"complete" clip-types describe a complete clip, "partial" clip describes only relative changes to the previous clip. complete clips need all attributes of the tags, partial clips only attributes to identify the tag and the changed attributes. the "length"-attribute in the samples-tag is mandatory. following fields are optional on partial clips: layer, channel, samples, selection. all data outside the "laoe" field are ignored. the fileformat is identified through the laoe-tag and its attribute "fileformat". the file consists of two parts, the xml-header described below, which contains general informations, and the samples-body, which is outside the xml-part and contains all sample values, as binary streamed float-values. optional binary serialized samples in the same order than described in the XML-header... Since LAoE version 0.4.04 beta the channel-selection may optionally contain intensity-information. So the selection may be an element with separate begin- and end-tag in addition to the old data-less version. Backward-compatibility must be guaranteed!!! Here an example: ... ... Since LAoE version 0.4.05 beta the channel may optionally contain a mask.Backward-compatibility must be guaranteed!!! Here an example: ... ... ... The layer contains a new optional attribute "plotType": at the time, two different plottypes exist: sample-curve and spectrogram. ... ... Since LAoE version 0.4.08 beta the channel may optionally contain markers.Backward-compatibility must be guaranteed!!! Here an example: ... ... ... ... Since LAoE version 0.6.02 beta the channel-plotter may optionally contain the color, in hexadecimal format. Backward-compatibility must be guaranteed!!! Here an example: ... ... ...
