BackSpace in "display" on MNG file crashes program

People,

This seems to be an old problem? - I am using Fedora ImageMagick-6.7.0.10-4.fc16.x86_64 .

I created two and three page docs with eg:

convert t1.png t2.png t3.png t.mng

Using "display" to look at the file, shows the last page but pressing BS to look at previous pages crashes the program. I am happy to help debug, fix etc if someone can point me in the right direction.

I have been using IM for many years so it would be good to give something back . .

Regards,

Phil.

Your command will create a single-frame MNG because here is zero delay between the images. Use -delay 100 (or any non-zero value) to make separate frames. All the same, it shouldn't crash so there is a bug. Thanks.

glennrp,

Thanks for that! Is there some way to now tell "display" to:

- pause
- allow stepping through the frames with a key press
- automatically resize the image to screen height

?

Thanks again,

Phil.
