Graphics Tab (Terminal Setup Dialog Box)

Getting there

ReGIS

Terminal type

Select which terminal is emulated and how many shades or colors are available in ReGIS:

  • The VT240 and VT330 are monochrome graphics terminals, providing up to four shades of gray at once.
  • The VT241 and VT340 are color graphics terminals; the VT241 provides up to four different colors at once, while the VT340 provides up to 16 different colors.

    This value is independent of the settings for Terminal ID on the Emulation tab.

Graphics output cursor

Clear this option to hide the graphics output cursor.

ReGIS displays two types of graphic cursors: an input cursor and an output cursor. The input cursor appears when ReGIS is waiting for graphics input, such as a cursor position report. You can position the input cursor with the mouse or the Arrow keys. A graphics output cursor appears when ReGIS is waiting for commands from the host (or from the ReGIS command line).

Displaying the graphics output cursor can also be controlled by the ReGIS command S(C<n>). The ReGIS command option controls the style of the graphics output cursor.

Macrograph reports

Clear this option to disable macrograph reporting for security or other reasons.

A macrograph is a way to define and store a set of ReGIS commands as a single character; that is, as a graphics macro. By default, ReGIS can report the contents of a specific macrograph.

Sixel

Print mode

Select how sixel data is sent to the host or a Digital printer.

 

Select

To do this

 

 

Compress

Print an image pixel-for-pixel.

 

 

Rotate

Rotate the image 90 degrees (from portrait to landscape orientation).

If you want the actual output to print rotated, from the Print Setup dialog box, select Landscape as the Orientation option.

 

 

Expand

Print each pixel twice as wide and twice as high.

Expanded printing applies only when sending sixel data to the host (selected by the Destination), not to a PC printer.

Destination

When you print a graphics image using the ReGIS hard copy command, the image can be sent either to the host or a Digital printer.

When the graphics image is sent to the host, it is sent as a stream of sixel data. The host must be ready to accept the data; for example, by collecting it in a file.

When the image is sent to a host printer, it is printed as a bitmap image. If Bypass Windows print driver is selected from the Print Setup dialog box, a sixel data stream is sent to the printer (assuming you are printing to a Digital printer).

 

Graphics level

With this option, you can match Reflection to Digital printer capabilities, such as aspect ratio, horizontal grid size, background printing, and color printing. The sixel data string sent to the host varies based on the graphics level for details about the sixel data format.

This setting applies only when sending sixel data to the host or a Digital printer when Bypass Windows printer driver is selected from the Print Setup dialog box.

This setting also affects saving display sixels from the Save Display As dialog box.

 

Color printing

Select Color or Mono (black and white) printing.

This setting applies only when sending sixel data to the host or a Digital printer when Bypass Windows printer driver is selected from the Print Setup dialog box.

This setting also affects saving display sixels from the Save Display As dialog box.

 

Color specification

If you are printing in color, select the color coordinate system to use for color sixel printing.

This setting applies only when sending sixel data to the host or a Digital printer when Bypass Windows printer driver is selected from the Print Setup dialog box.

This setting also affects saving display sixels from the Save Display As dialog box.

Scrolling

A sixel is a vertical column of six pixels used to display graphic images. When scrolling is enabled, the sixel image begins at the current text position. A sixel image will scroll the display when the image reaches the bottom margin of the display (if it doesn't fit, the image may also scroll off the top of the display). A graphics newline character is sent immediately after the sixel dump, and the text cursor is set at the same position as the sixel cursor when you exit sixel mode.

When this option is cleared, the sixel image begins at the upper left of the display. When the image reaches the bottom margin, the display does not scroll, and additional sixel commands are ignored. Upon exiting sixel mode, the text cursor is set at the same position as when sixel mode was entered.

Tektronix

CR processing

When you select CR-LF, a linefeed character is appended to each carriage return character. This is useful when you're operating in local mode (when, from the Terminal Setup dialog box, on the Emulation tab, the Online option is cleared).

 

LF processing

When you select LF-CR, a carriage return character is appended to each linefeed character. This is useful when you're operating in local mode (when, from the Terminal Setup dialog box, on the Emulation tab, the Online option is cleared).

 

Del processing

Reflection interprets DEL characters as valid ASCII characters. To have Reflection ignore DEL characters, select Ignored.

GIN terminator

Select which character or characters act as a terminator for cursor address information.

Destructive overwrite

By default, a character typed over another one in Tektronix emulation does not erase the first one: the second character is superimposed on the first. Select this option to specify that you want a character cell blanked out before a character is drawn.

Printing

Print graphics

Select this option to print graphics along with the text when sending sixels to the host or to a Digital printer.

This setting also affects saving display sixels from the Save Display As dialog box.

Print background

Select whether to print the graphics image with or without the background color when sending sixels to the host or a Digital printer.

Clear this option to print to a printer that can print only a black and white bitmap, and no shades of gray. The colors of the screen image are inverted for printing. This makes light-colored graphics print as black images on white paper. If you're printing 16-color graphics, the resulting images may be unpredictable as a 16-color image must be converted to a 2-color (black and white) bitmap. This applies to sixels generated as well as graphics printed on Windows printers.

This setting also affects saving display sixels from the Save Display As dialog box.

Copying

VGA dithering

Select to cause bitmaps copied to the Clipboard to be dithered to standard VGA colors. This is useful for pasting graphic images into Windows applications that are not palette-aware (for example, Windows Paint).

Select the level of dithering to be applied when a 256-color image is pasted into the terminal window from the Clipboard. Because Reflection emulates a 16-color terminal, it uses an algorithm to determine exactly how colors should be mapped. The best dithering choice for an image may vary depending on the image.

 

 

Select

To produce this

 

 

Half

A pasted image that takes a middle course between the None and Full values.

 

 

Full

The most accurate color translation. However, the pasted image could have a grainy, textured appearance.

 

 

None

A pasted image with a color specified for each individual pixel. This option produces the crispest image. However, there may be no distinct color boundaries.

Note: Selecting None as the level of VGA dithering does not have the same effect as clearing the VGA dithering check box. The state of the check box controls whether the image is converted to a VGA-displayable image when it is copied if the check box is cleared, the exact image is copied (including its exact colors). This works well when pasting graphics into applications that are palette-aware (such as Photoshop).

For applications that are not palette-aware (such as Windows Paint), select this check box and pick a dithering option (explained above) that determines how Reflection processes the pixels.

Copy background

When cleared, bitmaps copied to the Clipboard are edited so that the background color is set to white, and all near-white colors are set to black. This is useful for pasting graphic images into word processing documents.
