You may then have found a bug where the -density used on a EPS is not saved with the rasterized image.

Check the resulting image with verbose.

It amy also be that PNG has some extra meta tag the IM is not setting to save the image resolution or density.

Post the two images somewhere, and I'll download and try to check them out.

Also what version of IM are you using?

Could it be communication setup/send/shutdown times instead?

Communications are often much slower as they have to get timing issues correctly, delaying the results delivery.

Yes it is posible, but depend on exactly what you are trying to find. The simplist methof would be to make a copy of the image, trash all the unwanted colors, say using -fill white -bordercolor red -draw 'color 0,0 border' to leave just the red colors. Then -trim the image and look at the info: outp...

Sounds like the 'on/off' ratio problem. If this does not match what you are experiencing, then please give us a simple, small example code and images that demonstrates the bug.

While IM may handle long filepaths, many systems and command line shells do not.

A favorite quote of mine is...
FileNames are infinite in length, where infinity is set to 255 chars! - "The Unix File System"


As such it may be a system problem rather than an IM problem.

Resample is used to resize and adjust the resolution settings for images that have already been raserized. It is not used for vector images that was rasterized to a specific density. That -density setting itself sets the appropriate size and resolution of the resulting image. your -resample will do ...

Well first of all the padded area is probably not exactly white or black, as JPEG does not store colors exactly. It ia a lossy format, loading and saving an image using JPEG will slowly degrade the image. To fix that a -fuzz factor will be needed. Next the padding do not go completely around the ima...

That first link is to a UNIX shell script program. This program essentually creates star fields as per the link I gave in a previous response. Basically I use that program to generate 'sparkles' which I then use to create three 'sparkling rose' images. Those are then turned into an animation. I sugg...

I actually don't know, I just know what the solution is. I haven't used it myself as yet. That is why I suggest you look up the include headers for the blob definition.

Use the source Luke! :lol:
