This is a full circle flow from start to finish of a dynamic change of a picture from the photo mosaic. A sequence encompasses the timers for Blend -> Show -> Fly -> Pause. The sequence length is the sum of these timer values.

Picture library

A set of hundreds to thousands of pictures that is used to build the photo mosaic. Each of the library files will be resized to match with the size of the tile on the photo mosaic. It is recommended to keep the size of each library picture as close to the minimum required. It's therefore a good practice to manage the balance between size and quality:

• the smaller the library picture, the faster the resizing is done
• a picture which is too small will look pixelated when seen at full size during 'blend' and 'show'
• in general we recommend to keep the size as small as the maxmium size of the viewer screen. For example, a viewer size of 1920 x 1080 pixels (16:9 ratio) requires that portrait booth pictures of size ratio 3:4 should not be smaller than 1080 x 810 pixels, but also not so much larger. In this example case a booth and library picture should appr. be 1200 x 900 pixels in size.
• when new pctures are found via the tethered approach each picture is first resized to 1200 pixels on the horizontal (vertical follows the aspect ratio). This is required to keep the calculation time small for large bitmaps.

Tile

This is a sub-picture of the photo mosaic. A photo mosaic can exist from hundreds or thousands of tiles. The pixel size of the tile is set by the value of 'Size' in the 'Mosaic settings' settings. Also referred to as a 'Cell' .

Source picture

This is the basis picture of which a photo mosaic picture is made. The source picture should have pixel dimensions of at least 8 times the amount of tiles on the horizontal and vertical sides. For instance, when a photo mosaic is made from 80x45 tiles, the source file should at least have a pixel size of 640 x 360 pixels to assure a good color match. It is recommended to keep a safety margin of pixel dimensions of 16x the amount of tiles, so a source pixture size of 1280 x 720 pixels. In case 5-10 MegaPixel sizes are taken, the quality is not affected but the analysis of the source picture might take a bit longer (seconds).

Initial mosaic

The mosaic that is made from the library of pictures. This initial mosaic is made at the start of a video sequence and at the start of the show. The color matching of each of the dynamic tiles is derived from the initial and original colors. This way all dynamic flying tiles (substitutes) keep their best match with the original, assuring a good quality of the photo mosaic impression in due course of the dynamic tile changes.
