Add a logo to the shipping label

With RocketShipIt you can add a logo or image to any shipping label even if the carrier's API doesn't directly support it.

Currently supported label types:

Although, RocketShipIt allows you to place your logo anywhere on the label. Typically logos are added to an extended 4x8 shipping label. A 4x8 label is used to provide two inches of unused space at the top of the label for your logo. This helps to prevent your logo from blocking out text or important barcodes.

To add your image include the label parameter and add a transformation.

Transformation

A transformation modifies the label returned by the shipping carrier. Currently only the add_image and add_text transformations are available.

field	type	values
type	string	`add_image`, `add_text`
data	string	base64 encoded jpg,gif,png data
starting_x	int	Horizontal position on label to place image
starting_y	int	Vertical position on label to place image
font_height	int	height of font for `add_text`
font_width	int	width of font for `add_text`

What kind of image can I use?

You can use:

Because thermal printers often only support pure black and white images, all color images will automatically be converted to black and white. If you want to limit distortions caused by the conversion use a pure black and white (not color or grayscale) image.
