/* gerber files have different parameters to define units and how items must be plotted.

* some are for the entire file, and other can change along a file.
|
|
* In Gerber world:
|
|
* an image is the entire gerber file and its "global" parameters
|
|
* a layer (that is very different from a board layer) is just a sub set of a file that
|
|
* have specific parameters
|
|
* if a Image parameter is set more than once, only the last value is used
|
|
* Some parameters can change along a file and are not layer specific: they are stored
|
|
* in GERBER_ITEM items, when instancied.
|
|
*
|
|
* In Gerbview, to handle these parameters, there are 2 classes:
|
|
* GERBER_IMAGE : the main class containing most of parameters and data to plot a graphic layer
|
|
* Some of them can change along the file
|
|
* There is one GERBER_IMAGE per file and one graphic layer per file or GERBER_IMAGE
|
|
* Gerbview does not read and merge 2 gerber file in one graphic layer:
|
|
* I believe this is not possible due to the constraints in Image parameters.
|
|
* GERBER_LAYER : containing the subset of parameters that is layer speficic
|
|
* A GERBER_IMAGE must include one GERBER_LAYER to define all parameters to plot a file.
|
|
* But a GERBER_IMAGE can use more than one GERBER_LAYER.
