<p>I have written code to read a windows bitmap and would now like to display it with ltk. How can I construct an appropriate object? Is there such functionality in ltk? If not how can I do it directly interfacing to tk?</p>

Tk does not natively support windows bitmap files. However, the "Img" extension does and is freely available on just about every platform. You do not need to read the data in, you can create the image straight from the file on disk. In plain tcl/tk your code might look something like this:
```
```
package require Img
set image [image create photo -file /path/to/image.bmp]
label .l -image $image
pack .l
```
```
