<p><b>New page</b></p><div>Instructions on how to take a regular rasterized image (eg. JPG, BMP, PNG etc.) and convert it into a vectorized format compatible with the MLA150. This produces a much smaller file than a raw BMP image, because large-area polygons are created, as opposed to defining each pixel across a 150mm wafer (which hits the RAM limit on the computer). <br />
<br />
In this example, we convert the image into simple 1-bit black-and-white image using the free software [https://www.gimp.org GIMP], and then convert to a Vector format using the free software [https://inkscape.org InkScape]. Then we correct the scale and convert to GDS using the free software [https://www.klayout.de KLayout].<br />
<br />
==== Procedure ====<br />
'''[https://www.gimp.org/ GIMP]:''' (can also do in another image editor, such as Paint.exe)<br />
<br />
open the Image (JPG, PNG, BMP etc.), <br />
<br />
Image > Mode > Indexed > 1-bit<br />
<br />
Optional: Dither to handle grey values, haven't tried this.<br />
<br />
Can edit by painting etc.<br />
<br />
Save as any JPG, PNG, BMP format<br />
<br />
'''[https://inkscape.org/ Inkscape]:'''<br />
<br />
Open the Image file, default options<br />
<br />
Click on the Image with the Arrow tool, to select it.<br />
<br />
Path > Trace Bitmap (options affect curves/resolution)<br />
<br />
- Use the “Update” button to show a Preview of the Path that will be created.<br />
<br />
- Options: Trace BitMap > Single-Scan > AutoTrace (dropdown menu). <br />
<br />
- [OK] to create the Path, then Close the “Trace Bitmap” window.<br />
<br />
- Creates a new Path object that outlines the image<br />
<br />
Use the Arrow select tool to select the Image<br />
<br />
- bottom bar shows what object is selected<br />
<br />
- Option/Alt-Click to select obscured objects<br />
<br />
- Make sure PATH is Not selected<br />
<br />
Delete the Image. File should have only the Path object in it.<br />
<br />
File > Save a Copy… > DXF (Autocad R14) <br />
<br />
