Using External Javascript Libraries

One of the things that I really wanted to bring to QBJS was the ability to include functionality from the wealth of Javascript libraries available today in an accessible way.

As an example, I put together a little proof of concept that utilizes the powerful CaymanJS image processing library. It allows you to do some pretty advanced image processing that you would typically find in an imaging editing tool like photoshop programmatically.

Import ImgProc From "https://raw.githubusercontent.com/boxgaming/qbjs/main/samples/include/caman.bas"

Screen _NewImage(844, 563)

Dim img As Long
img = _LoadImage("landscape.jpeg")
_PutImage , img

_Delay 1

Dim options As Object
'options.brightness = 10
options.contrast = 10
'options.saturation = 100
'options.exposure = -30
options.sepia = 60
'options.blur = 10
'options.noise = 10
'options.clip = 30
'options.sharpen = 80
'options.hue = 30

ImgProc.Render options
