Great, and thank you for the quick reply.

Hi,
Does PerlMagick 6.3.4 have this feature? It is documented in the PerlMagick manual, but when I do:

$image->Layers ('method'=>'optimize');

I get the error,

Code: Select all

Usage: Layers(ref) at ./foo.pl line 20

Great! Thanks!

Hello, I have described this bug here:

Thanks!

I want to request that this forum have a user-option to change the font size.

Thank you for for the replies. The commands mentioned work perfectly for PNG-results. but i ned the TIFF, because only the TIFF-images has right colorspace information and so on (PNG only supports RGB). If i just change the extension to .tiff the background is black and there's no transparency. Thi...

Thank you!

Hi,

Please see the experiment shown at this url:

Whether you want to call this a bug or not is a subjective matter, but I believe the images shown in the second table represent a more useful behavior of annotate.

Thanks, Anthony.

This works:

Code: Select all

convert Winter2.tif -matte -fill none -draw "color 0,0 reset" Winter2.tif \( Winter2.png -channel matte -negate -separate \) -composite test.png

I think a bug has been uncovered here. In the course of figuring out the command to do what you describe, I found this: This produces a transparent image, as expected: convert Winter2.png -fill none -draw "color 0,0 reset" test.png But if we use Winter2.tif as the source image, the output ...

Ah, so there will be a variable-space implemented with the percent-sign syntax like that found in -format. I think that's an exellent idea, and I look forward to it.

Hello, My feature request is to be able to crop to the geometry that was the result of the last trim, with a single invocation of convert. Anthony shows how to crop to the geometry of a trim via a subshell, at: http://www.cit.gu.edu.au/~anthony/graphics/imagick6/crop/#trim_blur convert noisy.jpg -cr...

Very interesting. Nice to see that ImageMagick is not at fault here, and indeed, has a feature that those other programs lack.

I was able to reproduce this bug on http://jjfoerch.com/bitbucket/cookie.jpg

This works fine:

Code: Select all

convert cookie.jpg new.pnm

This produces a corrupt image:

Code: Select all

convert cookie.jpg -gaussian 1x1 new-blurred.pnm

With the latest IM you can spedd up things as follows. neighbors='(p{i-1,j-1} + p{i,j-1} + p{i+1,j-1} + p{i-1,j} \ + p{i+1,j} + p{i-1,j+1} + p{i,j+1} + p{i+1,j+1})' rules="nn=$neighbors; ((nn<5)|(nn>6)|(nn==6 & u==1)) ? 1.0 : 0.0" convert gliders.png -channel R -fx "$rules" ...
