CAD图纸里的标注，想一下把全部标注字体或者字体大小改变怎么办？

尺寸标注的基本规则，怎样修改CAD标注尺寸字体大小

label在c语言中是什么意思

不是关键字啊
自己设置的变量名吧

c语言程序设计窗体

可以的吧，那就要用到Windows程序设计了，利用系统提供的API函数和VC++程序向导，就能设计出一个窗口了。
还有就是整个Windows都是用c写的呢，所以可以编写程序窗口

SWT中Label和CLabel控件的区别

一般在swt中，控件的大小和位置都是以托管得方式交给layout去管理，这是swt推荐的，也是很多具有托管机制的语言（Android，ios）建议的，但是如果你想使用绝对布局，可以用control.setBound(坐标x，坐标y，长度，高度);control就是你的控件

用matlab画等值线图时，怎么使图中等值线标注数值上下对齐？

没办法，clabel里'labelspacing'属性可以调整标注的疏密，加入参数'manual'可以手动指定标注的位置。

CLABEL Contour plot elevation labels.
CLABEL(CS,H) adds height labels to the contour plot specified by H.
The labels are rotated and inserted within the contour lines. CS and H
are the contour matrix output and object handle outputs from CONTOUR,
CONTOUR3, or CONTOURF.

CLABEL(CS,H,V) labels just those contour levels given in
vector V. The default action is to label all known contours.
The label positions are selected randomly.

CLABEL(CS,H,'manual') places contour labels at the locations
clicked on with a mouse. Pressing the return key terminates
labeling. Use the space bar to enter contours and the arrow
keys to move the crosshair if no mouse is available.

CLABEL(CS) or CLABEL(CS,V) or CLABEL(CS,'manual') places
contour labels as above, except that the labels are drawn as
plus signs on the contour with a nearby height value.

H = CLABEL(...) returns handles to the TEXT (and possibly LINE)
objects in H. The UserData property of the TEXT objects contain
the height value for each label.

CLABEL(...,'text property',property_value,...) allows arbitrary
TEXT property/value pairs to specified for the label strings.

One special property ('LabelSpacing') is also available to specify
the spacing between labels (in points). This defaults to 144, or
2 inches.

Uses code by R. Pawlowicz to handle inline contour labels.

Example
subplot(1,3,1), [cs,h] = contour(peaks); clabel(cs,h,'labelspacing',72)
subplot(1,3,2), cs = contour(peaks); clabel(cs)
subplot(1,3,3), [cs,h] = contour(peaks);
clabel(cs,h,'fontsize',15,'color','r','rotation',0)

matlab如何在等高线图中显示等高线数值

代码：% By lyqmath
clc; clear all; close all;
[X,Y] = meshgrid(-2:.2:2,-2:.2:3);
Z = X.*exp(-X.^2-Y.^2);
[C,h] = contour(X,Y,Z);
set(h,'ShowText','on','TextStep',get(h,'LevelStep')*2)
colormap cool
title('By lyqmath', 'FontWeight', 'Bold', 'Color', 'r');结果

如何设置UILabel上的文字居上对齐

在iOS中默认的UILabel中的文字在竖直方向上只能居中对齐，博主参考国外网站，从UILabel继承了一个新类，实现了居上对齐，居中对齐，居下对齐。具体如下：
//
// myUILabel.h
//
//
// Created by yexiaozi_007 on 3/4/13.
// Copyright (c) 2013 yexiaozi_007. All rights reserved.
//

#import
typedef enum
{
VerticalAlignmentTop = 0, // default
VerticalAlignmentMiddle,
VerticalAlignmentBottom,
} VerticalAlignment;
@interface myUILabel : UILabel
{
@private
VerticalAlignment _verticalAlignment;
}

@property (nonatomic) VerticalAlignment verticalAlignment;

@end

//
// myUILabel.m
//
//
// Created by yexiaozi_007 on 3/4/13.
// Copyright (c) 2013 yexiaozi_007. All rights reserved.
//

#import "myUILabel.h"

@implementation myUILabel
@synthesize verticalAlignment = verticalAlignment_;

- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
self.verticalAlignment = VerticalAlignmentMiddle;
}
return self;
}

- (void)setVerticalAlignment:(VerticalAlignment)verticalAlignment {
verticalAlignment_ = verticalAlignment;
[self setNeedsDisplay];
}

- (CGRect)textRectForBounds:(CGRect)bounds limitedToNumberOfLines:(NSInteger)numberOfLines {
CGRect textRect = [super textRectForBounds:bounds limitedToNumberOfLines:numberOfLines];
switch (self.verticalAlignment) {
case VerticalAlignmentTop:
textRect.origin.y = bounds.origin.y;
break;
case VerticalAlignmentBottom:
textRect.origin.y = bounds.origin.y + bounds.size.height - textRect.size.height;
break;
case VerticalAlignmentMiddle:
// Fall through.
default:
textRect.origin.y = bounds.origin.y + (bounds.size.height - textRect.size.height) / 2.0;
}
return textRect;
}

-(void)drawTextInRect:(CGRect)requestedRect {
CGRect actualRect = [self textRectForBounds:requestedRect limitedToNumberOfLines:self.numberOfLines];
[super drawTextInRect:actualRect];
}

@end

在使用时：

lbl_mylabel = [[myUILabel alloc] initWithFrame:CGRectMake(20, 50, 150, 600)];
UIColor *color = [UIColor colorWithPatternImage:[UIImage imageNamed:@"halfTransparent.png"]];//使用半透明图片作为label的背景色
lbl_mylabel.backgroundColor = color;
lbl_mylabel.textAlignment = UITextAlignmentLeft;
lbl_mylabel.textColor = UIColor.whiteColor;
lbl_mylabel.lineBreakMode = UILineBreakModeWordWrap;
lbl_mylabel.numberOfLines = 0;
[lbl_mylabel setVerticalAlignment:VerticalAlignmentTop];
[self addSubview:lbl_mylabel];

matlab等高线图中，如何只画（标注）特定的一条等高线？

clc,clear,close all [x,y]=meshgrid(linspace(-2,2)); z=sin(x)+exp(y); %最简单的等高线 contour(x,y,z) %如果要指定等高线条数 contour(x,y,z,10)%画10条等高线 %如果要显示等高线的值 [c,h]=contour(x,y,z); set(h,'ShowText','on')%显示等高线的值 %如果要指定等高线的值 [c,h]=contour(x,y,z); set(h,'ShowText','on','LevelList',[-.7 -.5 -.3 0 .5 1 2 4 7])%设定等高线的值
