Problem with extent and background colour

[manu_l]

I have a problem to convert files from tif to jpg. The size of the source pictures are different (81x100, 363x400,...) and it should result square pictures like 100x100, 300x300, 600x600. The transparent background in the tif-files and the extented space should be white. I've tryed this command:

Code: Select all

convert -resize 600x600 -background white -extent 600x600 -gravity center /pictures/10_test/90_00.tif /pictures/10_test/90_00.jpg

The problem is that the extented space is black:

source: 363x400

result: 600x600


IM-Version: 6.2.8


Can anyone help me with that problem?

v6.2.8 is very old. I suggest you update to the current version.

Then put the operations in the natural order: read an image, process it, write it.

Code: Select all

convert in.tif -resize 600x600 -gravity center -background white -extent 600x600 out.jpg

In v6.2.8, putting "-background white" before "-extent 600x600" might help. I don't have such an old version and can't test it.

Thank you for help - I will update the software to v6.8.9 and test it again

After updating IM it works with the code above perfect!
