Question: What is the recommended approach for displaying rotated text using bitmap fonts in a Transparent end-to-end Packet-switched Streaming Service (PSS) to ensure readability?
Option 1: Rotate text at any desired angle to enhance visual appeal.
Option 2: Use font sizes that adapt to the rotation angle to maintain clarity.
Option 3: Convert all bitmap fonts to vector fonts before applying rotation.
Option 4: Limit rotation to multiples of 90 degrees for bitmap fonts.
Explanation: This approach is recommended because rotating bitmap fonts at arbitrary angles can lead to unreadable text due to pixelation and distortion. By limiting rotations to multiples of 90 degrees, content creators can ensure that the text remains legible, as this typically involves straightforward flipping or mirroring of the font's pixel grid without introducing distortions that compromise readability. This is particularly important in streaming services where maintaining viewer experience is crucial.
