Here we go with another set of tips and tricks.
As you know, 4D Knowledge Base is a library of information about the 4D technology where weekly tech tips and monthly technotes are actively published. If you missed the last tips on the KB, that’s fine; here is a compilation from the past few weeks.
This blog post covers 16 tips:
4D Write Pro documents can contain images from different sources and in various formats. These images may, in some cases, not be displayed for totally reasonable reasons — such as invalid URLs, formulas returning empty images, formats not supported by the platform, etc.
However, they are always represented by a small empty rectangle showing their theoretical location. If you want to change this behavior, 4D v19 R6 is shipped with a new view option enabling you to make empty images completely invisible.
Images are an essential part of documents. On an invoice for example, getting the right positioning for the company logo is important. That’s why the 4D Write Pro interface component offers a property dialog for images. You or your end users can easily define:
- the size of the image
- the display format
- the margins and padding
- the position on the page for anchored images
Starting with 4D v19 R2, inline as well as anchored images inside 4D Write Pro documents will benefit from new formatting types.
We’ve also made it much easier to format the images used as background of documents, sections, paragraphs, etc.
Let’s find out more about these enhancements.
4D Write Pro brings good news with 4D v18 R2: deleting inline or anchored pictures can now be done in a snap! Say hello to the new command, WP DELETE PICTURE.
Sometimes it’s preferable to have the lines of an object keep their original width, regardless of the applied transformation. For example, you draw a line on a map showing a user’s position and a destination. When the user zooms in on the map, you want to enlarge the map but have the line maintain its width.
Flash news: 4D Write Pro anchored images now support 4D Expressions!
Since 4D v16 R6, it’s been possible to add anchored images to 4D Write Pro documents. Once inserted, these images were static, either defined with a picture variable (or field), or by a picture path. Today, you have more flexibility: a valid 4D expression can also be associated to an anchored picture!
Unless you’re Stephen King and planning to write the next best seller, you may want to avoid long block of texts. And you can do this by using illustrations and images in your documents! Luckily, working with pictures in 4D Write Pro is evolving with every release, and these graphic-related features allow you to breathe life into your drab black and white text documents. In this blog post, we’ll explain the different types of pictures in 4D Write Pro, their use, and how to take advantage of them to create visually compelling documents!
Pictures speak louder than words, or so they say. In fact, according to researchers the brain processes images 60,000 times faster than words. 4D Write Pro is constantly evolving, version after version, to support more and more picture-related features. After in-line pictures and background pictures, 4D v16 R6 gives you the full control over picture insertion at a specific position in a document, in front of or behind text, as well as anchored to the page or specific parts of the document (i.e., header, footer, sections).
This blog post explores a 4D Write Pro-related functionality which will help you with the creation of complex documents, programmatically. Documents that can be either printed or sent by email.
An expression can now be a Picture! Handling pictures in your 4D Write Pro documents is becoming easier, offering vast possibilities. From now on, any expression returning a picture can be inserted. The most obvious cases are fields and variables, but it goes also for 4D functions and, last but not least, your own methods!
