The fonts I see supported through API is: Arial, Arial Black, Bahnschrift, Bahnschrift Condensed, Bahnschrift Light, Bahnschrift Light Condensed, Bahnschrift Light SemiCondensed, Bahnschrift SemiBold, Bahnschrift SemiBold Condensed, Bahnschrift SemiBold SemiConden, Bahnschrift SemiCondensed, Bahnschrift SemiLight, Bahnschrift SemiLight Condensed, Bahnschrift SemiLight SemiConde, Calibri, Calibri Light, Cambria, Cambria Math, Candara, Candara Light, Comic Sans MS, Consolas, Constantia, Corbel, Corbel Light, Courier New, Ebrima, Franklin Gothic Medium, Gabriola, Gadugi, Georgia, Impact, Ink Free, Javanese Text, Leelawadee UI, Leelawadee UI Semilight, Lucida Console, Lucida Sans Unicode, Malgun Gothic, Malgun Gothic Semilight, Marlett, Microsoft Himalaya, Microsoft JhengHei, Microsoft JhengHei Light, Microsoft JhengHei UI, Microsoft JhengHei UI Light, Microsoft New Tai Lue, Microsoft PhagsPa, Microsoft Sans Serif, Microsoft Tai Le, Microsoft YaHei, Microsoft YaHei Light, Microsoft YaHei UI, Microsoft YaHei UI Light, Microsoft Yi Baiti, MingLiU-ExtB, MingLiU_HKSCS-ExtB, Mongolian Baiti, MS Gothic, MS PGothic, MS UI Gothic, MV Boli, Myanmar Text, Nirmala UI, Nirmala UI Semilight, NSimSun, Palatino Linotype, PMingLiU-ExtB, Segoe MDL2 Assets, Segoe Print, Segoe Script, Segoe UI, Segoe UI Black, Segoe UI Emoji, Segoe UI Historic, Segoe UI Light, Segoe UI Semibold, Segoe UI Semilight, Segoe UI Symbol, SimSun, SimSun-ExtB, Sitka Banner, Sitka Display, Sitka Heading, Sitka Small, Sitka Subheading, Sitka Text, Sylfaen, Symbol, Tahoma, Times New Roman, Trebuchet MS, Verdana, Webdings, Wingdings, Yu Gothic, Yu Gothic Light, Yu Gothic Medium, Yu Gothic UI, Yu Gothic UI Light, Yu Gothic UI Semibold, Yu Gothic UI Semiligh

I noticed that Helvetica font isn’t supported. Is that the reason why? If so, how can I have support for it using the ruby gem?

If not, what could be the reason this is happening?

Helvetica is not available by default. Slides Cloud app uses standard Windows font collection, and unfortunately Helvetica is not there.

To extend the available font set, you can upload the fonts you need to a storage folder, and then speficy it as “fontsFolder” parameter for Convert method.
You upload fonts to the storage just like other files using UploadFile method.

You can see a simple example of using fontsFolder parameter here.

It implies that the custom fonts are uploaded to “fonts” folder on the storage.

I hope it helps. Please contact us in case of any further questions.
