Measure number of black pixels on image

  Measure image skew within a ± 45° range to the nearest horizontal or vertical axis.
  Skew is measured using text and line objects
  Measurement resolution ± 0.1°
  Outputs angle (in degrees) and confidence (in %)

  Measure rectangular area containing ALL image black pixels

  Measure number of pixels in each of image columns
  Output is an Integer Array
  Not applicable to color and grayscale images

  Measure number of pixels in each of image rows
  Output is an Integer Array
  Not applicable to color and grayscale images

  Identify objects groups of mutually touching black pixels
  Measure and read characteristic of each object (one at a time)
Number of black pixels
Rectangle encompassing all object pixels
Number of intervals groups of horizontally adjacent pixels
  Not applicable to color and grayscale images

Create new image containing only the pixels of the specified object
  Not applicable to color and grayscale images

  Identify horizontal and/or vertical line. Lines filtered on basis of:
Minimum length in pixels
Maximum line break size in pixels
Maximum skew angle (maximum value is 5.0°)
Amount of line curvature
  Measure and read characteristic of each line (one at a time)
Rectangle encompassing all line pixel
Location of line ends
Line angle
Line thickness
Line direction (vertical or horizontal)

Morphological Operations

Dilate or fatten image objects specifying
  Number of pixels
  Direction: Horizontal, vertical, diagonal or any combination
  Not applicable to color and grayscale images

Erode or trim image object specifying
  Number of pixels
  Direction:Horizontal, vertical, diagonal or any combination
  Not applicable to color and grayscale images

For all logical operations:
  One image or zone is used as source and destination, another image or zone is used as second source.
  Alignment of the upper left corner of the second sources on the destination image is specified.
  Only pixels present in both sources participate in operation

Sets destination pixel to white if any of source pixels is white

Sets destination pixel to black if any of source pixels is black

Sets destination pixel to black if source pixels are of different color

Sets destination pixel to color of second source pixels

Separate X and Y scaling factors may be specified. Scaling down algorithms:
  Skip extra lines
  Merge lines setting pixel black if black in any line
  Merge lines setting pixel white if black in any line
  Merge lines setting pixel black if number of pixels in merged lines is above specified threshold (in percent)
Scaling up increases the resolution of the image.
Scaling does not change the physical size of the image, for that purpose see Repair Resize.

Produces separate Windows DIB object representing the scaled image. Parameters that may be specified:
  Separate X and Y axis scaling factors
  Bitmap contrast (0 to 256)
  Bitmap brightness (0 to 256)
  Scaling down algorithms:
Best visual quality
Maximum scaling speed
