Overview |
Refer to Thumbnail Browser. |
Remarks
Indicates the dithering options that should be used when both ForceSize and MaintainAspect are True and the source image is not 24-bit. In this case, the thumbnail image is converted to 24-bit, then, combined with a "background" bitmap. Then, the resulting bitmap is returned to the thumbnail image's original bit-depth using this setting.
