I found the reason. The background images (scans?) placed in the background had some extreme distortions, which also caused the artefacts you saw at the baseline. For now, copy the following in Window > Macro Window and press Run:
for g in Font.glyphs:
for l in g.layers:
if l.backgroundImage:
l.backgroundImage.transform=(1,0,0,1,0,0)
print "Done."
This will reset all image transformations and then the file will not crash anymore.
We will see if we can prevent the crash in the future. Thank you for the file!
Oh !!! Thank you so much MekkaBlue for you very quick reply and your help. I have just tried this and it works ! I am very happy to see my file is going better now. I am lightened !!
I recently moved my images files, maybe it is the source of the bug…
You’re welcome. BTW just rediscovered an old script of mine that would have already done what I pasted above: mekkablue > Images > Reset Image Transformations.
Thanks again MekkaBlue for everything !
So, for people who would be interested by the problem : for my part it comes from an image background bug. I recently modified the x-height of my lowercases with the tool named “transform”. This one distorted all images I let in the background, at the same time. This extreme distortion seems to be the reason of the crashing… !
Here are images of what happened on my file :
first strange pink and grey lines appeared at the baseline of my glyphs
-Then, when I clicked on a specific letter (especially f, n, u …), it became like “frozen”, I couldn’t do anything and a few seconds later the software crashes
Then I have modified the pourcentage of the height and width of my letters. I click on “run”.
What I forgot is that I had hidden images in the background. (that I used at the very beginning of my typeface) and it seems that theses images were also impacted by the transformation I made.
Everything was good during 2-3 days and the file began to crash after.
Also, it is maybe a major information : here I reimport a new image for the test, but you have to know that before, the link of certain of my images were broken. I could see this icon :
I didn’t careful to remove them at all
