[Pharo-project] [ANN] Exif
by Alexander LazareviÄ Nov. 25, 2010

Nov. 25, 2010

Hi! I just uploaded a first hack of an Exif package to squeaksource. http://www.squeaksource.com/Exif.html MIT License. Any contributions are welcome (see current limitations). Haven't tested it on Pharo yet. But there shouldn't be anything special about it. Have fun, Alex >From the project description: This provides code to extract/modify the Exif (Exchangeable image file format) information from/inside media files. - Current limitations: - Works only for TIFF-, JPEG-files - Can't write Exif information - Can't read/write GPS information - Can't read/write Interoperability information - Can't read/write any vendor specific MakerNote - Can't read/write UserComments - Most methods for cooked information (like dateTime) are missing - Examples: "Dump all Exif information from a JPEG-file to the Transcript" Transcript show: (Exif readFromJPEGNamed: 'p2.jpg') printAll; cr. "Get *raw* Exif content for DateTime (a String)" (Exif readFromJPEGNamed: 'p2.jpg') atTagName: #DateTime. "#('2010:11:10 16:56:33')" "Get *cooked* Exif content for DateTime (a DateAndTime object)" (Exif readFromJPEGNamed: 'p2.jpg') dateTime. "2010-11-10T16:56:33+01:00" - Specs: Exif and TIFF <http://www.exif.org/specifications.html> - Disclaimer: This software is provided as is. It is in a very early stage and there are no guaranties that the software will work as expected or advertised. Be sure to use only image files with this software that you have backed up before.

[Pharo-project] Question about MethodContext, tempNames and GC
by Mariano Martinez Peck Nov. 25, 2010

Nov. 25, 2010

Hi. These days, I needed to implement a loop detector for one of my projects, and I started to play a lit with thisContext. I've used it before but not as deep as now. It is AWESOME!!!! Now...I noticed (and I think this was the most awesome thing) that I can not only access to senders and their receivers and methods, but also to the arguments!!! And then I thought... mmmmmm how can I access the arguments of a sender of a sender of .... because I thought they should be garbage collected, but if I can access. Ok, there is when I discover that this information is stored in a DebuggerMethodMap and I guess this guy uses a kind of WeakArray to store them. Now, for my loop detector, I use thisContext to access senders AND I need to access the arguments of a method of a sender. For that I use the method ContextPart >> tempsAndValues The question is....isn't this method quite "fragile"? I mean, doesn't this work ONLY if a GC was not run between thisContext and that context ? I am right ? I need to know this to see if I can trust on this or not. And if I am right, maybe we can modify and add this info in a comment? Thanks Mariano
