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.

Are you sure this is not the problem? If interpolation is enabled during resizing, shades of gray will result.
Turn off the "Resample Pixels" ("Bildpunkte interpolieren") resize option, and the result should remain black&white.

Thanks,

Hi Peter!

Turn off the "Resample Pixels" ("Bildpunkte interpolieren") resize option, and the result should remain black&white.

That's it! Thank you very much for the hint!

Is it planned to implement batch conversation within subfolders?

Nobody has requested this feature...You could easily do this from an OS/2 command prompt by writing a REXX script...

BTW, I would suggest leaving interpolation enabled and instead doing the B/W conversion as the last step.

Thanks,
