Text stroke cut off

Post by Marcel71 »

Hi,

In an old IM version (6) this was working properly, however with 7 the stroke gets cut of at the top and left side of the image and I get a smutchy edge. Does anybody know how to do this correct in IM7 (without changing the label text by adding extra spaces or \n)?

Code: Select all

convert -background none -fill "#ffff00" -font Arial-Bold -pointsize 60 -interline-spacing 0 -stroke "#ffff00" -strokewidth 32 label:"Fred\nis\ngood" -stroke none label:"Fred\nis\ngood" -compose DstOut -composite +repage out.png
In IM 6.8.7-9

In IM 7.0.8-66

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ https://www.imagemagick.org/download/beta/ by sometime tomorrow.

Hi Magick,

Thanks for the fix. In the meantime I came up with the following command to let it work on the current version :)
(First make a empty canvas with the size of the text and then annotote with a displacement of half of the strokewidth)

Code: Select all

magick convert -background none -gravity center -density 72 -fill "#ffff00" -font Arial-Bold -pointsize 60 -interline-spacing 0 -stroke "#0000ff" -strokewidth 32 label:"Magick\nIs\nCool" -bordercolor transparent -alpha transparent -write mpr:canvas +delete -gravity west \( mpr:canvas -stroke none -annotate +16+0 "Magick\nIs\nCool" \) \( mpr:canvas -stroke "#0000ff" -annotate +16+0 "Magick\nIs\nCool" \) -compose Out -composite -virtual-pixel background +repage out.png
Thanks,
Marcel

Hi magick,

The fix is good when the text is aligned West, but when the text is aligned Center or East is does not work properly:

Code: Select all

convert -background none -fill "#ffff00" -gravity Center -font Arial-Bold -pointsize 60 -interline-spacing 0 -stroke "#ffff00" -strokewidth 32 label:"Fred\nis\ngood" -stroke none label:"Fred\nis\ngood" -compose DstOut -composite +repage out.png
Regards,
Marcel

Thanks for the analysis. We reverted the text offset patch but kept the DstOut composition patch. You will bet proper text edges now.
