def selective_erase_rectangle(top = 0, left = 0, bottom = @screen.height - 1, right = @screen.width - 1) #

Erases all erasable characters from a specified rectangular area in page memory. The select character protection attribute (DECSCA) control function defines whether or not DECSERA can erase characters.

When an area is erased, DECSERA replaces character positions with the space character (2/0). DECSERA does not change:

  • Visual attributes set by the select graphic rendition (SGR) function
  • Protection attributes set by DECSCA
  • Line attributes

The coordinates of the rectangular area are affected by the setting of origin mode (DECOM). Method is not affected by the page margins.

CSI Pt; Pl; Pb; Pr$ {
  Selective Erase Rectangular Area (DECSERA), VT400 and up.
    Pt; Pl; Pb; Pr denotes the rectangle.
