Bug In Batch Conversion Options

[OliOS2]

Hi!
I have the following problem. (I am using PMView 3.24.)
I load a jpg-picture with greyscale. If i manually convert it to black/white (2bit) and save it as pcx, everything is ok. The original file has about 250 kb, the new picture has about 77 kb and when I load the new pcx file, 2bit as colour depth is shown!

But, when I do the same with the batch conversation, the new pcx file is 8bit and the colour count is 251 an NOT as expected 2.

I do the following steps in batch conversion (I hope the translation is correct, because I use the german version):
- conversion to b/w (with -75 %)
- change the size (nothing to do with my problem)
- save it as .pcx

Even if I insert the function "conversation to subscripted colour" as the 2nd step, with the setting to 2 colours, the new .pcx file remains 8bit.

Is there anything I am doing wrong or is this a bug?

Thank you very much in advance.

Bye says Oliver
