HPGL Plotter (PLT) technical notes
Importing a PLT file
• Corel programs support versions 1 and 2 of PLT file formats although some features of version 2 are not supported.
• You can import images larger than the Corel program’s maximum page size by enabling the Scale option in the HPGL options dialog
box, which lets you resize the imported image.
• The curve resolution factor can be set to a value between 0.0001 and 1.0 inch. The value can be very precise; up to eight decimal places
are accepted. A setting of 0.0001 results in the highest resolution, but it also greatly increases file size. A curve resolution of 0.004 inch
is recommended.
• The PLT file format does not contain color information. Instead, the various objects in a PLT file have certain pen numbers associated
with them. When imported into a Corel program, each pen number is assigned a specific color. You can specify the color assigned to a
particular pen, so that you can match the original colors of the graphic.
• The Pen selection list contains 256 pens, although not all of the pens may be assigned. You can change the color assignments by
choosing the pen and then choosing a new color for that pen from the Pen color list box. Choosing Custom colors brings up a color
definition dialog box that allows you to define a custom color according to RGB values.
• You can change the pen width assignments by choosing the pen and then choosing a new width for that pen from the Pen width list
box.
• You can change the pen velocity by choosing the pen and then choosing a new velocity for that pen from the Pen velocity list box. This
is useful only for exporting PLT files.
• You can set a defined pen to the Unused option. You can also reset the current Pen Library pen settings to the previously saved settings.
• Corel programs support numerous dotted, dashed, and solid line types of the PLT file format. The pattern number of a line in a PLT file is
translated to a line type pattern.
• If the PLT file contains a font that is not on the user’s computer, the PANOSE font matching dialog box lets the user replace the font
with an available one.
Exporting a PLT file
• In CorelDRAW X8, you now have the option of setting the Plotter origin to Top left.
• Only the outlines of objects are exported to the PLT file format.
• Dotted lines, dashed lines, and arrowheads are mapped to standard line types of the PLT file format.
• Bézier curves are converted to line segments.
• Outline thickness and calligraphic settings are lost.
• Outline colors are limited to eight: black, blue, red, green, magenta, yellow, cyan, and brown.
Portable Network Graphics (PNG)
The Portable Network Graphics (PNG) file format is an excellent file format for lossless, portable, and well-compressed storage of bitmaps.
It takes up a minimum amount of disk space and can be easily read and exchanged between computers. The Portable Network Graphics
format provides a replacement for the GIF format and can also replace many common uses of the TIFF format.
