Value
Turn on to force the bicubic and polyphase algorithms to share the
same horizontal and vertical scaling coefficient data.
Choose the number of vertical filter taps for the bicubic and
polyphase algorithms.
Choose the number of vertical filter phases for the bicubic and
polyphase algorithms.
Choose the number of horizontal filter taps for the bicubic and
polyphase algorithms.
Choose the number of horizontal filter phases for the bicubic and
polyphase algorithms.
Turn on to force the algorithm to use signed vertical coefficient
data.
Choose the number of integer bits for each vertical coefficient.
Choose the number of fraction bits for each vertical coefficient.
Turn on to force the algorithm to use signed horizontal coefficient
data.
Choose the number of integer bits for each horizontal coefficient.
Choose the number of fraction bits for each horizontal coefficient.
Choose the number of fractional bits you want to preserve
between the horizontal and vertical filtering for the bicubic and
polyphase algorithms.
Turn on to update the scaler coefficient data at run time.
Choose the number of banks of vertical filter coefficients for
polyphase algorithms.
Choose the function used to generate the vertical scaling
coefficients. Choose either one for the pre-defined Lanczos
functions or choose Custom to use the coefficients saved in a
custom coefficients file.
When a custom function is selected, you can browse for a
comma-separated value file containing custom coefficients. Key in
the path for the file that contains these custom efficients.
Choose the number of banks of horizontal filter coefficients for
polyphase algorithms.
Choose the function used to generate the horizontal scaling
coefficients. Choose either one for the pre-defined Lanczos
functions or choose Custom to use the coefficients saved in a
custom coefficients file.
