            PDFlib PHP macros and inline optlists
            Asked 2021-Dec-13 at 10:00

            I want to use macros and inline optlists within my PDFlib Script and it seems to work, but as soon as there is a "<" symbol in the text source, I get an error from PDFlib which says there is an undefined macro.

            Let's say we have the following text: $text = 'Lorem ipsum dolor sit amet < 0,11m²';
            If I do this everything works fine and the text will be displayed as this: "Lorem Ipsum dolor sit amet < 0,11m²"

            But as soon as I change < to the according symbol "<", I get the error Unknown option '0,11' in ... because PDFlib thinks a new macro is defined there.

            Is there any way to avoid this? Because obviously I don't want "<" in my text.

            ...

            ANSWER

            Answered 2021-Dec-13 at 10:00

            that is actually quite simple:

            the < character is by default the start character for an inline option in create_textflow. If you now want to output these characters as text, this naturally leads to a conflict, which you could solve as follows:

            • You can specify the < character as a character reference. For this the option charref=true must be set and you specify in the text <.
            • You use another character as start or end textflow character and define begoptlistchar and endoptlistchar
            • You do not use inline options, then you can use one or more add_textflow() calls to assemble the textflow handle.

            Please refer to the PDFlib Tutorial, chapter 9.2.2 "9.2.3 Inline Option Lists and Macros":

            The characters for bracketing option lists can be redefined with the begoptlistchar and endoptlistchar options. Supplying the keyword none for the begoptlistchar option completely disables the search for option lists. This is useful if the text doesn’t contain any inline option lists, and you want to make sure that »<« and »>« will be processed as regular characters.

            PDFlib PHP image boxsize with set height and dynamic width
            Asked 2021-Nov-18 at 11:15

            In PDFlib we can define the boxsize for an image using boxsize={65 65} (for example). Since we need two values, is there any way to set the height value and leave the width value to be dynamically? In my use case I want to add all images with a set height of 65, but the images can be different in their width so the boxsize should dynamically update according to the image.

            I also tried using scale in the option list, but that makes no sense, since the height than also changes according to the image.

            Currently I load all images I want to place using a for loop, which looks like this:

            The second parameter of getTextWidth() is not a string. It is really the font itself. Also make sure to get the correct font weight.

            PDFlib PHP return dynamic height of two elements side by side
            Asked 2021-Oct-19 at 08:47

            So, I have two elements side by side. Each of those elements contains a list and can be dynamic in their own height. But I have two problems with this.

            1.) How can I give the height of the highest element to the next element under those two? I know I can return the height value, but as of now this does not work as I want it to. If I return the height value of the left element, the right element, will not have the right start point in height and if I just return the height value of one, the next element will only get it's start point from that element. Means if I, for example, return the height value of the right element, the next element will get it's startpoint from that. But if the left element is longer than the right one, it doesn't display correctly. How can I achieve what I'm trying to do here?

            2.) The other problem is that the output as of now isn't correct. The items of the list come from an array. To display them I created a foreach loop which creates it's own textflow for every list item. The height of the next item will then be adjusted inside of that loop. The first two items display correctly as of now, but the third one and every item that comes after that doesn't get their right height value and will be displayed under the second one. Does anyone know what I'm doing wrong here?

            I have created two functions, one for the left element and one for the right. My Code as of now looks like this... Function for left element:

            PDFlib PHP place images next to each other
            Asked 2021-Sep-16 at 07:50

            I have multiple Images coming from an array (could be 3, could be 10) and I want to place them next to each other and if they don't fit anymore, place them in a new line.

            I have written a foreach statement and I got it to work, so that they place into a new line if they don't fit in the current one and they also place next to each other.

            But my problem is the spacing between the images, because as of now it's different for each image. Some have really wide space between them while others are overlapping.

            PDFlib table border only on bottom of row

            Is it possible in PDFlib to define borders for just specific rows of a table? I know we have the stroke option, something like stroke={{line=horother}}, which creates a border for the whole table (like in the example for all horizontal lines), but that's not exactly what I want to achieve. I want to define bottom borders for just some of the rows (to be specific, I don't want the header row and the last one to have any borders).

            PDFlib create svg graphic from other image
            Asked 2021-Aug-26 at 13:31

            Is it possible in PDFlib to create an svg graphic from another image-file (like png) and than put it out in the pdf? Like first load the png image with $p->load_graphics and than create a svg file within pdflib? I googled this but found nothing that fits my requirement.

            For explanation: I have a png graphic and want to create a svg file within my pdflib program, so I can give this image a shadow. Or is it possible to put a shadow on the image through another way?

            ...

            ANSWER

            Answered 2021-Aug-26 at 13:31

            You can only create PDF output with PDFlib. If you want to manipulate your SVG in advance you must do so before using load_graphics(). (this is not a functionality of PDFlib)

            Please note, however, that PDFlib does not support all possible SVG filters. Especially feBlend and feGaussianBlur, which are commonly used for blur shadows, are not supported. (Please refer to chapter 8.2.8 "Unsupported SVG Features" in your or the current PDFlib tutorial for details.)

            Therefore, the more sensible variant is probably to apply an appropriate shadow to the PNG image in advance by image manipulation (eg. by using ImageMagick) and load the final PNG to PDFlib.
