any parameter to get 32-bit output, i use -quality 100, but the output is 24-bit and little bit blur(affects some small font, make it hard to read),
I want to avoid the processing of the image, and just direct stream copy, as what it is original as possible
my command,
montage.exe A[1-17].png B[1-17].png ---UNTIL--- Q[1-17].png -tile 17 -geometry -10-10 -quality 100 out.png

single process of one single 32-bit png although the output is 24-bit, but it doesn't get blur, weird and puzzled
montage.exe K17.png -tile 1 -geometry -10-10 -quality 100 K17_out-t1-q100-g-10-10.png

thanks

I am not sure if montage supports transparency. I have not checked that. But if it does, then try making your output PNG32:resultimage.png

Unless the image has some transparent pixels, 32-bit and 24-bit (8 bits per component) will look exactly the same. The value of -quality doesn't affect the choice of 24-bit or 32-bit output format, nor does it affect the appearance of PNG images. It only affects the amount of compression.

i chop the 10pix border first and not use the -geometry -10-10 in montage,
the blur now gone for my 17x24 each 1400x700pix montaged output
