Re: from_blob can't find file in /tmp

I suggest that you upgrade to the latest version of ImageMagick and then see if both problems are resolved. If upgrading doesn't fix the tmp file problem, report it to the Scruffy developers. If upgrading doesn't fix the convert problem, then post a link to the input .svg file here so that somebody ...

Re: Newbie getting an exception straight away

I've seen that exception before in an out-of-memory condition. Is the AVI file very long? That method call will read the entire file into memory and convert it to ImageMagick's internal format. Do you plan on modifying the individual frames? If not, and you're just trying to play the AVI's, there's ...

Re: Format conversion in memory buffers (no hard disk r/w)

Not really, unless you want to download the RMagick source code, but they're not all that hard to use. A "blob" is just the image data as if it was in a disk file, except it's in an in-memory buffer. If you call ImageToBlob and write the buffer it returns to disk, then that file is exactly the same ...

Incorrect conversion from MVG to SVG

This is 6.4.9-8 on Ubuntu 8.10, built with librsvg.

Will librsvg help with creating SVG output?

When converting an MVG input file to SVG output, will librsvg help? Or is librsvg strictly for use with SVG input files?

Re: Using IM to create iPhone shine effect

I thought this was an interesting question so I worked up an RMagick program to do the job. Sorry it's not pure ImageMagick but I'm not very clever with the convert command. Perhaps somebody else can convert the RMagick methods to ImageMagick commands and options. Here's the goal image (on the left)...

Re: Removing footer from each page of multi-page pdf

I'm pretty sure you're not going to be able to do with with ImageMagick. IM will convert the PDF to a raster image but not back into a PDF file. Use Google to search for programs that are designed for modifying PDF files.
