How to Create Webpage Thumbnail with HmlCapture?

author — Fri, 18 Jan 2008 16:17:50 +0000

There are two successful ways to make html thumbnails — cropping and resizing. HtmlCapture ActiveX provides SetThumbSize() funtion for resizing and SetClipRect() for cropping. You can use either or a combination of both to make the smaller images.
If you want the thumbnail to give an overview of everything in the picture and don’t care much about the detail, use resizing. If you want the thumbnail to give a much better feel for what the full picture contains, use cropping.

Here are two thumbnails of http://www.microsoft.com/ — one of each type.

The following codes in JScript show how to get the above thumbnails with HtmlCapture component.
//create HtmlCapture var snap = new ActiveXObject("HtmlCapture.SnapShooter"); snap.SetRenderingEngine("firefox"); //set firefox as default rendering engine snap.SnapUrl("http://www.microsoft.com/"); //snap it snap.SetThumbSize(188, 242, true); //save a resized thumbnail image snap.SaveImage("microsoft.com_thumb.jpg");

snap.SetClipRect(0,0, 188, 242); snap.SaveImage("microsoft.com_cropping.jpg"); //save a cropped thumbnail image snap = null; //release the object

How to remove the blue lines on the captured image?

author — Fri, 30 Nov 2007 04:50:11 +0000

The blue lines are added because your HtmlCapture is trial version. Once you buy our product, an reg code will be sent to you. Then you call SetRegInfo() with your reg name and reg code before calling SnapUrl() to remove the lines.

Here’s the demo code for javascript:
var snap = new ActiveXObject("HtmlCapture.SnapShooter.1"); snap.SetRegInfo("Your REGNAME", "Your REGCODE"); snap.SnapUrl("http://maps.google.com"); snap.SaveImage("snapshot.png");

Is there any way to get rid of the white area of the captured image?

author — Wed, 28 Nov 2007 18:45:53 +0000

We can do this by calling the SetMinBrowserSize() function before calling SnapUrl(). The default MinBrowserSize is 800×600, so the minimum size of the output image is 800×600. The sample codes are listed as follows

SnapShooter snap; snap.SetMinBrowserSize(300, 200); //set minimum browser size to 300x200 snap.SnapUrl("xxx.com");
