Why convert PLT to ICO?
PLT is the usual extension for HPGL plot files, written by CAD, sign-making and cutting-plotter software when a drawing is sent to a plotter or saved for plotting. The plotter's pen movements are replayed by hp2xx to rebuild the drawing's linework, which is placed on a white page and rendered at 144 dpi.
ICO output is a 256 × 256 pixel Windows icon: the image is scaled to fit with its proportions kept, and the surrounding space is transparent.
Frequently Asked Questions
How do I convert PLT to ICO?
Drop your PLT file above and press Convert. Our servers replay the PLT's HPGL commands with hp2xx into vector EPS, turn that into a PDF with Ghostscript, and render the page as the image you chose. The result is saved as a 256 × 256 ICO icon, ready to download.
What sort of PLT files turn into a ICO here?
PLT files that hold HPGL plotter commands, as written by CAD programs, sign-making tools and vinyl-cutting software.
What happens to the pen paths in a PLT file when it becomes a ICO?
hp2xx replays the pen-down moves as vector lines, Ghostscript lays them onto a PDF page, and that page is rendered at 144 dpi into the ICO, so plotting and cutting paths appear as clean outlines.
Which part of the PLT becomes the ICO icon?
The first page of the rendered content is used for the icon, fitted inside the 256 × 256 square with its proportions kept.
What size is the ICO made from a PLT file?
The icon is 256 × 256 pixels, the largest standard Windows icon size. The image is fitted inside the square with its proportions kept and a transparent surround, stored as a PNG-compressed icon.
