Picture Control, Introduction

The 4D Write commands of this theme allow you to manage pictures in 4D Write areas. Using these commands, you can insert, position and delete any picture in your 4D Write areas.

Note about picture references

When a picture reference is stored, it contains two pieces of information: the reference itself and the information concerning the picture.
When the document is loaded and the reference is calculated, if the result is a picture, the information about the picture are used. If the reference returns nothing (for example, if the expression referenced a picture but no record is loaded), the picture information is lost.
It is therefore important, when you use picture references, to make sure that the picture can be accessed before loading the document.
