RGB2RTL

Use this to convert. rgb files to. rtl files. The rgb2rtl program is used by the Screen Dump button on the Graphics toolbar when dumping screens to an HPGL2 type plotter.

Usage:

rgb2rtl [-options] image.rgb

<> indicates a mandatory switch.
[ ] indicates an optional switch

Where:

Option

Description

[-options}

The [-options] for this executable are:

-b{red},{green},{blue}	Defines the background colour as an RGB triple (values between 0 and 255 each). This colour is mapped to white before plotting. Note that this will map ALL occurrences of this colour to white. For example, to map a black background to white use -b0,0,0.
-d{dots_per_inch}	Required only with the -s option, this defines the resolution of the image in dots per inch. The default is 300 dpi. In general, use the default for a DesignJet 650C and use 360 dpi for a Calcomp Techjet.
-g{gamma}	Defines the gamma warping factor to be applied to the image. A gamma value of 1.0 (the default) will produce an image where the pixel values are unmodified. A gamma of less than 1.0 will produce an exponentially lighter image. A gamma or greater than 1.0 will produce an exponentially darker image.
-i{width}x{height}	Defines the output dimensions of the image. Both width and height are measured in 1/720th of an inch (i.e. a 1"x1" image would have the dimensions 720x720)
-o{out_file}	Defines the file to which to write the output. If this option is undefined, then the output will be written to standard output.
-p{standard_page_size}	Defines the output dimensions of the image based on standard page sizes. This is equivalent to using the -i option with a width and height that will fit the image onto the page. Supported page sizes are : Metric ISO : A0... A10, B0... B10, C0... C7 American ANSI : A, B, C, D, E, F, or E1 US standards : letter, legal, ledger, executive.
-q	Quiet mode. No progress information is printed.
-s{factor}	Isotropically scale the image by the factor (ie. -s2 would produce an image twice its default size).
-w{width}	Defines the output width of the image (i.e. across page). The image is then scaled isotropically. The width is measured in 1/720th of an inch.
-DJ36	Isotropically scale the image so that the image fits exactly onto the 36" wide continuous feed roll of a DesignJet 650C plotter. This option is equivalent to using -w25920.

image.rbg

The image can be scaled to the required output size, up to the physical limits of the output device (plotter). The default size is 300 dpi (dots per inch), with each pixel being represented by a single dot.
