7. The Menus / 7.3 Functions in the View Menu
If a document is displayed enlarged in PhotoLine, this means the zoom factor is larger than 100%, the pixels of images are displayed larger and larger, but text and vector layers are still displayed smoothly. In Pixel Mode this is different: if zoomed in, text and vector layers are as jaggy as images. The advantage of this mode is, that the display shows you largely the same result as the function "Reduce To Background" (see chapter 7.5.25) or the export to an image file format like JPEG. Only the interpolation method for images set in the Layer Attributes (see chapter 4.11) will not be taken into account in the screen output, as this could take too long depending on the image.
If this option is active, the title bar of the document will show "Pi".
If a document contains working layers, that work across pixels (e.g. a Gaussian Blur), PhotoLine automatically activates the pixel mode. In this case the pixel mode cannot be deactivated.
