Problem

RGB Alpha is not an available mode when saving images.

RGB Alpha is no longer available as an option when trying to save an image of the file (Utilities > Image > Save). In previous versions of MicroStation, user was able to set Format to an alpha-capable file type (such as PNG or TIFF), and choose RGB Alpha as a setting for Mode. Now, RGB Alpha is no longer an option under the mode setting, even with a compatible file type.

Solution

To enable mode RGB Alpha when saving images:

1. Set the variable _USTN_QVSAVERGBA to 1
2. In the Save Image dialog, set Format to one of the following alpha-compatible images:

• Portable Network Graphics (.png) 
• Tag Image File Format (.tif or .tiff) 
• Targa (.tga) 
• Adobe Photoshop (.psd)

RGB Alpha will now be an available mode.
