3.2. Personalization with raster graphics (F3 RAS panel)The F3 RAS panel is a specialized tool designed for applying raster graphics to a personalized PDF template. The program offers extensive support for file formats, handling not only the most popular standards, such as jpg, png, and tiff, but also gif, bmp, and jpg2000 formats. An important technical note regarding png files is that it is necessary to use a version without interlacing.
After loading the graphics into the system, the table in the panel automatically displays the key parameters of each file, including its name, dimensions in pixels, and the resulting dimensions in millimeters, which are calculated based on the resolution. The user can manage the size of images in several ways: by changing the resolution, manually editing the values in the table cells, or using the dedicated Scaling subpanel. The scaling system allows for great flexibility – if one of the values (width or height) remains set to 0 mm, the program will automatically and proportionally adjust the other dimension. Entering both values greater than zero forces a specific size, which, however, if the proportions are not maintained, can lead to deformation of the graphics.
Additional visual customization is provided by the Pre-print subpanel, which allows you to add a contour line of a specified thickness and color in CMYK, RGB, or spot color to the graphics. The user can decide whether the contour should be visible above or below the photo, allowing for the desired aesthetic effects. Precise placement of graphics on the sheet is done in the Node, coordinates, rotation angle subpanel, where, after setting the X and Y coordinates and the anchor point (node), you can use the position lock function (padlock icon) to protect the element from accidental movement during further work on the project.
Step 2: The next step will be to load the photos collected in the avatars folder into the table. When 400 files are loaded, the following information will be displayed in the following columns of the table: the page number on which the file will be placed, the file name, the width and height in millimeters (the H [mm] and V [mm] columns), the width and height in pixels (Pixels H, Pixels V columns). Width and height in millimeters are the result of dividing the size in pixels by the resolution. Changing the resolution changes the values in the H and V column.

In the menu available under the right mouse button, several commands are available to manage the selected row.
Changing the size of the graphics is possible by changing the resolution. In individual cases, you can manually change the size by editing the values in the cells after double-clicking with the mouse. You can also resize graphics by specifying scaling in the Scaling subpanel. If both values in this panel are equal to 0 mm, the raster graphics will be placed according to the sizes specified in the table.

If only one of the sizes is larger than 0, the other will be scaled proportionally.
If both values are greater than 0, the sizes of the graphics from the tables will be ignored and their sizes will be equal to the entered values. NOTE. Entering a value arbitrarily can deform the graphic.
Step 3: If both values are greater than 0, the sizes of the graphics from the tables will be ignored and their sizes will be equal to the entered values. NOTE. Entering a value arbitrarily can deform the graphic.
In the Scaling ustalamy wysokość zdjęć na 40 mm (szerokość = 0 mm). Takie ustawienia pozwolą na proporcjonalne skalowanie szerokości zdjęćsubpanel, set the height of the images to 40 mm (width = 0 mm). Such settings allow proportional scaling of the width of the images.

Step 4: Let's add a contour line to the photos. Go to the Pre-print subpanel. Select Add pre-print [1] option, set the thickness of the outline to 1 mm [2], and set the color of the outline: C 29, M 4, Y 0, K 0 [3] and uncheck Contour behind fill [4]. Unchecking this option will cause the outline to be drawn over the object (photo).
In this case, it is irrelevant to uncheck or check the Colored pre-print option, because the pre-print is not larger than the photo, that is, it is completely hidden under it.

Finally, we put the photo in the right place. In the Node, coordinates, angle of rotation subpanel [1] we set the coordinate values for the upper left corner of [2]: X=10, Y=26 [3]. Since this is the correct position of the object, it is a good idea to lock this position so that it is not accidentally changed. To do this, "close" the padlock located at the coordinates [4].
