In this case you can fill the white pixels with a slightly off white color like RGB(254,254,254).Д«oth of these approaches are painful but they are very reliable.

This is not always so cut and dried however because the image 'content' may also contain white pixels. By default BMP images display white pixels as transparent, so as long as you can easily represent your transparent content as white it's easy to do. You can also get transparency support with only BMP images. To me this has always been a non-starter. As you might imagine creating MASK files is a pain and adds clutter to your image management - anytime the image changes the mask has to be changed too and keeping things in sync is terrible. The mask file basically holds black dots for each of the pixels that should display and white content for anything that should be transparent. The most reliable way to get transparency in FoxPro involves using BMP files and a matching BMP Mask file. Prior to version 8 only BMP images were directly supported in the product and there are a couple of mechanisms used for handling transparency with BMPs. GDI+ support for graphics was introduced with Visual FoxPro 8. GDI+ image support for non-BMP images is actually a relatively new feature in FoxPro. Old School Transparency Support: BMP Image The bad news is that there are tradeoffs and extra work required to make it work properly. The good news is that with a bit of trickery you can get FoxPro to render transparent images. As a matter of fact all container controls have a picture property and the same rules apply.Д«y default only the Image control supports transparency properly for all GDI+ image formats. ComboBoxes and Listboxes as well, although it's less of a problem there because the background of lists tend to be white. Similar situation arises with other controls that have picture properties like OptionButton, Checkboxes. The first button doesn't show transparency and looks terrible, while the second button properly shows transparency and appears like it should using one of the approaches mentioned below. Specifically, here's an example of what I've been struggling with, which is buttons with associated icons: However, displaying transparent images on other controls that have a Picture property, unfortunately doesn't work as smoothly. If you load up an image control with a GIF or PNG file, the transparency is preserved and the image displays correctly. Specifically the FoxPro Image control supports transparency of the various transparent image formats. Although FoxPro supports most common image formats including GIF and PNG that support transparency, the transparency isn't supported everywhere within the product.

Overlayed bitmaps in FoxPro have always been a royal pain, but in order to make a UI that looks clean, getting some sort of transparency to work with FoxPro controls is pretty important.
