• loadimage

  Creates new raster layer and loads images in JPG, BMP, PNG, TIF, GIF formats using WindowsCodecs. Image intensity values are normalized (scaled) into 1.
  Example: s” test.png” loadimage cr

• saveimage

  Saves current raster image in JPG, BMP, PNG, TIF formats. Gray scale images for TIF and PNG formats are scaled to 0xffff and saved as 16bit integer values, other are scaled to 255 and saves as 8bit values.
  Example: s” test.png” savemage cr

• loadyml

  Creates new vector layer and loads a vector file into it. File should be in DXF or YML formats.
  Example: s” coastline.yml” loadyml cr

• saveyml

  Saves vector layer in YML format.
  Example: s” test.yml” saveyml cr

• chnglayer

  Changes current raster layer into the one with the index defined. The index should be in range (0,total_layers_number-1)
  Example: 0 chnglayer cr

• chngvec

  Changes current vector layer into the one with the index defined. The index should be in range (0,total_vectors_number-1)
  Example: 5 chngvec cr

• dellayer

  Deletes current raster layer. The following layer if presented is made the current.
  Example: dellayer drop cr

• delvec

  Deletes current vector layer. The following layer if presented is made the current.
  Example: delvec drop cr

• delcont

  Deletes a contour is closest to the coordinates defined.
  x = 10 y = 20
  Example: 10 20 delcont cr

• oval

  Creates eliptic polyline with defined width and heights and places it to a new layer or adds to a current. The centers of the figure is(0;0).
  w = 100, h = 200, flag = TRUE.
  Example: 100 200 1 oval cr

• rectangle

  Creates a rectangle with defined coordinates of the top left corner, width and height and places it to a new layer or adds to a current.
  x = 100, y = 200, w = 50, h = 50, flag = TRUE.
  Example: 100 200 50 50 1 rectangle cr

• line

  Ôdds vertices with coordinates defined to the first contour or creates new polylineand places it to a new layer or adds to a current layer. Sets defined closed flag.
  x =100, y = 200, close = TRUE, add = FALSE, flag = FALSE.
  Example: 100 200 1 0 0 line cr

• rotmove

  Rotates or moves current polygon in a current vector layer.
  angle = 45°, x = 100, y = 200.
  Example: 4.50e+001 100 200 rotmove cr

• crop

  Crops current layer by the top left corner coordinates defined, width and height. All vector layers of that raster layer are also shifts on the left top by x,y.
  x = 100, y = 200, w=50, h=50.
  Example: 100 200 50 50 crop cr

• label

  Creates test label in a point with the coordinates defined and adds it to the current vector layer or a new one.
  x = 100, y = 200, flag = TRUE.
  Example: s” the text” 100 200 1 label cr

• veccolor

  Changes a color of all polygons or text labels (depends on the flag) of currently selected vector layer. Predefined color table has 10 colors.
  color index = 7, polygon = TRUE.
  Example: 7 1 veccolor cr
