Updated the HTML command reference files to refer to magic version 8.3, since all of the title images still had 8.2, and the title text still said 7.3 or 7.4, having not been updated for a long time.

<H2>erase</H2>
<HR>
Erase paint from the layout inside the bounds of the cursor box.
<HR>
<H3>Shortcuts:</H3>
<BLOCKQUOTE>
Key macro <B>Control-D</B> implements the command "<B>erase $</B>",
which indicates to erase all paint and labels in the cursor box. <BR>
Key <B>e</B> typed while the cursor is in a layer box in the GUI toolbar
implements the command "<B>erase</B> <I>layer</I>", passing the layer
type in the toolbar. <BR>
Key Shift plus Mouse button 2 implements the command
<B>erase cursor</B> when using the "box tool" in a layout
window. <BR>
</BLOCKQUOTE>
<H3>Usage:</H3>
<BLOCKQUOTE>
Extended the "paint" and "erase" commands to accept an option "pick x y" which acts like "cursor", but operates on a database coordinate instead of a pointer coordinate. Made a few other corrections to the command logging code so that it produces valid output when the log file is sourced.

<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>erase</B> command erases paint inside the cursor box in the
current edit cell. Without arguments, everything inside the box
is erased. With argument <I>layers</I>, only the indicated layers
are erased. <P>
Note that some layer types, such as DRC paint, cannot be erased.
Feedback areas are not considered paint and should be erased
using the <B>feedback clear</B> command. <P>
The option "<B>erase cursor</B>" picks the layers at the position
of the (X11) cursor and erases these from the area of the cursor
Added a new command option "contact erase". This provides a way to remove contact cuts from a layout without affecting the surrounding metals, which is something that the "erase" command does not do.

2023-07-08 23:34:00 +02:00
The option "<B>erase pick</B> <I>x y</I>" works like "<B>erase
cursor</B>", but the type of material to erase is selected from
the given position in layout coordinates instead of a pointer
position. <P>
Added a new command option "contact erase". This provides a way to remove contact cuts from a layout without affecting the surrounding metals, which is something that the "erase" command does not do.
2022-04-07 17:10:24 +02:00
Note that when applied to contact types, "<B>erase</B>" will erase
the entire contact, including the top and bottom metal types
comprising the contact. To remove the contact cuts without affecting
the surrounding material, use the "<B>contact erase</B>" command. <P>

Updated all of the documentation by copying back from the website. The website documentation now points to these contents in a clone of the repository on opencircuitdesign.com, so all future edits of the command-line documentation will be made directly to the git repository. Also: Changed the precision of box values printed in microns from 2 to 3 digits after the decimal place, so that 5 nanometer grids do not get values clipped in the output.
