Xara provides a number of Transparency types that can be applied to images, shapes and text for a variety of effects.
Each application results in a image being generated for the final result.
You might just accept that for images but destroying text, making it not Accessibly and ultimately blocky in appearance is not acceptable.
Equally, every effect, even to copies of the same image, will result in a different and separate image.
You have seen this image profusion with graphical Bullets and Xara NavBars and Buttons.

Xara changed its Transparencies in version 11, http://www.xaragroup.magix.net/XDP11/page-1.htm
New Blend Modes (Transparency Types)
The Transparency Types have been updated to be compatible with W3C (World Wide Web Consortium) standards. Mix, Stained Glass, and Bleach have been renamed using their industry standard names: Normal, Multiply, and Screen. Luminosity and Color have been modified to match W3C standards. Enhance remains the same (Enhance uses the Photo Tools > Enhance controls to adjust the transparency). Three new transparency types have been added: Overlay (a combination of Screen and Multiply) and can used to boost the contrast of an image. Hard Light and Soft Light are similar to Overlay but in slightly different ways.
An old explanatory guide is here: https://alistapart.com/article/blend...s-demystified/.
In the registry (at your own risk), you can re-activate the old transparencies with setting Computer\HKEY_CURRENT_USER\SOFTWARE\Xara\XtremePro Sub x64\18\Options\Displays\ShowLegacyTransparencyType s to 1.

My alternative avoids text blockiness, the production of hordes of images, keeps text as text and maintains Accessibility.
Essentially, you place a Shim, a shape that matches what you want to cover, or apply directly to a Text Area.
The Shim has a ClassName, htmlclass="mbm-..." applied and that's it.
There are 15 ClassNames to choose from, as demonstrated.
Each Shim or text has its own Fill and Stroke colours applied as you choose and, depending on the transparency type, this affects the rendering of the shapes under the Shim.

Do check there is effectively only one image in play.
Try using the Xara approach to see the difference.
