Localization support

Some charts might be rendered for customers over various location with different currency and localization requirements. iclocale is a query parameter available to specify in what localization the chart should be rendered.

In the example below, check the thousands and decimal number separator as well as the currency position. Same chart parameters. Only iclocale changes.

3 improvements to QRCodes: colors, SVG output, no watermark!

We know lot of you use Image-Charts API to generate large numbers of QRCode on the fly. We've got 3 news for you:

  • 💎 No watermark: everyone can now generates watermark free QRCodes!
  • 🎨 Customize Background and Foreground colors: black and white is nice but what about other colors? Two new parameters let you customize background color icqrb=<hex_color> and foreground color icqrf=<color>.
  • 🪁 SVG Output: until now QRCodes were rendered as PNG. We've added support for SVG output as well. Use chof=.svg to do so.

What is the next improvement you would you like to see?

🎚 Generate GraphViz chart as png

GraphViz Charts are the perfect representation to organizational chart, model state machines, and any relation-based chart.

Until now Image-Charts supported only svg output and many of our users asked for png support for broader compatibility. Starting today, every graphviz chart outputs png by default.

For those you wish to still use svg output, use the chof=.svg parameter. Learn more.
