At the bottom of the application, you will see a few options in the status bar. These will help you see and manage your active document.
Selection display mode – When you create a selection, you will see a shape that shows what you have selected. By default, this selection is shown as an outline, known as the marching ants. The selection display mode is a toggle button that will switch the display from marching ants to a color-based mask display. When the mode is changed from ants to mask, the selection mask will turn into a color. The colors for the mask option can be changed in Krita’s configuration. The section on selections (Chapter 4) will go over this in more detail.
Current brush name – This area will originally be empty when you start Krita. As soon as you select a brush from the brush presets, this area will display the brush name.
Document information – This displays the document’s color model and color profile information.
Document dimensions – This displays the document’s pixel width and height. This will always be shown as pixels. After the dimensions, you will see a number in parentheses with how much memory Krita is consuming. This area is clickable to reveal more diagnostics. The Appendix has more information on memory management, if you are interested.
Zoom information – This is a visual indicator to set the zoom level for the document. If you click the drop-down arrow, you will get options to change it to one of the predefined levels. This drop-down box can also manually accept number inputs. You also have a slider to the right where you can drag your pen to change the zoom level.
Pixel aspect ratio (PAR) – This toggle button changes how the pixels are displayed on the screen. By default, pixels are square, but this is not always the case, depending on your document. This was more common when standard definition televisions were used. With modern technology, nonsquare pixels are increasingly rare. More than likely, you won’t have to worry about ever using this.
