Merge / Insert Demos Captured at Different Screen Resolutions

We’ve heard from customers that the ability to merge demos is an important capability of DemoMate that allows them to append and combine demo assets that have been captured separately. In some cases, however, the demos in question were captured at different screen resolutions, and won’t combine.

What to do?

Here’s a quick solution.

Simply resize the screenshot images from one demo to match those of the other -- using an image resizing tool. Programs like SimpleSizer, available from FileBuzz, let you resize images in bulk so you can adjust all the screenshot images in one demo to match the size of those in another demo. For example, let’s say you have a demo with screens captured at 1280x1024 and another at 1024x768, and you want to merge the two. Use SimpleSizer to resize the 1280x1024 images down to 1024x768, and then merge the two demos. Please note that this process has limitations — resized screenshots will blur slightly and the relative size of objects on screen will be different for the two demos. However, for some purposes, the result may be sufficient and justified by the time and effort you’ll save by not having to recapture an entire demo.

SimpleSizer can be downloaded from Simply point the application at the demo assets folder for the demo you want to resize (make sure to have it search subfolders) and specify the new size for your screenshot images. Once you have resized the images, merge the two demos by inserting one into the other.
