These Thumbnails are built automatically whenever Page Images are assigned to pages.(see Add Page Images)
If no Page Images are used or had been added already in former versions, Thumbnails can be added using this “Build Thumbnails” window.
If no Page Images are available, thumbnails can be created offline, e.g. in making a screenshot of a page of a “life” book. Or designed using any dimage editing program.
If Page Images already are available, those Page Images can be selected to be used for thumbnails.
To select the Page Images either use the button and select the Page Images in the File Explorer/FInder-WIndow that opens as reaction. Or as better approach select all page images and then drag&drop the selction on the green field, dedicated to this.Especially if more than ~150 page images should be selected, using drag&drop is the only working option.
After the selection is made, a Window opens where all fields are listed in a table.
This serves as a tool to assign thumbnails to pages. mz3Tool attempts to make this assignment automatically, but a thorough check is recommended. There several options that help in making the correct assignment. Most are explained in the chapter Assign Page Images to pages. The controls available are very similar.
If everything is OK, the selected Page images can be converted into Thumbnails with a click on the “Add” Button.
If the assignment to pages is incorrect, only the correctly assigned thumbnails can be selected.
A selection is done the usual way: select single rows with a click of the left mouse button together with the “CTRL-Key”.
A block of rows can be selected in clicking first row of such a blick and then clicking the last row while the SHIFT Key is pressed.
Worst case making use of the “Advanced Options”: or renaming the Page Images should help.
Here special filter and sort options support in defining the correct assignment of page numbers to thumbnails.
If Thumbnails should be used at all can be set in Settings – Configure Javasript Settings:
Thumbnails for the mz3Viewer Version
The mz3Viewer version build thumbs automatically while the pages are loaded. The thumbnail bar consists of a row of “bubbles”, representing one page each. The preview of the page corresponding with the hovered bubble is shown over the actual open pages.
Alternatively, Thumbnails for mz3Viewer books also can be prepared offline. They must have the correct size (25% of the original page size), being named correctly. and saved in a folder named “thumbs/”.
This is not supported by mz3Tool.
For that, the path to the thumbnails must be set as “book Parameter”.
“thumbs_”(mz3 project name)”_lc”
With “lc” being the language code. The mz3Viewer version only supports thumbnails of one language. So it is up to you to decide what thumbnails to use in selecting the appropriate language code.
