Hello,
I try to generate photos thumbnails jpg with white background. I use this command :
Code: Select all
convert -size 100x100 xc:none -draw 'roundRectangle 0,0 100,100 15,15' -fill white original.jpg -compose SrcIn -composite thumbnail.jpg
But I dont understand why it's not working (I obtain black corner).
It's great with png out but the image is too bigger ! 40 Ko for 100x100 simple png...
Thanks !

I do not know if this is a valid way to use ImageMagick and I could not get all the code on one line:
Code: Select all
composite -compose Dst_in ( convert -size 100x100 xc:none -fill black -draw "roundRectangle 0,0 100,100 15,15" ) house.jpg -matte thumbnail.png
convert -size 100x100 xc:white thumbnail.png -composite output.jpg
Your black corners are still comming from the transparency.

Thanks to your answer. I've use a similar way with 2 command line.
The first on my previous post and
Code: Select all
convert thumbnail.png -background white -flatten thumbnail_out.jpg
And after "rm thumbnail.png"
Bye !

while flatten will not work with mogrify for in-place image modification, (it is a multi-image layers operator after all. an alturnative is border.
mogrify -bordercolor white -border 0x0 thumbnail.png
