Properties

columnCount int
The maximum number of sprites per row in a sprite sheet. The default is 0, which indicates no maximum limit.
getter/setter pair
endTimeOffset Duration
End time in seconds, relative to the output file timeline. When end_time_offset is not specified, the sprites are generated until the end of the output file.
getter/setter pair
eventPlugin → EventPlugin?
Subclasses can override this getter to be notified of changes to protobuf fields.
no setterinherited
filePrefix String
Required. File name prefix for the generated sprite sheets.
getter/setter pair
format String
Format type. The default is jpeg.
getter/setter pair
hashCode int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo
no setteroverride
interval Duration
Starting from 0s, create sprites at regular intervals. Specify the interval value in seconds.
getter/setter pair
isFrozen bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
quality int
The quality of the generated sprite sheet. Enter a value between 1 and 100, where 1 is the lowest quality and 100 is the highest quality. The default is 100. A high quality value corresponds to a low image data compression ratio.
getter/setter pair
rowCount int
The maximum number of rows per sprite sheet. When the sprite sheet is full, a new sprite sheet is created. The default is 0, which indicates no maximum limit.
getter/setter pair
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
spriteHeightPixels int
Required. The height of sprite in pixels. Must be an even integer. To preserve the source aspect ratio, set the google.cloud.video.transcoder.v1.SpriteSheet.sprite_height_pixels field or the google.cloud.video.transcoder.v1.SpriteSheet.sprite_width_pixels field, but not both (the API will automatically calculate the missing field).
getter/setter pair
spriteWidthPixels int
Required. The width of sprite in pixels. Must be an even integer. To preserve the source aspect ratio, set the google.cloud.video.transcoder.v1.SpriteSheet.sprite_width_pixels field or the google.cloud.video.transcoder.v1.SpriteSheet.sprite_height_pixels field, but not both (the API will automatically calculate the missing field).
getter/setter pair
startTimeOffset Duration
Start time in seconds, relative to the output file timeline. Determines the first sprite to pick. The default is 0s.
getter/setter pair
totalCount int
Total number of sprites. Create the specified number of sprites distributed evenly across the timeline of the output media. The default is 100.
getter/setter pair
unknownFields → UnknownFieldSet
no setterinherited
