Import GIF or JPG?

by Lukas - 15 May 2009, 23:26 CEST

The online introduction discusses GIF and JPG file formats:
http://www.layouteditor.net/tutorial/fileformatraster.php5

However, I cannot open neither GIF or JPG. I have tried using the File Open menu.

I have used the most recent versions:
layout-20090512-mac-osx-cocoa-beta.tar.bz2
layout-20090512-mac-osx.tar.bz2

Any idea how to open an image?

thank you
Lukas

That is a mac specific problem, the library for the imageformat JPEG and GIF are not found, missing or not correctly load by the LayoutEditor. I will try to fix that problem with the next release.

As a work around you can convert these file to the PNG file format with any common pixel-graphic program. PNG files can be loaded by the LayoutEditor on Mac.

Thanks for reporting that problem!

The LayoutEditor™ is a program to design and edit layouts for MEMS/IC fabrication and CMOS IC design .Designing these layouts require a high precision. In IC design a sufficient resolution and a possibility of a high scaling is required. The resolution of the LayoutEditor can be set in a wide range and is normally set to 1 nano meter. A higher resolution makes no sense due to atomar structures. With this resolution the LayoutEditor can draw elements up to 4 meters. In many IC design houses this is enough for IC/MEMS which extend usually less than 0.1 meters. The productions of MEMS/IC is done in many layers. For each of these physical CAD layers a belonging layer had to exist in the drawing. Additional logical layers are required for describing/naming purpose. So a lot of layers are needed. By default the LayoutEditor is limited to 128 layers. But it can easily be adjusted, if more layers are required. IC Designs often contain a plenty of repeating structures. Essential for micro fabrication of these designs is therefor a hierarchical design. This means, that the complete repeating structure only exists once in a single cell. These cell is then referred multiple times in the main drawing.
Beside the above mems packaging mentioned IC design fundaments it is important to have sophisticated functions to handle all drawing elements. The layout handler has all required functions: all basic design functions, all angle elements, boolean operations, macros, fontgenerator, design rule checker, mems tools, supported format: GDSII, DXF, OASIS, CIF.
