QET_ElementScaler

QET_ElementScaler is a commandline-tool to scale QElectroTech-Elements with constant factor(s) and save the changed data to a renamed file. With the optional parameter "-o" or "--stdout" the changed data is written to stdout and no new file is created.

As a gimmick, you can convert QET-Elements to SVG! (see options below)

It compiles with C++17 activated on Debian/GNU Linux (stable and unstable), ReactOS (0.4.15-dev), win, ...
The ReactOS-Build can also be used with Win in a cmd-window.

QET_ElementScaler can process one file at a time. If you want to edit all files in a directory, you need to call QET_ElementScaler from a batch-, cmd- or shell-script-file such as the ones available here.

You do not want to (or can't) compile the program yourself? Download the executable file suitable for your operating system from the releases-page and use that.

Hint:
Get familiar with the command line before using this software. General support for using the command line for the various systems cannot be provided here.

usage:
QET_ElementScaler [options] <file>
(as used in Batch-File "scale.cmd" and shell-script "scale.sh")


available options:

   -i | --stdin     input-data is read from stdin, a given filename is
                    ignored and scaled element will be written to stdout
   -o | --stdout    output will be written to stdout
   -F VALUE         or
   --factor VALUE   factor for both directions (x, y, rx, height, ...)
   -x VALUE         or
   --factorx VALUE  factor for x-values (x, rx, width, ...)
   -y VALUE         or
   --factory VALUE  factor for y-values (y, ry, height, ...)
   -X VALUE         or
   --movex VALUE    move in x-direction after scaling
   -Y VALUE         or
   --movey VALUE    move in y-direction after scaling
   -f FILENAME      or
   --file FILENAME  the file that will be used 
   -d VALUE         or
   --decimals VALUE number of decimals for float-values in output
   -h | --help      show this help

there are also some "long-opt"-only options:

  "--toSVG"              creates data for a Scalable-Vector-Graphic
                         instead of a QElectroTech-element
  "--RemoveAllTerminals" removes all terminals from the element
                         (useful for front-views or "thumbnails")
  "--FlipHorizontal"     flips all graphical elements horizontally
                         (useful during creation of elements) 
  "--FlipVertical"       flips all graphical elements vertically
                         (useful during creation of elements) 
  "--Rot90"              rotate element clockwise by 90 degree
                         (useful during creation of elements)
  "--OverwriteOriginal"  the original file is replaced by scaled one
                         (CAUTION: Be careful with this option!) 

examples to use data from stdin:
QET_ElementScaler -i -F 2.0 < ElementToScale.elmt > ScaledElement.elmt

or use a pipe like this
cat ElementToScale.elmt | QET_ElementScaler -i -F 2.0 | OtherSoftwareBinary

another example:
QET_ElementScaler -i -x 2 -y 3 < ElementToScale.elmt > ScaledElement.elmt


QET_ElementScaler uses Arseny Kapoulkine's "pugixml" (https://github.com/zeux/pugixml) to handle the content of the Element-File. Thank you, Arseny!

Many thanks, of course, to the developers and contributors of QElectroTech - a free software to create electric diagrams. (https://qelectrotech.org)
