Re: put JPG on diff-size background without loss of informat

Thanks so much for the quick replies!! -extent was what I was looking for... it should meet our needs. When I test the trivial case of using -extent to output the exact same size as the original, my file size GROWS by 9%, instead of shrinking by 5%. At least that could be attributed to data duplicat...

put JPG on diff-size background without loss of information

Hi all, I want to take a huge JPG and create a new, larger JPG consisting of the original JPG surrounded by a solid-color border. The new JPG should have the same IPTC metadata as the original (especially same colorspace). There should be no loss of quality for the original image in the center. Can ...

Re: PerlMagick -- needing to write/read file after every cha

I eventually found PerlMagick code to do what I needed. To simulate writing & re-reading everything from disk, I use: $p_sRGB = Image::Magick->new; $p_sRGB->BlobToImage( $image->ImageToBlob() ); Calling ImageToBlob() then BlobToImage() will do an in-memory "flush" of the image data. In my particular...

Re: WinXP PerlMagick Install

Re: partial transparency lost in composite -watermark

Hi Fred, Thanks so much for response. I'd already tried convert/-compose but, for me, they generated identical outputs to composite -dissolve and composite -watermark. So I don't think convert/-compose will help. Just now I also tried setting the colorspace to RGB & sRGB, but that did not cause my P...

partial transparency lost in composite -watermark

Hi, The "composite -watermark" command is not respecting the partial transparency of my PNG watermark. I'm using ImageMagick 6.7.7-8 2012-06-20 Q16 (i.e., latest version) on Windows 2008.
