This dialog box controls the 3x3 or 5x5 FIR (Finite Impulse Response) filter coefficients used by the Renforcer / Enhance command (Nouvelle image / New image menu). As you change the filter coefficients, The Panorama Factory shows you the effect interactively within the preview rectangle.
Noyau du filtre / Filter kernel
The 3x3 or 5x5 convolution kernel coefficients.
Type de filtre / Filter type
3x3 3x3 FIR filter.
5x5 5x5 FIR filter.
Accentuation / Sharpen 3x3 sharpening filter. This filter is generated automatically from its center coefficient. You can also use the slider to control the center value.
Forme du filtre / Filter shape
Symétrie horizontale / Horizontally symmetric
Symétrie verticale / Vertically symmetric
Symétrie radiale / Circularly symmetric
Constrains the filter to have the specified symmetry.
Séparable / Separable
Constrains the filter be separable. A separable filter can be
applied in separate horizontal and vertical passes. This has the potential of
improving filtering speed (although The Panorama Factory currently does not
take advantage of this).
Normaliser / Normalize
Normalizes the filter coefficients so that the filter neither
brightens nor darkens the image (on average). Selecting this option causes The
Panorama Factory to divide each filter coefficient by the sum of all
coefficients when the filter is applied.

that apply to the current tool dialog box.
Enregistrer les réglages dans un profil... / Save settings to a profile...
Select this button to activate the Enregistrer les réglages dans un profil / Save settings to a profile dialog box. You can save the current
settings to an existing profile or create a new profile to hold the settings.
