Resolution – Resolution is the amount of dots an image has, usually measured in dots per inch. Note: It is not possible to increase color depth above the original image to improve the image’s quality. Subsampling – chooses a pixel in the center of the sample area and replaces the entire area with that color.Downsampling – looks at the averages of the colors for a given area and replaces the area with the average color. ![]() PDF Create uses two methods for resampling: Resampling – Resampling reduces the number of colors used in an image. No Image (level 0) – removes the image completely.Īdditionally, there is a slider bar in the compression dialog which can be used to adjust the settings manually for better control.Image Place Holder (level 5) – removes 95% of the information from the image, yet enough is left to show a sense of the image.Low Quality (level 25) – removes 75% of the information from the image.Medium Quality (level 50) – removes 50% of the information from the image.High Quality (level 75) – removes 25% of the information from the image.Lossless (level 100) –compresses the image without losing any information, retaining its original quality.PDF Create has six preset quality settings: The more information removed, the smaller the file and the lower the quality of the file.
