The The picture below shows Kate PDF Converter running on macOS Sierra.

6. Running Kate on Linux.

In On GNU/Linux operating systems, Kate PDF Converter has been packaged as a standalone AppImage file. This means the user only needs to grant the file execution permission and run it by clicking on it.

It is not necessary to install packages using commands like “aptitude” or “apt-get”. In other words, running Kate on Linux is perhaps easier than running other applications that require pre-installed dependencies.

The execution permission can be granted to the Kate executable file by typing the command chmod +x file_name in a terminal, or by right-clicking the file and changing its permissions using the graphical tools available in main desktop environments such as GNOME or KDE.

The picture below shows Kate PDF Converter running on Ubuntu LTS 16 and Debian Jessie Linux distributions:

7. Importing pictures to Kate session

You can add images to the Kate application by clicking on the icon. “Add images”.

This icon can also be found in File//Add Images as shown in the fallow picture:

Once you click the Add Images icon, a standard file selection window will appear, asking you to choose the image files you want to import into the Kate session:

It is worth mentioning that Kate PDF Converter does not directly manipulate your operating system files. You don't need to worry about Kate making changes to your files, as it works with an independent metadata structure.

The user can add as many files as needed. Kate PDF Converter uses an efficient memory management design that does not load the files directly into system memory. Instead, Kate only keeps references to the files (absolute file paths). This allows the application to handle many files without overloading the system's virtual memory.

8. Adding pictures to Kate using the drag-and-drop interface.

Kate’s graphical user interface supports drag-and-drop capabilities. This allows the user to add images to a Kate session by dragging and dropping files, just like in other applications. It is important to note that Kate PDF Converter will ignore any files that are not in a supported image format.

The picture below shows an example of dragging and dropping images into Kate.

9. Image formats supported by Kate.

Kate PDF Converter provides support for multiple image formats. The table below shows the supported formats.

10. Removing pictures from a Kate session.

With the Remove Selected Images tool, it is possible to remove images from a Kate session. The user must select the images they want to remove from the list on the left, then click the link to remove them.

11. Modifying the order of images in a Kate session.

Kate allows you to move a specific image up or down in the list on the left by using the tools highlighted in the picture below.

12. Cropping images.

Sometimes the user may want to limit the area of a specific image before exporting it to PDF. This is possible in Kate by clicking and dragging the borders of the crop rectangle. The user can also move the entire crop rectangle by clicking and dragging inside it. Everything outside the crop rectangle will be ignored when exporting to PDF.

13. Rotating images.

Kate can rotate a specific image using the tool highlighted in the picture below. By default, each click on the icon rotates the image 90° (to the left or right). It is also possible to change the rotation step in the settings.

14. Settings

In File//Settings the user can customise how the application works. The picture below shows the customisable parameters.

It's important to comment on some parameters.

• Page size corresponds to the size of the final PDF.

• Aspect Rotation modifies the final rendering of the image in the PDF file. The picture below explains the meaning of each available option:

• Type of rendering (filter) defines whether image transformations (such as scaling) should be smooth or not.

15. Exporting images to PDF

This is perhaps the most important feature of Kate. Once a session has been edited, it is possible to export the sequence of images into a single PDF file. There's nothing complicated about it—the user simply needs to choose a name for the PDF file and click OK. The picture below shows an example of the process.

It is important to note that once Kate finishes exporting, the PDF file is not opened automatically. The user must navigate through the file system and open the PDF manually.

16. Saving and opening sessions

Kate supports tools for managing sessions. In other words, the user can create a new session, open an existing one, and save changes.

Kate saves sessions as binary files with the extension *.kate. It is important to note that Kate is smart enough to identify whether a file is a valid binary created by the application. The table below shows the purpose of each tool used to manage sessions.
