"Inconsistent set of values to create NSBitmapImageRep" Help! - Joseph Duchesne - Sep 30, 2005 05:10 PM
*grumbles about lack of experience in Cocoa*
I am simply trying to create an NSBitmapImageRep with a width of (int)widthPxl and a height of (int)heightPxl and a type of NSJPEGFileType. Here's my code:
Code:
NSBitmapImageRep *tempBitmapImageRep;
tempBitmapImageRep=[[NSBitmapImageRep alloc]
initWithBitmapDataPlanes:NULL
pixelsWide:widthPxl
pixelsHigh:heightPxl
bitsPerSample:8
samplesPerPixel:3
hasAlpha:NO
isPlanar:YES
colorSpaceName:NSDeviceRGBColorSpace
bitmapFormat:NSJPEGFileType
bytesPerRow:0
bitsPerPixel:0];This is giving me "Inconsistent set of values to create NSBitmapImageRep" and I have checked widthPxl and heightPxl. What am I doing wrong? Is there an easier way to create an NSBitmapImageRep with those three parameters? (width, height, jpg)

a) NSJPEGFileType is not a valid argument for bitmapFormat:, read the docs.
b) even if it was, I doubt that you'd be allowed to have a planar image with it, nor that you'd actually want one.
what are you really trying to achieve?

I'm trying to capture an NSView and save it as a JPEG image at a specific size and resolution. One step in this is creating an NSBitmapImageRep of this size.
