I was wondering if anyone can be a bit more specific on this. Of
course
if its a tool I'm not going to use anything that expects to be able
to find
bundle resources, I get that. Basically what I want to do is make a
tool
that is given a path to a folder as a command line argument, then
loads all
the images in that folder into NSImages, then extracts features
from those
images. That is, it loops over all the pixels of the image with the
getPixel
method of NSBitmapImageRep and pulls out color histogram data and
writes it
to a file. I all ready have a program that does this on a Mac, but
I need to
move it to Solaris, thus trying to get the GnuStep GUI stuff set-up
since
the NSImage classes are in the GUI library. Although, I just
noticed that
the GnuStep version of the NSBitmapImageRep class seems to be
missing the
getPixel method?! Am I missing something here? That seems like *THE*
essential method of the class, and it just doesn't have it. (?)
It isn't probably the essential method of the class, because this
method and related ones have only been introduced with Mac OS X 10.4 :-)
However I admit, it may become an essential method and it is a very
welcome extension.
From NSBitmapImageRep Cocoa header :
#if MAC_OS_X_VERSION_MAX_ALLOWED >= MAC_OS_X_VERSION_10_4
- (void)setColor:(NSColor*)color atX:(int)x y:(int)y;
- (NSColor*)colorAtX:(int)x y:(int)y;
- (void)getPixel:(unsigned int[])p atX:(int)x y:(int)y;
- (void)setPixel:(unsigned int[])p atX:(int)x y:(int)y;
#endif
