2.2.6 embodiment of Photoshop projection extension parameters in Flash Filter

Drag the slider Of The Photoshop extension item, and pull the numeric box of the flash intensity item, you will find that they do the same thing, that is, control the intensity of the Shadow extension, the larger the value, the higher the intensity, the more opaque the shadow color, the larger the valid area of the shadow.

However, I am quite confused about their value ranges. Photoshop ranges from 0% ~ 100%, while Flash is 0% ~ 25500%, and their variation is a little unpredictable. In Photoshop, drag the slider to the right at a constant speed to increase the projection speed evenly (in fact, due to the influence of decimal pixels, sometimes the projection size is between 5% and ~ Within the range of 10% (the specific range value is also related to the next Attribute-size), there is almost no change, resulting in a slight abrupt transition of projection amplification ). Flash changes are uneven. At the starting position of 100%, the projection speed became faster, but the speed showed a sharp drop. After 500%, it takes a long distance to increase the projection size. As for the 1000% and later versions, there were no obvious changes after a long drag. However, I had to try to directly enter a large number (such as 10000%) to see a slight amplification of the projection.

Considering that the correspondence between the extension and the intensity is complex, and without modifying this parameter, the performance of Photoshop and flash is different, so we will not discuss it here.
