Hello,
I am using IrfanView 4.42 64bit version.
I have some images of different formats. Formats are one of JPG, PNG, or BMP. I need to convert them all into BMP format, 72*72 pixels, 8BPP, compression None.
When I use batch operations to convert my image collection to above desired format. Final images are all good except Compression is "None, Grayscale" in the final converted images.
I will be using computer vision training on final images and need to have compression as None.
My batch operations settings are as follows:
- Output format: BMP
- Advanced: RESIZE selected. Width and Height both are set to 72.
- Advanced: Use resample function (better quality) checked as default. Left as checked.
- Advanced: CHANGE COLOR DEPTH selected. 256 colors (8BPP) selected. Use floyd-steinberg dithering checked as default. Left as selected.
- Advanced: Convert to Grayscale selected.
- Advanced: Apply changes to all pages (TIF/PDF saving) checked as default. Left as selected.
My original image properties before processing is:
My converted image properties after processing is:
My desired final image should have properties like this:
Any help is appreciated.
Thanks & regards,
Ertan
