ADOBE PHOTOSHOP ELEMENTS 4.0 213 User Guide Patchwork The Patchwork filter breaks up an image into squares filled with the predominant color in different areas of the image. The filter randomly reduces or increases the tile depth to replicate the highlights and shadows. You can set the square size and relief. Stained Glass The Stained Glass filter repaints an image as single-colored adjacent cells outlined in the foreground color. You can set the cell size, border thickness, and light intensity. Texturizer The Texturizer filter allows you to simulate different texture types or select a file to use as a texture. Texture options make images appear as if they are painted onto textures such as canvas and brick or viewed through glass blocks. Video filters De-Interlace The De-Interlace filter smooths moving images captured on video by removing either the odd or even interlaced lines in a video image. You can choose to replace the discarded lines by duplication or interpolation. NTSC Colors The NTSC Colors filter restricts the gamut of colors to those acceptable for television reproduction to prevent oversaturated colors from bleeding across television scan lines. Other filters High Pass The High Pass filter retains edge details in the specified radius where sharp color transitions occur and suppresses the rest of the image. (A radius of 0.1 pixel keeps only edge pixels.) The filter removes low-frequency detail in an image and has an effect opposite to that of the Gaussian Blur filter. You can use the High Pass filter to extract line art and large black-and-white areas from scanned images. To do so, apply the filter before using the Filter > Adjustments > Threshold command or converting the image to Bitmap mode. Maximum and Minimum The Maximum and Minimum filters look at individual pixels in a selection, like the Median filter. Within a specified radius, the Maximum and Minimum filters replace the current pixel's brightness value with the highest or lowest brightness value of the surrounding pixels. The Maximum filter has the effect of applying a choke-spreading out white areas and choking in black areas. The Minimum filter has the effect of applying a spread-spreading out black areas and shrinking white areas.
