EmbossThis effect sharpens the edges of objects in the image and suppresses colors. The effect also highlights the edges from a specified angle. The layer's quality setting influences the Emboss effect by controlling the Relief setting. Relief is calculated at the subpixel level in Best quality and rounded off to the pixel level in Draft quality. The Direction option specifies the apparent direction from which the highlight source is shining, in degrees. A setting of 45 degrees causes the shadow to be cast from the northeast direction. Relief specifies the apparent height of the embossing, in pixels. The Relief setting actually controls the maximum width of highlighted edges. Contrast specifies the sharpness of the image content's edges. At lower settings, only distinct edges show the effect. As you increase the setting, the highlight becomes more extreme. |
