Re: Transpose command line into Perl Script

I think I managed with:

Code: Select all

$my_image->Quantize(colors=> 256);
$my_image->Set('png:format' => 'png8');
Would this be the correct way? If you guys now something faster, do say.

Thank you

Transpose command line into Perl Script

Hello, I could not figure out how to transpose this into Perl syntax. The idea is that I have PNG32 images and I would need to convert them with the following settings to png8: my_image.png -colors 256 PNG8:my_image.png - work great in command line with desired output I tried with $my_image->Set(dep...

Re: Is is possible to get jpeg2000 from ImageToBlob?

Unfortunately I did not manage to install the support for it.

if I run indentify on my jp2 image, I get:

Code: Select all

test.jp2 PNG 300x300 3000x3000+600+900 8-bit sRGB 6.69KB 0.000u 0:00.000
I just ran

Code: Select all

convert test.png test.jp2
Is it possible the conversion is not ok?

Re: Is is possible to get jpeg2000 from ImageToBlob?

Hello,

I think you have solved my issue. I do not have the format listed.
I will try to install the support.

The thing is, that equery u shows that the support for jpeg 2000 is active. (through DCM* maybe )

Re: Is is possible to get jpeg2000 from ImageToBlob?

Hello,
I am still trying to use:

Code: Select all

 ImageToBlob(magick=>'jp2')
but with no luck.

I have a png file and I want to obtain the jpeg 2000 format from the script.
The error is an empty file."

Can someone please tell me how is the correct syntax that should be used?

Re: Is is possible to get jpeg2000 from ImageToBlob?

If this is not possible I would also need some insight in how to make my png8 files smaller...maybe? The only attribute that I am sending to ImageToBlob is magick -> png and quality-> 90
I am not sure if I could use some compression or something similar.

I appreciate any advice.

Re: JPEG XR support question

I too think this would be a great addition. Especially if it will be widely supported by web browsers.

Re: Convert PNG32 to Jpeg2000,reduce size and keep transpare

Hello, Yes, jp2000 supports transparency. I managed to fix it by running the same command as in the first post, but on version 6.7.8-8 2013-03-18 Q16 (on a virtual machine) For this version, when I run convert -version I have listed only these (no delegates) "6.7.8-8 2013-03-18 Q16" "Features: OpenM...

Re: Convert PNG32 to Jpeg2000,reduce size and keep transpare

Hello,

I am using imagemagick-6.8.5.4 on Unix; if I use your example I just have a black box.

Do you have the jasper delegate library installed?

Check your delegates via

convert -version

does it list jp2 or jp2000
