DiffusionTransparency Dither applies a random pattern that is usually less noticeable than Pattern dither. If you select this algorithm, specify a Dither percentage to control the amount of dithering that is applied to the image. Pattern Transparency Dither applies a halftone-like square pattern to partially transparent pixels.

Noise Transparency Dither applies a random pattern similar to the Diffusion algorithm, but without diffusing the pattern across adjacent pixels. No seams appear with the Noise algorithm. Displays a low-resolution version of the image in a browser while the full image file is downloading. Interlacing can make downloading time seem shorter and can assure viewers that downloading is in progress. However, interlacing also increases file size.

Specifies a tolerance level for shifting colors to the closest web palette equivalents and prevent the colors from dithering in a browser. A higher value shifts more colors.

Transparency makes it possible to create nonrectangular images for the web. Background transparency preserves transparent pixels in the image. This allows the background of the web page to show through the transparent areas of your image. Background matting simulates transparency by filling or blending transparent pixels with a matte color that can match the web page background.

Background matting works best if the web page background is a solid color and if you know what that color is. If an image has multiple slices, the colors in the color table may vary between slices you can link the slices first to prevent this from happening.

Reducing the number of colors often preserves image quality while reducing the file size of the image. You can add colors that were left out in building the color table. Adding a color to a dynamic table shifts the color in the palette closest to the new color. Adding a color to a fixed or Custom table adds an additional color to the palette.

If any colors are currently selected in the color table, choose Deselect All Colors from theColor Table palette menu to deselect them. The new color appears in the color table with a small white square in the lower right corner, indicating that the color is locked.

If the color table is dynamic, the original color is displayed in the upper left and the new color is displayed in the lower right. You can change a selected color in the color table to any other RGB color value. When you regenerate the optimized image, the selected color changes to the new color wherever it appears in the image. The original color appears at the upper left of the color swatch and the new color at the lower right.

The small square at the lower right of the color swatch indicates that the color is locked. Double-click the swatch for the shifted color. The original color is selected in the color picker. Click OK to restore the color. To revert all shifted colors in a color table including web-shifted colors , choose Unshift All Colors from the Color Tablepalette menu. To protect colors from dithering in a browser, you can shift the colors to their closest equivalents in the web palette.

Select a web-shifted color in the color table and click the Web Shift button in the Color Table palette. To revert all web-shifted colors in the color table, choose Unshift All Colors from the Color Table palette menu. Click the Map Transparency button in the Color Table palette. The transparency grid appears in half of each mapped color. You can lock selected colors in the color table to prevent them from being dropped when the number of colors is reduced and to prevent them from dithering in the application.

Note: Locking colors does not prevent them from dithering in a browser. A white square appears in the lower right corner of each locked color. You can delete selected colors from the color table to decrease the image file size.

When you delete a color, areas of the optimized image that previously included that color are rerendered using the closest color remaining in the palette. When you delete a color, the color table automatically changes to a Custom palette. This is because the Adaptive, Perceptual, and Selective palettes automatically add the deleted color back into the palette when you reoptimize the image—the Custom palette does not change when you reoptimize the image.

You can save color tables from optimized images to use with other images and to load color tables created in other applications. Once you load a new color table into an image, the colors in the optimized image are changed to reflect the colors in the new color table. Name the color table and choose a location where it will be saved. By default, the color table file is given the extension.

If you want to access the color table when selecting Optimization options for a GIF or PNG image, save the color table in the Optimized Colors folder inside the Photoshop application folder. Note: When you reload the table, all shifted colors will appear as full swatches and will be unlocked. Navigate to a file containing the color table you want to load—either an Adobe Color Table.

You can use the Disk Management tool to resize, create, delete and format partitions and volumes, as well as change their drive letters—all without downloading or paying for any other software. The top pane shows you a list of your volumes. The bottom pane shows a graphical representation of your disks and the volumes that exist on each disk.

If you select a volume in the top pane, the bottom pane jumps to show the disk that contains that volume. And if you select a disk or volume in the bottom pane, the top pane jumps to show the corresponding volume there, too. Note : Technically speaking, volumes and partitions are a little different. Occasionally, you may need to resize a volume. For example, you may need have a disk with one big volume and then decide you want to make it into two separate volumes. You can do that by shrinking the existing volume and then using the freed-up space to create a new volume.

Or maybe your disk used to be divided into two volumes, but you deleted one of them. You could then extend the existing volume into that newly freed-up space to make one big volume. You can only shrink a volume if it has enough free space.

You could shrink the volume by up to nearly the full 1 TB. Notice that the window shows the total size of the current volume, and the available space you have for shrinking which in the case of our empty volume is close the total size. The only option you have is how much you want to shrink the volume by—in other words the amount of unallocated space that will be left over after the shrinking.

The window also shows the total new size of the current volume after you shrink it by however much you select. You can only extend a volume if it has unallocated space to the right of it on the same disk. It also shows the total volume size and the maximum available space you have to extend the volume. You can choose whether or not to go ahead and format the partition, but you will need to format it at some point before you can use. The only real reason you might want to not format it right away is if you need to let another tool do the formatting.

An example of this would be if you were planning to install a new operating system in the new volume so that you could dual-boot your PC into different operating systems. In that case, you might want to let the new operating system format the drive during its installation. Otherwise, go ahead and format the disk, pick a file system to use, and assign a volume label. Sometimes, you might need to delete an existing volume. One good reason for this is if you no longer use the volume.

By deleting it, you return that space to the unallocated pool and then you could use it to extend an existing volume. Maybe you just want all your main hard drives grouped together or maybe you want to use a specific letter for a certain drive. Note that only letters not already assigned to volumes are available on the dropdown. If you do run into trouble, you can change the drive letter back. You can also use Disk Management to format a volume.

Using Disk Management to do this provides all the same options as the regular format tool you access through File Explorer , so whichever you want to use is up to you.

You can format a volume whether the volume has already been formatted or not. Formatting can take anywhere from a few seconds to a minute or so, depending on the size of the volume. Third-party partition managers do sometimes include more advanced features—like creating bootable disks, recovering information from damaged volumes, and the ability to extend volumes into unallocated space to the left of the volume. So, if you need any of those features, it might be worth taking a look around.
