the captured area. Likewise, if CAPTURE_AREA_SHOW_INFOWINDOW and CAPTURE_AREA_SHOW_CURSORPOS are set, you will have both an info window and the position of the cursor.

After the initial placement of the info window, the window will be moved to another corner of the screen whenever the mouse cursor becomes near the info window. This way, the user will not be disturbed during the selection of the area he wants, and he will be able to see a zoomed image for the current cursor position. The info window will look like this:
