Select from  Menu - File - New Mazaika library

New library dialogue.

There are two tables for files at the the panel

Separate image files table - You may drag and drop files here from Finder application or you may use Add Files button and add images via Open File dialogue.

If you are using Photos, iPhoto or Aperture software to manage your pictures you may access images from Media - Photos tab at the sidebar of Open File dialogue.

Open media dialogue.

Folders with Images table - You may use images from any folder on your computer. To select a folder you had to add it to the table with Add Folder button and mark a line with checkbox.

Photo Jumble indexed only unique images. I.e. if some of your images are used in several iPhoto albums and/or image folders simultaneously, these images will be indexed only once. Your images will not be duplicated.

To count selected images, press Refresh Image Counter button.

Picture X/Y rate - Select proportions of library tiles here.

Crop - (default Center) If proportions of tiles you choose would be different from proportions of original image used as a tile only part of this image would be indexed. You may select what part of image: top, bottom, right, left or center would be taken.

Your original image would not be changed. There is no actual cropping of your original files. Cropped areas are only sampled and indexed into a Mazaika picture database. There are no modifications of your original images!

Stretch - Use this to stretch image to the needed proportions. Sometimes it is easier to spot cropped tiles than stretched ones. If Stretch is checked all tiles will be stretched to the Picture X/Y rate regardless of their original aspect ratio.

Margin % - (default 0) If there is white or black outer rim on your pictures, or if your pictures contain a large amount of space around the edges, you can crop it by increasing Margin % to more than 0.

Make Library - Press Make Library button to create a new library. You will be prompted to set a file name for library. When process would be completed new library would be open and ready to use for mosaic making.

Stop - Press this button to stop scanning process anytime. Library file will not be created.

Close - Press this button to Close this screen without library creation.

Advanced settings (Active only in fully registered version)

Sampling - (default 6x6) - When picture tiles are selected, the program must choose only The Best Tile. It could analyze a region as a matrix of Sampling size. This setting depends on the image tile count. General rule: more tiles in library - more Sampling size. Usually it is enough to use 6x6 sampling size for an average size library about 1,000 - 5,000 tile.

When you make RGBA color mode library, (images with transparency mask) you need to set bigger sampling value. We recommend sampling value about 12 or 14 for RGBA color mode library.

Thumbs Width - (default 36) Thumbs i.e. miniature copies of image tiles are stored in the library. They are used for preview of mosaic in the main screen and for creation of output mosaic with not very high resolution. Higher values for Thumbs Width will give you a clearer preview, but may decrease creation speed and increase resource consumption.

Thumbnail size don't have any effect on exported mosaic quality. When you export mosaic into image file, Full version Photo Jumble opens and draws your original images to recreate mosaic. This way you always have optimal tile quality. We don't recommend to use thumbnail size larger than 100 pixels.
