RealCADD 5.40
Posted: Thu Jun 13, 2024 1:38 pm
Bonjour,
Here's an explanation of the main new features in this version:
The new version of RealCADD, version 5.40, allows you to work with pdf files in 2 new ways.
Previously you could only import pdf files into your drawings as images.
This option still exists, as does the ability to import jpg, pgn or other images.
With RealCADD 5.40, 2 new possibilities are offered:
- An annotation mode for pdf files,
- Vector data extraction from pdf files.
To do this, a new 'PDF' item has been added to the 'File' menu, with 3 commands:
- Annotate a pdf...
- Extract from a pdf...
- Export as PDF...
The 'Annotate a pdf...' command lets you select a pdf file and open it in a special annotation mode.
In this mode, the pages of the pdf file are displayed as background images without being selectable.
And you can draw on these pages with all the tools and capabilities of RealCADD.
You can save your file in RealCADD format so that you can reopen it later and continue your annotations.
When you have finished making annotations, use the "Export as pdf..." command to create a new pdf file using the original pdf file plus your annotations.
The "Export as pdf..." command only works for annotated pdf files.
As before, to create a pdf file from another drawing, you need to use the print function.
The "Extract from a pdf..." command, as its name suggests, extracts as many vector objects as possible (lines, polygons, text) from the pdf file.
Of course, there's no point in trying this command with a pdf file generated by a scan...
The pdf files must be vector pdf files, i.e. generated directly from a computer.
The aim of this mode is not to have a perfectly exact representation of the pdf but to recover as many vector objects as possible.
It is therefore possible to recover objects that are outside the visible areas of the pdf or that extend beyond these areas.
Bitmap images are not read.
The quality of text recovery depends on its encoding and there may be some loss of text.
Some software transforms text into polygons.
Vector objects are recovered as they were defined when the pdf file was created.
For example, dotted lines can be recognised as a succession of small lines and not as a single line.
Another example is that backgrounds are defined by some software as a multitude of triangles rather than polygons.
So the number of objects recovered can be high even for a fairly simple file.
For pdf files with several pages, the vector objects retrieved from the second page onwards are offset by the height of the previous pages plus a margin.
Please try out different pdf files and let me know if there are any problems by sending me the problem files.
Cordialement.
