I try to add new font in my pyqt5 apps with this code:
I am sure that it has correct file path points to right files.
It can load it and add to font_db by succesfully printing font family.
font_db = QtGui.QFontDatabase()
for f in ['resources/fonts/GothamNarrowBold.otf', 'resources/fonts/GothamNarrowBook.otf']:
font_files = os.path.join(package_dir, f)
print(font_files)
font_id = font_db.addApplicationFont(font_files)
font_family = font_db.applicationFontFamilies(font_id)
print(font_family)
but I still get this error message.
qt.qpa.fonts: Populating font family aliases took 103 ms. Replace uses of missing font family "Gotham Narrow Bold" with one that exists to avoid this cost.
What I have missed? Somebody can help me to solve this problem?
thanks in advance.

I am able to convert HTML to PDF using syncfusion.
The issue I have is it doesn't obey the font sizes
var htmlText = "<html><head><style>body{font-size:50px;}</style></head><body>Hello</body></html>";
var convertedHtmlDocument = ConvertFromHtml(htmlText);
var ms = new MemoryStream();
var fpath = AppDomain.CurrentDomain.BaseDirectory + "myfile.pdf";
SaveToFile(convertedHtmlDocument, fpath);
ms.Dispose();
It doesn't matter if I make the font size in the CSS 50 or 5, the font comes out the same size.
I also tried (same issue):
var htmlText = "<html><head><style>.myclass {font-size:50px;}</style></head><body><div class="myapp">Hello</div></body></html>";
Exporting the above 2 to an .html document behaves as the syntax suggests.
If I change my CSS to use table then it works, but I want to have a single font size for the document, not just the table
var htmlText = "<html><head><style>table{font-size:50px;}</style></head><body>Hello</body></html>"; //this works
What am I doing wrong?
We have checked the reported issue with different font size but it is working properly on our end. We have attached the sample and output for your reference.
Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/WPF1621828031
Output: https://www.syncfusion.com/downloads/support/directtrac/general/ze/Output259867595
If still you have facing the issue, we request you share the modified code sample, input html text and product version ,screenshot of the issue to check this on our end. It will be helpful for us to analyse and assist you further on this.
I'm trying to extract text from a PDF in python, but I get the following warning message which limits the amount of text for each page that is extracted. Is there any solution anyone can think of to resolve this issue? Code also below:
WARNING:pdfminer.layout:Too many boxes (106) to group, skipping.
import slate3k as slate
with open("mypdf.pdf",'rb') as f:
extracted_text = slate.PDF(f)
print(extracted_text)
I have made a very basic animation in Blender (2.79) and I am trying to export it as a GLTF or GLB. I have succesfully installed the gltf exporter and am able to export both gltfs and glbs of unanimated models no problem.
As soon as I add animation and try to export however, I get the following error message
The animation is as about as simple as it could be, I'm just experimenting. Its just the default box that changes location and rotation across 3/4 keyframes.
I am new to Blender so perhaps I am missing a step but my process is as follows: Add box to the scene, add keyframes (LocRot), go to export as I would with a static object, this has the following (default) settings.
I have tried clicking Pushdown on the action sheet as I have seen suggested somewhere but it makes no difference.
Am I missing something? Please let me know if you need any more info in order to advise, I'm happy to share the file or whatever might help.
NB this will eventually be used in a-frame so any specific tips on export for that would be much appreciated.
So after seeing someone else's export settings (thanks to the a-frame slack channel) I have got this working. I needed to have force sample animations selected in the animation export settings. Then it exports no problem and works as expected. Answering my own question in case anyone else has this problem.
Thanks.
To export multiple animated objects with armatures, vertex groups should have unique names. Here's a little script to rename bones and vertex groups based on parent armature name:
import bpy
for obj in bpy.context.selected_objects:
if obj.type == "ARMATURE":
prefix = obj.name + "_"
for bone in obj.data.bones:
bone.name = prefix + bone.name
if obj.type == "MESH":
prefix = obj.parent.name + "_"
for vg in obj.vertex_groups:
if vg.name[0:len(prefix)] != prefix:
vg.name = prefix + vg.name
I'm trying to see how to embed fonts into my pdf/a.
I found a lot of answer but using iTextSharp.
In my cas I use iText7 and all I tried gave me the error:
"All the fonts must be embedded..."
I have a ttf file for my font but I didn't find a way to embed it into my pdf to use it...
Could someone help me?
Thanks in advance

As documented in the tutorial and as indicated by the error you mention ("All the fonts must be embedded"), you need to embed the fonts.
You are probably not defining a font, in which case the standard Type 1 font Helvetica will be used. These standard Type 1 fonts are never embedded, hence you need to pick another font.
The example from the tutorial uses the free font FreeSans:
public const String FONT = "resources/font/FreeSans.ttf";
The font object is defined like this:
PdfFont font = PdfFontFactory.CreateFont(FONT, PdfEncodings.WINANSI, true);
This font is used in a Paragraph like this:
Paragraph p = new Paragraph();
p.SetFont(font);
p.Add(new Text("Font is embedded"));
document.Add(p);
This is the C# version. If you need the Java version, take a look at the Java version of the tutorial:
public static final String FONT = "src/main/resources/font/FreeSans.ttf";
PdfFont font = PdfFontFactory.createFont(FONT, PdfEncodings.WINANSI, true);
Paragraph p = new Paragraph();
p.setFont(font);
p.add(new Text("Font is embedded"));
document.add(p);
If you already use this approach, and you still get the error, you probably have some content somewhere for which you didn't define a font that is embedded.
So I am working on generating PDFs using the report4PDF package(bob nemec) from the VisualWorks 8.1 software from Cincom. I am doing everything in 'smalltalk'.
However right now, the issue I am facing is that I can't get a checkbox
character to show up on the PDF.
So my code would go along like this:
pdfDocument := Report4PDF.R4PReport new.
exporter := SAGETEAPDFDataExporter onDocument: pdfDocument.
exporter currentText text string:' Available'.
"Followed by relevant code to save PDF"
But what shows up on my PDF is basically ' Available'. A space appears instead of the checkbox symbol. I even tried using dingbats codes(e.g: #9744 ). Works with the copyright, alpha, gamma symbols. Not with the checkbox symbol.
I tried updating my VisualWorks image from the public repository using the report4pdf, pdf development and fonts development packages. Ran into some
issues which I wont mention since it will derail us from the topic.
Thanks in Advance!
Okay... So I ended up finding a solution to this question. I will just
post the answer here just in case anyone else gets in a similar situation.
pdfDocument := Report4PDF.R4PReport new.
exporter := SAGETEAPDFDataExporter onDocument: pdfDocument.
exporter currentText text:[:text|
text string zapfDingbats ;string:'q'.
text string helvetica; string:'Available' ].
So you can use dingbats font to get a similar character for checkbox. You use
mixed fonts to get something like this:' (Checkbox) Available'.
So that's like the string is: 'q Available'. But 'q' is of the dingbats font while the 'Available' substring is of Helvetica.
Hope that helped. And thank you again #Leandro for trying to help me :)
Cheers!
