convertToHimetrics – PDK Tool

Usage

Simply go to the folder where the script is located and run the convertToHimetric.py script in your command line from there.
In the following code FrizingPDK/Tools is our sample directory we change directory (cd command) to; in your case change directory to wherever you downloaded the PDK to.

    % cd FrizingPDK/Tools
    % python convertToHimetrics.py KIND PIXELS

KIND and PIXELS are the arguments of this script:
KIND defines what kind of conversion you want calculated (bounds, offset or leg)
PIXELS is the x by y measurement, written n x n where n is a number in pixels

Simple Example

We measure 100 x 40 pixels in our drawing application

    % python convertToHimetrics.py bounds 100 x 40

converts it to himetric and returns a bounds tag which you can just copy into the partdescription.xml file.

Full Reference

The convertToHimetric.py is a simple script to convert pixel measurements into highmetric. For use in the Fritzing partdescription.xml files. It takes a pixel vector e.g. 5x12 and converts this into a <tag> which can be placed in your partdescription.xml file directly.

Usage:

	python convertToHimetrics.py KIND PIXELS

Arguments:

KIND

the kind of conversion which is performed and the kind of tag which is returned. Possible kinds are:

bounds

creates <bounds> tag.

Use 100% view pixels as measurement

offset

creates <gridOffset> tag.

Use 400% view pixels as measurement

leg

creates <point> tag which can be used as a child of <connector>.

Use 400% view pixels as measurement

hibounds

creates <bounds> tag.

Use 400% view pixels as measurement

pixeloffset

creates <gridOffset> tag.

Use 100% view pixels as measurement

pixelleg

creates <point> tag which can be used as a child of <connector>.

Use 100% view pixels as measurement

hioffset

equal to 'offset'

hileg

equal to 'leg'

PIXELS

the size or offset measured in pixels.

The pattern for this must follow: 'n x n', where

n

is the number in pixels.
It should be an integer, but can also be negative (e.g. -40)

Example:

You want to create a <gridOffset> tag. In the 400% view of your drawing application you are measuring a 50 x 349 square between the top-left corner of your 400% part and the grid point that should be the grid origin (where x="0" and y="0"). Then use the following command:

	python convertToHimetrics.py offset 50 x 349

it returns

	<gridOffset x="318" y="2216" units="himetric"/>

which you can paste into your partdescription.xml file.
