Hello, I am trying to get identify to be called via a cgi script. It will identify JPEG GIF and PNG, but as if I try to identify an EPS file I get a delegate failure.

But if I try to run identify from the command line it works just fine.

This is the command I am running...
identify -format "<x>%w ...

just to give some additional iformation. This is how I am doing it with a script currently.

w - The width of the image
h - The height of the image

w and h are derived from an identify operation. What I would like to do is not have the identify operation happen before I do the crop.


if (w/h ...

If I have an image that is 120x60 pixels then this code...
-gravity center -crop 60x60+0+0
Will basically remove the sides from the image leaving a 60x60 square. Very cool.

The problem I have is I want to generalize this and instead of telling it 60x60 I want to say 1x1 or 4x3 or 16x9 and have it ...

Thanks for the reply. I was trying to avoid multiple steps and was looking for a one liner. I may need to do what you have suggested.

I think I am onto a solution. Here is what I have so far. Basically I create my text then apply a -trim then I do a +composite using gravity and geometry.

The ...

How would I determine the width and height of the text I am creating so that I can place an image based on that width and height.

Ok, I think I have a solution to my problem. I am posting here for any that might have the same issue.

convert background.png
\( -size 780x124 xc:none
-font TRAJANPB.TTF -pointsize 60
-fill black
-annotate +28+67 'Journey'
-channel A
-blur 0x3
-font TRAJANPB.TTF -pointsize 60
-fill white ...

Ok, I am still trying to get drop shadowed text over an image. I have come up with the following...

convert background.png
\(-size 780x124 xc:transparent
-font TRAJANPB.TTF -pointsize 60 -fill black
-annotate +28+67 'Journey'
-blur 0x8
\)
+composite
PNG:logo.png

This seems to work except for ...

As I have looked at the example I wonder if the solution is with the -clone operator. I don't really understand how this works though.

This may be overly simple but I can't seem to get my head around the problem. I am able to get the examples found on Anthony's excellent resource working just fine, but I am getting stuck. Here is what I am trying to do.

I would like to create some text and place it on an image. This works ...

Hello,

I have used ImageMagick for about 6 years. I am setting up a new server and I am running this...
convert -font Helvetica -pointsize 40 -fill "#ffffff" -draw "gravity center text 0,0 '9877'" /usr/home/mediaserver/html/clearimage/tmp/.TEMP/verify009TEMP.jpg MIFF:/usr/home/mediaserver/html ...

Does Image Magick have any way to identify Fonts? I know it wasn't possible a year or so ago, but wondered if that kind of functionality might have been added.

If not anyone have a method for identifying font names from the font files?

Thanks for any ideas,


Terry

Hello,

I modified the code from http://www.cit.gu.edu.au/~anthony/graphics/imagick6/thumbnails/ for creating rounded corners so that it could be used all in one command.

On the site I changed this...
convert -size 15x15 xc:white -draw 'circle 0,0 0,14' \
\( xc:none -draw 'circle 0,0 0,12 ...

Yes, I tried that as advised earlier.

Such a minor pixel difference will not be visible, and will be caused purely by the JPEG lossy format. Ignore it, it is not the problem.

Also rotations should be done before shadowing, or your shadow also gets rotated, though with such small rotations this should not be a big problem.


I have ...

It could also be as chrisy states, some color profile changes.


I suggest you get a couple of other sorts of web browsers, IE, FireFox, Opera, etc.. and just take a look to see if the color shift changes from one browser to another.


Thanks for your reply. You are correct, I do not see the ...
