Image Resizer

Using the ImageResizer from COM

While the URL API method is preferred, you can use ImageResizer with the COM API. This means VB6, VBScript, JScript, C++, and other COM-compatible languages can resize images, even if they're desktop apps or command-line scripts.

To make ImageResizer accessible to COM clients, you must follow the COM installation guide.

JScript example

//The first step is to create a configuration object (where you register plugins, configure stuff, etc.)
var c = new ActiveXObject("ImageResizer.Configuration.Config");

//This is how you install a plugin
var p = new ActiveXObject("ImageResizer.Plugins.PrettyGifs.PrettyGifs");
p.Install(c);

//This is how you generate an image
c.BuildImage("..\\Images\\quality-original.jpg","grass.gif", "rotate=3&width=600&format=gif&colors=128");

// You can even get diagnostics output if something's not working
// c.WriteDiagnosticsTo("advancedScript-1.txt");

//You can create different configurations
var c2 = new ActiveXObject("ImageResizer.Configuration.Config");

//And use them separately
c2.BuildImage("..\\Images\\quality-original.jpg","grass-ugly.gif", "rotate=3&width=600&format=gif");

//c2.WriteDiagnosticsTo("advancedScript-2.txt");

VBScript example

Set c = CreateObject("ImageResizer.Configuration.Config")

c.BuildImage "..\\Images\\tractor.jpg", "tractor-rotated.jpg", "rotate=45"

VBScript COM API example

Set c = CreateObject("ImageResizer.Configuration.Config")
c.BuildImage "tractor.jpg", "tractor-rotated.jpg", "rotate=45"

JScript COM API example

var c = new ActiveXObject("ImageResizer.Configuration.Config");
c.BuildImage("tractor.jpg","tractor-rotated.jpg", "rotate=45");

Using plugins

Set c = CreateObject("ImageResizer.Configuration.Config")
' This line installs the plugin, so it can enhance GIF output quality
CreateObject("ImageResizer.Plugins.PrettyGifs.PrettyGifs").Install(c) 
c.BuildImage "tractor.jpg", "tractor-rotated.gif", "rotate=45&format=gif"
