Hi,

Couple of years ago I was using this line:

mogrify -format png -alpha off -bordercolor Black -border 1 -alpha on *.png

to add a 1 pixel Black border around all the images in a folder while maintaining their transparency. Now it's not working anymore, the transparency is filled with black ...

Ah, it seems to work like this
Thanks for the help!

Still getting Syntax Error after
I also tried putting everything in one line, but I get the same error...

I'm using Windows, in case it matters... and I launched that from a bat file.

I tried replacing 000 with 0, but still the same.

First -- you can not output to a 'wildcard' filename! That just does not make any sense


Yeah, I know... I wanted to show that there should be different files.


As for the series.. try this...
for i in {000..359}
do
convert test.png -alpha on -virtual-pixel transparent \
-distort ...

I want to apply this code, more or less:

convert test.png -matte -virtual-pixel transparent \ -distort ScaleRotateTranslate 1 *.png

to generate a series of images, each rotated 1 degree more than the previous one. So, I start with test.png which will be at 0 degrees, test1.png will be at 1 ...

Perfect, man! Thank you!

OK, here's a link: http://rapidshare.com/files/406731031/bigarrow3.zip.html

Wouldn't flatten remove the transparency, though?

And keep in mind that I need the graphics to be in exact the same position as they are in the psd. For example, if I had a layer with just on pixel on it at the position ...

Hi,

I'm trying to convert the layers from a psd file, each in a png on its own. The problem I have is that the layers don't fill the canvas, so each png file is created with a different size, depending on how much graphics is on them. I need them to keep the same size as the psd, their exact ...

Aha! Perfect! Thank you very much!

you can also use -geometry -1-1 to try to eliminate extra space

I've tried that, but that cuts the edges of the final image plus the images will not overlay as needed. I need the first left column of pixels of an image to overlay with the last right column of pixels of the previous image so the 1 ...

Nope, still the same.

And if mogrify is old, is there any other way to convert a batch of images and replacing the old files like mogrify does?

Actually, I found a way to do it like this:

mogrify -gravity NorthWest -chop 1x1 *.png
montage -mode concatenate *.png -tile 5x2 -background none 1.png
convert 1.png -gravity NorthWest -background black -splice 1x1 1.png

Basically, it cuts the left and top edges of each frame (so the edges are not ...

And isn't there a way to use splice with mogrify? Because that would solve this problem just fine.

Not working. It fills all the transparency with black. I tried -background none but that has no effect.
The files are transparent .png so I need to keep that transparency.
