When your active table (or SQL query result) includes BLOB fields (fields with large text data like Memo and CLOB, RTF data, OLE data, graphics etc), you can use Blob Editor to work with such data. To activate the blob editor double-click the corresponding column or choose Tools | Blob Editor.

The Blob Editor consists of several pages for working with different kinds of blob data.

Blob Editor

Text and RTF data

To work with BLOB fields, which consist of text data, use pages As Text (for plain text), As XML, As HTML or As RTF (for formatted text).

You can edit the contents of such fields if the active data set is editable. It is possible to find and replace the text there. The contents of such fields can be printed, loaded from a file or saved to a file.

Embedded Reports

In Database Tour Pro, it is possible to load reports from files to BLOB fields. Reports stored in BLOBs, can be previewed or printed directly from the BLOB Editor. To work with report in the BLOB Editor, use As Report page.

Graphic data

To work with BLOB fields, which consist of graphic data, use page As Picture. There are several formats supported (BMP, ICO, EMF, WMF, JPEG, PNG, GIF).

You can view and edit the contents of the graphic fields of the active data set.

If Stretch option is checked then picture size will be automatically resized to fit its window (you can resize this window), otherwise the picture is shown in its real size.

There is an ability to load pictures from BMP, ICO, WMF, EMF, PNG, GIF, or JPEG files to the database.

You can save the graphic contents of the BLOB fields to a file.

You can copy the graphic images from one field or record to another one (or from this application to another one and vice versa) by using clipboard.

You can print the contents of the graphic fields. There are three modes of graphic printing:

Other data

For other BLOB data, you can use As Hex page. You cannot edit such data directly, but it is possible to load the data from file or save it to file.

Advanced export capabilities

BLOB fields can be exported to another database, HTML or XLSX file etc. Moreover, each BLOB in a data set can be exported to a separate file in a batch mode (i.e. in one export step).
