IM6 is limit thread 1 by default?

limit thread help, so now I am doing 1. limit 2. disable HDR 3. add quality to improve the speed, thank you guys!

-limit thread 1 just disable your 16 processors and forces Imagemagick to use just 1. It has nothing to do with HDRI. To disable HDRI or OpenMP, you have to recompile ImageMagick. I doubt disabling OpenMP will make a difference since -limit thread 1 did not seem to help. just one concern is what do ...

looks like limit thread helps and speed improve a lot!

oh I haven't try limit 1 yet, now I just tried disable HDR I found in some posts says it will help, I saw another suggestion is try add -quality 21?

Hi, does that mean HDRI has been disabled? looks like it is still slow. do I need also disable OpenMP? if it is, do you know how to do it?

oh the offset is correct, the bug I mean is the output is different, as I mentioned earlier in this post, there is transparency in the original pic but in the output these transparency are missing, the transparaency I men is on the image, like black ranger in the pic with IM6 original: https://drive ...

the one you talk about limit thread is this below?
convert -limit thread 1 src.png -resize 4000x5000! -format %@ -write info: -trim +repage -bordercolor none -border 5 dest.png

I try this but got errors

think it over I believe the bug happened in this command, sorry make you guys confused since our java application are using two commands together convert b.png -format %@ -write info: -trim +repage -bordercolor none -border 5 c.png the use case is I need to trim the transparency out of the image and ...

looks like I make it combine by this:
convert src.png -resize 4000x5000! -format %@ -write info: -trim +repage -bordercolor none -border 5 dest.png

is there a way I can combine these two commands into one?
so this is first command:
convert a.png -resize 4500x5400! b.png
this second command:
convert b.png -format %@ -write info: -trim +repage -bordercolor none -border 5 c.png

I am listing it only for IM7, I only have IM7 in this host
