I just stumble into a feature (or a bug ?), NSImage TIFFRepresentation
produce RGB TIFF with a layer (when open under Photoshop). Previously
it produce plain RGB TIFF under OS 10.5 and below. This cause some
part of my programs interpret wrong RGB data, expecting 3 bytes
instead of 4 bytes
oftware".
A tiff file has tags in the header identifying the number of colour
planes
and their arangement within the file. Any half decent tiff importer
will
simply skip the alpha channel, if it has no use for it, and only
read the RGB
data.

Here is the snippet of the codes,

Graham, after setDataSource to nil, seems do the trick. No more crashing.
Thanks.

I have a window sending data via NSStream to another app. Whenever I invoke
another modal window, the data stops. Somehow NSStream is block by
NSRunModalForWindow. The code is pretty standard, a snippet of the code,
[NSStream getStreamsToHost:host port:portNumber
I replaced NSDefaultRunLoopMode with NSModalPanelRunLoopMode, it is running
fine now. Open another modal window won't stop network process.
Thanks Graham.

I have think of authorization code but it seems now Apple does not want others
to write into this directory. Better to change code to adapt to new settings.

Hi,
I am attempting to create text control something similar like MS Word "line
spacing" feature. A user complain my App paragraph text lines space is too
much, this is because it is done by using NSString drawInRect:withAttributes:,
not much of any adjustment. CoreText seems to able to do so b

Just tested NSParagraphStyle lineHeightMultiple, the line space expands only.
It is similar to NSParagraphStyle lineSpacing, no negative value possible.
Below is the method what I intended to do,
// lspace - 0.0 neutral , negative value the line height contracts and positive
value line height
17 matches
