Re: how to ensure blurred text has enough padding?

Yes, that should also be sufficient.

Re: convert produces unreadable pdf

IM 6.7.8.9 is ancient. You would be best to upgrade. Also upgrade Ghostscript, since ImageMagick uses that to read PDF files. For us to be able to help, you will need to provide an example PDF. You can post it to some free hosting service that will not change the format (such as dropbox.com) and put...

Re: composite fails on /dev/fd/nn

If you use IM 7, then things have changed. You cannot use old convert syntax. Try

Code: Select all

magick composite png:<(magick -size 200 label:abcdefg png:-) -watermark 15 some-image.jpg > /dev/null
If you want to use the old convert and composite syntax, then you will have to back down to IM 6.

Re: re: Install ImageMagick on window

Yes, that is my recommendation. I do not think you can make it any better unless you rescan the document at a higher resolution/density.

Re: re: Install ImageMagick on window

I know little more about pdfimages. But I see no point in putting the extracted raster image back into a PDF vector shell. You will likely get the same degradation as in the original PDF file.

Re: Center a text problem

Another way, similar to what GeeMack suggested is to create a much larger background image than you need, then specify the pint-size and use -annotate to draw the text. Then trim and extend to the size you want. convert -size 2000x2000 xc:red -fill white -font OpenSans -gravity center -pointsize 328...

Re: Center a text problem

If you have upgraded imagemagick and it does not work, then try upgrading freetype delegate as well. I am currently using freetype @2.8_0.

Re: Center a text problem

Using IM 6.9.9.20 Q16 Mac OSX in command line, your equivalent commands work fine for me.

Code: Select all

convert -size 960x960 -background red -fill white -font OpenSans -gravity center caption:"MR" -density 144 -resample 72 MR.png

Re: composite fails on /dev/fd/nn

You are on IM 7. Things have changed a bit since IM 6. Use magick in place of convert. Also put magick before composite, identify, montage, mogrify, etc. I would really suggest you get out of the habit of using the limited composite and start using magick ... -compose -composite in its place. It is ...
