Re: How to know the image's transparent space?

Hi, when I used this command to trim the white space, if get output like 0x0+4500+5400, can I assume it is a fully transparent image when I use IM6? for the other method to take care of this is a bit slow, I want to combine to see if I can tell from this command convert SHIRT_ART_IMAGE1.png -format ...

Re: Image Magick 7 VS 6, for some command not working in 6, but 7 is much slower

for 6 we are using 6.9.4_1 ( 6.9.4_1.203308.0 )
for 7 we are using 7.x ( 7.x.200529.0 )

so is there any way to increase the speed of 7? if not we will stick with 6

Image Magick 7 VS 6, for some command not working in 6, but 7 is much slower

Hi, I am working in industry and need to use image magick to process images. I stated using image magick last month, with image magick 6.9, it works well, then for some use case, like detect transparent image and compare image, result of 6 doesn't match result of 7, and I believe result of 7 is corr...

Re: How to know the image's transparent space?

Re: How to know the image's transparent space?

thanks, it works

I have another question, so currently I am running two commands in my java application. one is scale image, the other is remove transparent space and get image offset, what I mentioned in this post, but it running is too slow, is there a way to increase the processing speed?

Re: How to know the image's transparent space?

thanks for you answer, in this case, I only care the image is fully transparent or not fully transparent, I think I would go with this command, if there is other shorter one, since I use java code, so shorter one might be clearer, but if not, it is fine convert transparent_image.png -channel a -sepa...

I don't want to know some transparency what ...
