| [RESOUCE_BLOCK_SIGNATURE](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/resouce_block_signature) | The resource signature. |
| [jpeg_options](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/jpeg_options) | Gets or sets the JPEG options. Suitable when thumbnail resource is saved into JPEG file format only. This option has no effect when RAW format is defined. |
| [width](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/width) | Gets or sets the width of thumbnail in pixels. |
| [height](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/height) | Gets or sets the height of thumbnail in pixels. |
| [width_bytes](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/width_bytes) | Gets the row width in bytes. |
| [total_size](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/total_size) | Gets the total data size. |
| [size_after_compression](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/size_after_compression) | Gets or sets the size after compression. Used for consistency check. |
| [bits_pixel](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/bits_pixel) | Gets or sets the bits pixel. |
| [planes_count](/cad/python-net/aspose.cad.fileformats.psd.resources/thumbnail4resource/planes_count) | Gets or sets the planes count. |
