    I'm using CairoSVG in a project of mine
    Guillaume Ayoub
    @liZe
    Cool :)
    Michele Mostarda
    @michelemostarda
    Great project anyway
    Guillaume Ayoub
    @liZe
    Thank you

    When rendering an svg on my dev laptop (osx) I get a certain rendering, when using it on prod server based on linux ubuntu I get a really different one, despite I installed the same font set used in SVG
    Guillaume Ayoub
    @liZe
    Oh :/. Could you please share the SVG file and the renderings?
    Michele Mostarda
    @michelemostarda
    sure
    this is the svg
    Guillaume Ayoub
    @liZe
    Hm… It’s truncated. You can attach files with a simple drag and drop.
    Michele Mostarda
    @michelemostarda
    this is the rendering on osx
    d&d not working

    this is the SVG template

    This is the image rendered on osx
    Michele Mostarda
    @michelemostarda
    This is the same template, same code, generated on ubuntu

    The fonts are different, that’s probably the only problem you have. Your Ubuntu box can’t find the Avenir-BlackOblique font.
    How did you install the font on Ubuntu?
    Michele Mostarda
    @michelemostarda
    fc-list | grep BlackOblique
    /usr/share/fonts/custom/Avenir-BlackOblique.ttf: Avenir,Avenir Black Oblique:style=Black Oblique,Regular
    /usr/share/fonts/truetype/custom/Avenir-BlackOblique.ttf: Avenir,Avenir Black Oblique:style=Black Oblique,Regular
    /home/affilio/.fonts/Avenir-BlackOblique.ttf: Avenir,Avenir Black Oblique:style=Black Oblique,Regular
    custom installation, in several locations, to be sure
    Guillaume Ayoub
    @liZe
    Can you launch fc-match "Avenir-BlackOblique"?
    Michele Mostarda
    @michelemostarda
    fc-match "Avenir-BlackOblique"
    Avenir-Book.ttf: "Avenir" "Book"
    Guillaume Ayoub
    @liZe
    That’s not the black oblique version of Avenir, that’s why it doesn’t work.
    I think that "Avenir Black Oblique" will work, instead of "Avenir-BlackOblique"
    Michele Mostarda
    @michelemostarda
    fc-match "Avenir Black Oblique"
    Avenir-BlackOblique.ttf: "Avenir" "Black Oblique"
    Guillaume Ayoub
    @liZe
    You can use this in the SVG file, it will work on Ubuntu. It will probably work on macOS too.
    Michele Mostarda
    @michelemostarda
    so I just need to replace the font family with "Avenir Black Oblique"?
    will try in a moment
    Guillaume Ayoub
    @liZe
    OK!
    Michele Mostarda
    @michelemostarda
    IT WORKS, thank you very much
    Guillaume Ayoub

    Hey guys, I have a query. My application is in Java. And I want to convert our SVG files to pdf. Are there any APIs exposed through which the application can connect to CairoSVG and get the file converted in realtime?
    Guillaume Ayoub
    @liZe
    @goyaldin Hello!
    The easiest solution is probably to use the command line interface.
    https://cairosvg.org/documentation/#command-line
    You can even use standard input and output to avoid temporary files.
    goyaldin
    @goyaldin
    yeah @liZe, I saw that but that needs installation on the server machine which I can't do considering the way our application is deployed on Kubernetes. I was looking more of a sort of exposed API which can be used by applications written in a different language than python. Please let me know if there is a feasible option for such a case.
    Guillaume Ayoub
    @liZe
    @goyaldin Some people install CairoSVG in a Python web application (a simple version is ~20 lines) that gets the SVG in a request and returns the image. That’s a good solution if you don’t want to install CairoSVG in your app, but it requires you to install another app elsewhere.

    @goyaldin
    thanks, @liZe for the suggestions. I will check out what can be done here

    Hey! I have a question regarding SVG2PNG function in python. When it rasterizes the vector format SVG to a pixel formatPNG, it automatically adds anti-aliasing feature (adding grayscale). Do you know what algorithm(https://en.wikipedia.org/wiki/Spatial_anti-aliasing) it performs? is it based on the percentage of the region that covers the pixel? if not, could you explain how it's performed? Also, are there other anti-aliasing options? how do I change that? Thanks!
    Guillaume Ayoub
    @liZe
    Hello @dlwns87!
    CairoSVG handles the shape-rendering and text-rendering to set different antialiasing options
