User-created filters can have color management, image effects, PDF retouch, domain selection and comments. The Color Management section allows assigning a profile, choosing a default profile, rendering intentconverting to a profile or intermediate transform.
The Intermediate Transform section allows adjustment of brightness, tint, hue, saturation, bilevel high pass filter or profile assignment, to either grayscaleRGB or CMYKor all data in the file. This can be applied to either text, graphics, images or shading.
Complex filters can be created by stacking multiple effects. Calculator can convert between RGBCMYK and other color value schemes, and features an interactive color-picker for identifying a color on the screen, duplicating a feature of another bundled utility, DigitalColor Meter.
ColorSync is Apple Inc. Apple developed the original 1. Apple, with the help of Adobe had ported ColorSync 2. Human color perception is a very complex and subtle process, and different devices have widely different color gamuts or ranges of color they can display.
To deal with these issues, ColorSync provides several different methods of doing color matching. For instance, perceptual matching tries to preserve as closely as possible the relative relationships between colors, even if all the colors must be systematically distorted in order to get them to fit within the gamut of the destination device.
Because the human eye is more sensitive to color differences rather than absolute colorsthis method tends to produce the best-looking results, subjectively speaking, for many common uses, but there are other methods that work better in some cases.
All image input and output devices scanners, printers, displays have to be characterized by providing an ICC profile that defines how their color information is to be interpreted relative to this reference color space.
This profile might be provided by the device manufacturer, but for better quality results, it might be generated by performing actual measurements on the device with a colorimeter. Thus, when an image is scanned on a scanner, the image file will include a copy of the scanner's profile to characterize the meaning of its color information.
Then, before the image is sent to an output device, a matching process converts the color information at the time of rendering from the source profile that attached to the image to the destination profile that attached to the output device so that the resulting colors print or display as closely as possible to the original image.
Console[ edit ] Console is a log viewer developed by Apple Inc. It allows users to search through all of the system's logged messages, and can alert the user when certain types of messages are logged.
The console allows you to read the system logs, help find certain ones, monitor them, and filter their contents. The Log List opens a sidebar which shows all of the different logs that the system maintains.
This list helps in viewing the many different logs maintained in various parts of the system by bringing them all together to one place.
By clicking on a particular log category, all of the logs will be shown. This includes system logs as well as individual application logs. This includes all activities from both the system as well as any applications running. Logs in this section of the Console are all formatted uniformly.
They all include a timestampthe name of the process or applicationand the actual message of the log.
When the message displayed includes a paperclip icon next to it, it means that it is a shortened version of a longer report, and clicking the icon will show the complete report. These custom queries will filter the messages and will also be shown in the All Messages section.I just start to write a simple script using shell in Unix OS, I tried to write a simple calculator the code first, the code let the user choose an .
