scan lines การใช้

• The value returned is the actual scan line divided by 2.
• This number of scan lines is controlled with the VSCROL register.
• ANTIC retrieves data and updates CTIA / GTIA every scan line.
• Normally a character cell has 8 scan lines, 0-7.
• Also, a nominal scan line has three targets it must cover.
• Finally, identical adjacent scan lines are efficiently encoded by simply skipping them.
• This register specifies the distance of the Vertical fine scrolling in scan lines.
• This register tracks the scan line currently being generated.
• Placement at the top or bottom of the disk gives horizontal scan lines.
• VEIL-II uses scan lines 34 to 258.
• They share the process of rendering images using Scan Line Interleave, or SLI.
• ANTIC adds one to this value and displays the resulting number of scan lines.
• The maximum value range covers fine scrolling 16 scan lines from 0 to 15.
• Ancillary data can be located in non-picture portions of horizontal scan lines.
• PCX image data is stored in rows or scan lines in top-down order.
• Normal CGA has only 200 scan lines.
• Vertical Fine Scrolling for Map modes only one scan line tall is logically not practical.
• The position of a framing mask before the Nipkow disk determines the scan line orientation.
• The vibration was converted to raster scan lines and sent to the nearby CRT display.
• In NTSC, 4-bit symbols are encoded in groups of 8 scan lines.
