I'm trying to make a negative of an image with transparency. instead of what it used to do in im 6, it's now negating the transparency for example: trans.png https://i.imgur.com/59ChY45.png convert trans.png -negate negative.png https://i.imgur.com/7pJDWxF.png Is there a way to preserve the original...

thanks, adding -channel RGB did it!

Another transparent issue with IM 7 migration. Here what I'm doing convert trans-flower.gif -colorspace gray clut.gif -clut out.gif trans-flower.gif https://i.imgur.com/iCUKp64.gif clut.gif https://i.imgur.com/rxnB0Yx.gif Desired output (im 6) https://i.imgur.com/XzrEi02.gif Output in IM 7 no transp...

for example

convert flower.jpg -background transparent -rotate 45 out.png

will have a transparent background

you'd think setting a color to transparent would enable alpha.. or some consistency.

Anyway thanks for tip!

Ok, that works, but it's weird that in other places I use -background transparent it works without -set alpha!?

Was using this in IM 6

How do i get a transparent background?

flower.jpg


convert flower.jpg -background transparent -shear 12x0 png:output.png

im 6.7.2


img 7.0.8

Thanks so much!

Not sure if this is a bug or if changes in implode or how region works in IM 7 Any idea on what's going on or how to fix? flower.jpg https://i.imgur.com/Pn47J4f.jpg convert -region '150x150+50+50' -implode 1 flower.jpg out.jpg IM 6 out.jpg (desired) https://i.imgur.com/WSFBwOU.jpg magick flower.jpg ...

Hi, Working through the changes in IM 6.7.2 to IM 7.0.8 .. Any way to make implode region more uniform like in IM 6 (ie, with out the box ) flower.jpg https://i.imgur.com/Pn47J4f.jpg convert -region '150x150+50+50' -implode 1 flower.jpg out.jpg IM 6 out.jpg (desired) https://i.imgur.com/WSFBwOU.jpg ...

I'm trying to find the best way to deal with bad colors being input.. For example: # convert -fill darkgold label:Test test.gif convert: unable to open image 'darkgold': No such file or directory @ error/blob.c/OpenBlob/3497. convert: no decode delegate for this image format `' @ error/constitute.c/...

Ok, thanks. I wouldn't have though that!

That doesn't work, I still get the same thing.

added the inputs above. ... with your changes still see the same problem. reversing order doesn't work though.

What happened to -radial-blur ? convert test.jpg -radial-blur 300 out.jpg convert: unrecognized option `-radial-blur' @ error/convert.c/ConvertImageCommand/2637. convert --version Version: ImageMagick 7.0.8-59 Q16 x86_64 2019-08-04 https://imagemagick.org Copyright: © 1999-2019 ImageMagick Studio LL...
