Database operation manual
7.12 Image management
Images are not inserted physically in the database. For each image of an
accident there is a record in one of the two tables AccidentImage5_1 or
AccidentImage5_2, with a field that contains an external link to the current
position in the file system of the relative image.
7.12.1 Input Application
When in browsing or input mode of IA, clicking on the button “Go to images”, it
is possible to manage images of the current accident: it is possible to add or
delete images or add and modify comments to image. When adding a new
image, it is possible to browse the file system of your local computer and
clicking on the image thumb or on the file name, automatically the image is
resized to obtain a high resolution and low resolution image and converted in
jpeg format if necessary.
7.12.2 Output Application
Clicking on the button “Go to images”, the OA will display in a new form all the
images at low resolution (thumbs) of the selected road accident case present in
the local cache memory on the file system.
By clicking on a particular thumb, the OA will check if in the local cache it is
available the correspondent high resolution image; if not, it will be downloaded
from Central Server and shown with the associated Comments.
