This dictionary contains classes that provide display parameters for rendering Array data on various display devices. The attributes described herein provide default values suggested by the data provider for display applications and are not to be interpreted as definitive for scientific purposes. Parameters relevant to scientific interpretation are found in classes described elsewhere. The Default_Display_Settings class provides parameters with default values for the display of a generic Array object on a given display device. The Default_Display_Settings_Color class provides parameters with default values for the display of a multi-banded Array object in the red, green, and blue channels of a display device. The Default_Display_Settings_Color_Movie class provides parameters settings default values for the display of an Array object containing both color bands and frames designed to be displayed consecutively on a display device capable of display video content. The Default_Display_Settings_Movie class provides parameters setting default values for the display of an Array_3D_Movie object using a software application capable of displaying video content. This section contains the simpleTypes that provide more constraints than those at the base data type level. The simpleTypes defined here build on the base data types. This is another component of the common dictionary and therefore falls within the pds namespace. The blue_channel_band attribute identifies the number of the band, along the band axis, that should be loaded, by default, into the blue channel of a display device. The first band along the band axis has band number 1. The color_display_axis attribute identifies, by name, the axis of an Array (or Array subclass) that is intended to be displayed in the color dimension of a display device. I.e., bands from this dimension will be loaded into the red, green, and blue bands of the display device. The value of this attribute must match the value of one, and only one, axis_name attribute in an Axis_Array class of the associated Array. The comment attribute is a character string expressing one or more remarks or thoughts relevant to the object. The frame_rate attribute indicates the number of still pictures (or frames) that should be displayed per unit of time in a video. Note this is NOT necessarily the same as the rate at which the images were acquired. The green_channel_band attribute identifies the number of the band, along the band axis, that should be loaded, by default, into the green channel of a display device. The first band along the band axis has band number 1. The horizontal_display_axis attribute identifies, by name, the axis of an Array (or Array subclass) that is intended to be displayed in the horizontal or "sample" dimension on a display device. The value of this attribute must match the value of one, and only one, axis_name attribute in an Axis_Array class of the associated Array. The horizontal_display_direction attribute specifies the direction across the screen of a display device that data along the horizontal axis of an Array is supposed to be displayed. The local_identifier_reference attribute provides the local_identifier of the digital object described by the referencing class (in this case, the Default_Display_Settings class). Note that a local_identifier attribute, with the same value as this local_identifier_reference, must be present within the label. The loop_back_and_forth_flag attribute specifies whether or not a movie should only be "looped" or played repeatedly in the forward direction, or whether it should be played forward followed by played in reverse, iteratively. The loop_count attribute specifies the number of times a movie should be "looped" or replayed before stopping. The loop_delay attribute specifies the amount of time to pause between "loops" or repeated playbacks of a movie. The loop_flag attribute specifies whether or not a movie object should be played repeatedly without prompting from the user. The red_channel_band attribute identifies the number of the band, along the band axis, that should be loaded, by default, into the red channel of a display device. The first band along the band axis has band number 1. The time_display_axis attribute identifies, by name, the axis of an Array (or Array subclass), the bands of which are intended to be displayed sequentially in time on a display device. The frame_rate attribute, if present, provides the rate at which these bands are to be displayed. The vertical_display_axis attribute identifies, by name, the axis of an Array (or Array subclass) that is intended to be displayed in the vertical or "line" dimension on a display device. The value of this attribute must match the value of one, and only one, axis_name attribute in an Axis_Array class of the associated Array. The vertical_display_direction attribute specifies the direction along the screen of a display device that data along the vertical axis of an Array is supposed to be displayed.
