NAME

XieMirror − This routine creates a flipped copy of an existing image. 

C Format

dst_photo_id = XieMirror(src_id, x_mirror, y_mirror)

C Argument Information

XiePhoto     dst_photo_id;
XiePhoto     src_id;
unsigned long  x_mirror;
unsigned long  y_mirror;

RETURN VALUES

If the source image is an unbound photomap, the routine returns the identifier of the new photomap in the dst_photo_id argument.  Otherwise, the routine returns the identifier of the photoflo to which the processing element appended. You can free the photomap using the XieFreeResource routine. 

PARAMETERS

src_idThe src_id argument specifies the source image.  If the source image is an unbound photomap, the operation is performed immediately. Otherwise, a processing element is appended to the specified photoflo with execution pending a call to the XieExecuteFlo routine. The photoflo is specified explicitly if the source image is a photoflo, or implicitly if the source images is a photomap or phototap. 

x_mirrorThe x_mirror argument specifies whether or not the source image is flipped about the x-axis. To flip about the x-axis, set the argument to True. 

y_mirrorThe y_mirror argument specifies whether or not the source image is flipped about the y-axis. To flip about the y-axis, set the argument to True. 

DESCRIPTION

This routine creates a flipped copy of an existing image.
