I can’t imagine not using bitmaps inside of my CorelDRAW files. There are some projects without them, but most projects use a number of separate bitmaps. It is easy enough to convert bitmaps to a different color mode or change the resolution. But using the native features of CorelDRAW, you have to change each bitmap individually. That could take a lot of time if you have a bunch of bitmaps to modify.
When you need to modify a number of bitmaps in a document, you can use the Bitmap Manipulator v1.2 macro shown at right. Notice it allows you to change the selected bitmaps, all bitmaps on a page or every bitmap in a document. That includes bitmaps within groups or PowerClips! Look at the rest of the dialog box and you can see all the other changes you can automate.
For bitmaps that have an alpha channel (transparency), the alpha channel will be preserved. You can even use the Adaptive Unsharp feature to sharpen images after resampling. Even better, the macro has been updated to work with CorelDRAW X6 64-bit. With the time saved by using this macro, it could easily pay for itself with only a single use.
