Hi,
i checked this and i do import ImageAndTextCell.h in my source file.
Any other suggestions why this failes?
Txs!

This will fail on intel if you are not importing ImageAndTextCell.h in
this source file, in which case you would also see a warning for this
line.
The compiler on both ppc and intel will assume that the alpha
parameter is a double if it doesn't see a declaration for the method.
Due to coincidence in the way arguments are passed, it would work
anyway on ppc, but if you were to set a break point on
-[ImageAndTextCell setImage:alpha:] on intel you'd always see 0.0
passed in as the alpha value.
Basically, if you're seeing warnings, get 'em fixed and see if the
problem clears up.

thanks but using png did not solve the problem...
Anyone has other suggestions?

i have the following problem:
in a custom nsoutlineview i have set the cells to display an image.
Everything works fine on a ppc but the images do not show on an
intel machine.
Am i overlooking something?
Help is much appreciated!
- (void)outlineView:(NSOutlineView *)olv willDisplayCell:(NSCell *)
cell forTableColumn:(NSTableColumn *)tableColumn item:(id)item
{
NSTableColumn *myColumn;
myColumn = [libraryTableView
tableColumnWithIdentifier:@"Name"];
if (tableColumn == myColumn)
{
NSFont *font = [NSFont controlContentFontOfSize:
11.0];
[(ImageAndTextCell*)cell setFont:font];
if( [[item objectForKey:@"Name"]
isEqualToString:kMainLibraryName])
{
[ (ImageAndTextCell*)cell setImage: [self
iconOfSize:16
fromImage:[ NSImage imageNamed: @"MainLibrary.tiff" ] alpha:1.0]] ;
}
}
}
- (NSImage *)iconOfSize:(int)size fromImage:(NSImage *)image alpha:
(float)alpha
{
if(!image)
return nil
NSImage *icon = [[NSImage alloc] initWithSize:NSMakeSize
(size,size)];
[icon lockFocus];
[[NSGraphicsContext currentContext]
setImageInterpolation:NSImageInterpolationHigh];
[image drawInRect:NSMakeRect(0,0,size,size)
fromRect:NSMakeRect(0,0,[image
size].width,[image size].height)
operation:NSCompositeSourceOver
fraction:alpha];
[icon unlockFocus];
return [icon autorelease];
}
I would first try another image (e.g. a PNG). If that works, then
the problem will most likely be in the image data itself. I think
it's possible that TIFF can sometimes be platform-specific.
