Technical note

What changes when you convert CZI to GBR

CZI is made of pixels and GBR stores geometry, so the conversion traces the image into real lines, arcs and polylines. The result is editable in CAD: entities can be selected, snapped to and measured, rather than a bitmap wrapped inside a GBR container, which is what a viewer or a lightweight converter usually produces. It is still derived geometry, so expect contours rather than a structured drawing. Dimensions, blocks and meaningful layer names were never in the CZI to begin with. A CZI file has a pixel count and a DPI value, and no real-world size at all. GBR is a drawing where one unit means one millimetre or one inch, so the conversion has to assign a scale. Set the DPI before the run rather than resizing afterwards, then measure one feature of known length in the output and scale the drawing once to match it. Everything downstream, from dimensioning to cutting, rests on that single check.

FAQ

CZI to GBR Conversion

What are CZI files?

CZI (Carl Zeiss Image) is the native image format of ZEISS ZEN microscopy software. It stores multidimensional acquisitions with channels, z-stacks, time series and mosaic tiles, together with the full set of instrument and acquisition metadata.

What are GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.
