**Summary:** Defines the LayerMaskDataShort class which contains information about the mask data in the PSD file layer<br/>            when the layer has only raster or vector mask but not both. Otherwise, a [LayerMaskDataFull](/psd/python-net/aspose.psd.fileformats.psd.layers/layermaskdatafull/) is used.<br/>            If the layer has only a raster mask the ImageData contains the raster mask data bytes.<br/>            If the layer has only a vector mask the ImageData contains the vector mask rasterized (cached) data bytes.<br/>            The [LayerMaskData.image_data](/psd/python-net/aspose.psd.fileformats.psd.layers/layermaskdata/) bytes length should be equal Width * Height of [LayerMaskData.mask_rectangle](/psd/python-net/aspose.psd.fileformats.psd.layers/layermaskdata/) properties.
