(restricted for Lite version, see below)
The Zoomer allows creating Collages from other images easy, Edit it and Print
it or save as image files. To start this mode, click toolbar button
or press
'T' key to drop down Tools pop up menu, and select an item Edit Collage and
Print there with the mouse or keyboard. Then, an Editing pane is appear in
place of the View area.

In this mode you can create really big images, print it, or save again as image files (jpeg, png) or in special format allowing you to save your collages to continue work in future. You can close the editing mode (or immediately close the Zoomer as usual), but next time you open Zoomer and go to the Collage Edit mode you will see your collage as you left it (except you should re-enter passwords for paroled images on it if any). The collage is saved very quickly as Autosave.zcg file. In most cases images itselves are not stored in that file, so if these were moved or deleted on disk, it will not be shown correctly next session.
In this mode, you can easy drag a single image from the File list (for multi-page images all the pages are added to the Collage), or drag (several) images from the another applications as files (such as from MS Internet Explorer or from any other file manager supporting dragging files). Or you can press button Open and select (multiple) files.
In most of modes you can select images using mouse as usual (or select it from Objects list at the right side). To unselect all the images, use rubber select on the empty area of the Collage, or click in the Objects list below all the items. Operations available for selected images, depend on the current editing tool set selected. To change tool set, use Tools pane at the left side. Buttons Tools and Objects allows you to hide totally or partially tools and objects panes, expanding working area. Also, in most of modes (except Printing) it is possible to change single (selected) image size dragging its marked corners with the mouse. But in such case aspect ratio is not preserved. To resize images keeping its aspect ratio untouched use tool set Resize.
Any time you can change zoom factor (it is always is calculated relative to images, even in Printing mode, while previewing printing pages). To change Zoom factor, use either zoom slider, or combo at the top right corner of the upper options pane (it is also possible to type any value from 1 to 400 % there, even not integer but as floating point number, e.g. 12.5 in percents).
In Printing mode, the collage is shown as a print preview. You can easy select paper orientation, gamma correction, colorization (it is possible easy print colored collage as grayscale or black and white only, and in the last case printing is very fast but for good quality (laser) printers can give even better result then grayscale).

Take into attention, that with the Zoomer you can easy print really big collages (or big single images) on several paper sheets. You just enter number of sheets in a row and number of rows, and the collage is stretched to it as you print in on a very big solid paper sheet. You can also change overlap for this case, to simplify later cutting task (e.g. if the printed sheets should be later glued together again to create a big size poster or placard).

When you divide big image onto many sheets, it is possible to select and print not all the pages, but selected only, e.g. to adjust printing quality spending less paper or to repeat printing of broken paper sheets only.
For Lite version, this mode is restricted and you can use it only to print a single (currently viewing) image. Any other editing options are not available, so this option is renamed for Lite version to Print (an item in Tools popup menu). Since Tools pane and Objects pane are not necessary, these also are removed, an image is always shown in Print preview (Printing) mode and a button Exit is moved to the Options (top) pane.
