テキスト(String)を画像(NSImage)化する

簡単にテキストを画像化する方法は２つある。

・drawAtPoint

　　決められたポイントから文字を書き出す

set aText to "Abcひら漢字" set {{x, y}, {w, h}} to imageView1's frame()   set myApp to current application set theSize to myApp's NSMakeSize(w, h) --set fontObj to myApp's class "NSFont"'s userFontOfSize:24.0  --|Font A| set fontObj to myApp's class "NSFont"'s fontWithName:"Osaka" |size|:24.0  --|Font B| set sizeValue to fontObj as list set fontAttribute to (myApp's NSFontAttributeName) as list set attributes to myApp's class "NSDictionary"'s dictionaryWithObjects:sizeValue forKeys:fontAttribute set aString to myApp's class "NSString"'s stringWithString:aText set anImage to myApp's class "NSImage"'s alloc()'s initWithSize:theSize anImage's lockFocus() aString's drawAtPoint:(myApp's NSMakePoint(1, 1)) withAttributes:attributes anImage's unlockFocus() imageView1's setImage:anImage

 

・drawInRect

　　決められた範囲内に文字を書き出す

set aText to "Abcひら漢字" set setSize to 48 set myApp to current application set {{x, y}, {w, h}} to imageView1's frame() set theSize to myApp's NSMakeSize(w, h) --set fontObj to myApp's class "NSFont"'s userFontOfSize:setSize  --|Font A| set fontObj to myApp's class "NSFont"'s fontWithName:"Osaka" |size|:setSize  --|Font B| set sizeValue to fontObj as list set fontAttribute to (myApp's NSFontAttributeName) as list set attributes to myApp's class "NSDictionary"'s dictionaryWithObjects:sizeValue forKeys:fontAttribute set aString to myApp's class "NSString"'s stringWithString:aText set {width:w, height:h} to aString's sizeWithAttributes:attributes  --|大きさを計測| set anImage to myApp's class "NSImage"'s alloc()'s initWithSize:theSize anImage's lockFocus() aString's drawInRect:(myApp's NSMakeRect(1, 1, w, h)) withAttributes:attributes anImage's unlockFocus() imageView1's setImage:anImage

 

drawAtPointは範囲を気にしなくても書き出せるが、drawInRectは書き出す範囲を指示しなければいけない。

逆に言えば、drawAtPointでは結果がどこまで書き出しているかを把握できないが、drawInRectなら把握することができる。

 

どちらを使うかは、その時の状況によるのでしょう。
