Image Data Types
When you define a field to store image data, there are a number of data types available. These data types are all variations of the Image data type.
|
Data Type |
Representation |
Uniface Action |
|---|---|---|
|
I, or Image |
Image (any source) |
Detects the image format and deals with it accordingly. |
|
I# |
Image (database) |
Image is assumed to come from an occurrence in the database (BLOB). |
|
I@ |
Image (disk file) |
Image is assumed to come from a disk file. |
|
I^ |
Image (glyph) |
Image is assumed to be a glyph and is retrieved from a library. |
|
I& |
Image (url) |
Image is assumed to be a file served by a Web server. Only for use in server pages. |
The advantage of the I^ and I@ data types is that you only need to specify the name of the image or glyph in the field, and Uniface loads the image file or glyph, as appropriate.
