Help+Manual comes with its own powerful graphics program called Impict for editing and enhancing screenshots and other graphics. This editor has a wide range of powerful features for making professional help graphics and screenshots.
By default, IPP images are non-transparent and their background is the solid color that you define for the image canvas in Impict. However, if you wish you can also change a setting in Help+Manual that converts the IPP image background to transparent. Then the canvas background color will be transparent and the image will be exported as a PNG image with an alpha transparent background.
Setting for transparent IPPs
Go to View > Program Options > Editor and activate the option Treat Impict images (*.ipp) as transparent and ignore the background.
The great advantage of Impict is that all effects and objects you add to your images are non-destructive. You can always go back and edit your screenshots later if you need to make changes – you don't need to rebuild the entire screenshot.
Texts in Impict images can be exported to XML files for translation. See the Impict help for details.
For all these features you must save working copies of your images in Impict's own IPP format – you can't save editable objects and texts in standard formats like BMP, GIF or JPG.
