Figur 15.81. Pointer dialog

This dialog offers you, in a same window, in real time, the position of the mouse pointer, and the channel values of the pointed pixel, in the chosen color model.

#### 5.8.1. Activating the dialog

The ”Pointer” dialog is a dockable dialog; see the section Avsnitt 2.3, ”Dialoger och dockning” for help on manipulating it.

You can access it:

- from the image menu: Windows → Dockable Dialogs → Pointer.

- from the Tab menu in any dockable dialog by clicking on and selecting Add Tab → Pointer.

#### 5.8.2. ”Pointer” dialog options

Bildpunkter

  Shows the position of the pointed pixel, in X (horizontal) and Y (vertical) coordinates, stated in pixels from the origin (the upper left corner of the canvas).

Enheter

  Shows the distance from the origin, in inches.

Pointer Bounding Box

  This information is active when a selection exists. X and Y are the coordinates of the upper left corner of the rectangular frame that bounds rectangular and ellipse selections. H and W are the height and width of this box.

  This information also exits for the other selections, but they are of less interest and the bounding box is not visible.

  This information concerning the selection remains unchanged when you use another tool, while pointer coordinates vary.

Kanalvärden

  The channel values for the selected color model are shown below. Both pulldown menus contain the same choices, which makes it easier for you to compare the color values of a particular pixel using different color models. ”Hex” is the HTML Notation of the pixel color, in hexadecimal. The choices on the pulldown menus are (Pixel is the default):

  Bildpunkt

    The RGB channel values. This choice displays the Red, Green, Blue and Alpha values of the pixel, as numbers between 0 and 255.

  RGB

    The RGB channel values. This choice displays the Red, Green, Blue and Alpha values of the pixel, as percentages. It also shows the hexadecimal value of the pixel's color.

  HSV

    The HSV components. This choice displays the Hue, in degrees, as well as the Saturation, Value and Alpha of the pixel, as percentages.

  CMYK

    The CMYK channel values. This choice displays the Cyan, Magenta, Yellow, Black and Alpha values of the pixel, as percentages.

Sample Merged

  If this option is checked (default), sampling is performed on all layers. If it is unchecked, sampling is performed on the active layer only.
