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, ...)
-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!
