19.5 Database Input, Image Segment
The only database supported in this version is Microsoft Access. If you need a different Database supported, customization will solve this problem.
The Database consists of a set of tables. The table contains the locations of the images segments. Six fields specify the image segments: path, ID, x, y, w, and h. Database retrieval is specified by a query. For example, “Select Path, ID, x, y, w, h from List3”. Do not add “;” at the end of the SQL statement!
The result of a query must produce a list of (Path, ID, x, y, w, h). No other formats are accepted!
Example. Database Segment Input:
-
Start the software;

-
Click the “Source” button, and select file, “.\input_access\db1.mdb”;
-
Enter the SQL statement, “Select Path, ID, x, y, w, h from List3”;
