Convert Virtualbox .ova Image to .ovf

Debugging image color profiles is hard. You can't trust your eyes in this matter, as the image rendering depends on multiple factors. At least the operation system, browser or image viewer software and monitor influence the resulting image colors ...

Small web application where you can upload an image (PNG, JPEG, GIF) and generate a base64-encoded version of it.

You can copy the result as

• HTML <img> tag with data URI,
• CSS rule with background-image and data URI,
• plain Base64-encode...

Automatically convert bitmap images like JPEGs, GIFs and PNGs to the crisp, clean, scalable vector art of EPS, SVG, and PDF with the world's best auto-tracing software.

Conversion

ImageMagick can convert SVGs to raster image formats.

Example for PNG:

convert input.svg output.png

If the SVG has a size of 24x24 (viewBox="0 0 24 24"), the resulting PNG will also have a size of 24x24.

Resizing...

You can scale background images in CSS to the container size using background-size (Demo).

Commonly, we use contain or cover because we want to preserve the ima...

Auto-cropping

ImageMagick can automatically crop surrounding transparent pixels from an image:

convert input.png -trim +repage output.png

2. Get a Linu...

When you want to copy/move from a shared folder (on Windows guests, for example) and it fails with absurd error messages (lots of text or an error about the target being read-only), you are probably running on Guest Additions that no longer match ...

When you have a hex color code, you can easily convert it into its RGB values using plain Ruby.

>> "#ff8000".match(/^#(..)(..)(..)$/).captures.map(&:hex)
=> [255, 128, 0]

You can use that to implement a simple "hex to CSS rgba value ...

Say you have an RGBA color that you need as a non-transparent color because of reasons.
