The image must have +a vertical symmetry axis. \fBpgmabel\fP produces as output an image of +a cross-section of the image. + +\fBpgmabel\fP does the calculation by performing the Abel Integration +for Deconvolution of an axial-symmetrical image by solving the system +of linear equations. + +After integration, \fBpgmabel\fP weights all gray-values of one side +by the surface area of the calculated ring in square pixels divided by +4*\fIfactor\fP multiplied by the size of one pixel (\fIpixsize\fP). +With the \fB-verbose\fP option, \fBpgmabel\fP prints the weighting +factors. +.PP +Where the calculation generates a negative result, the output is black. +.PP +The computation is unstable against periodic structures with size 2 in +the vertical direction. + +.UN lbAE +.SH OPTIONS +.PP +You can abbreviate any option to its shortest unique prefix. + + + +.TP +\fB-help\fP +Prints a help message. + +.TP +\fB-axis\fP \fIaxis\fP +Position of the axis of symmetry in the image in pixels from the left +edge of the image.
