2. Query image size: image-image size.
3, anything, first of all, you have to use your own brains, you can't encounter any problems, think of asking questions first, if you don't work hard, you can't learn anything well.
The two questions you asked, if you can take a minute to look at the menu, will solve the problem very simply.
How to draw a rectangle with a specified length and width in PHOTOSHOP? Using the distance track selection tool, in the property bar, select fixed size from the menu behind the style. Then enter a fixed straight line in the back width and height. That's it.
Draw the picture below.

How does VBA draw graphics according to coordinates? Look at an API like Polygon, and you can draw your graphics as long as you set it well.
How do motor vehicles turn around according to regulations? Paragraph 2 of Article 49 of the Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China stipulates that,
Motor vehicles can turn around where there are no signs or markings prohibiting turning around or turning left.
Where U-turn is allowed, motor vehicles can turn around when there are traffic lights, provided that there are neither special U-turn lights nor other traffic signs regulating U-turn;
If there is a traffic sign that clearly indicates that you will turn around during the red or green light, you should turn around during the standardized signal.
When making a U-turn, other vehicles or pedestrians driving normally shall not be obstructed.
Motor vehicles are prohibited from turning around or turning left, as well as railway crossings, crosswalks,
Bridges, sharp bends, steep slopes, tunnels or dangerous sections are not allowed to turn around.

How to draw a straight line according to the specified size with cad? If it is horizontal or vertical, turn on orthogonality, specify the first point, move a little in the horizontal or vertical direction, and directly enter the value. Others can enter coordinates or draw rotations.
How to draw an N-sided figure (drawing) Mathematical term. A plane figure consisting of three or more line segments connected end to end is called a polygon. According to different standards, polygons can be divided into regular polygons and irregular polygons, convex polygons and concave polygons.
A closed figure composed of three or more line segments on the same plane but not on the same straight line, which is connected end to end and does not intersect, is called a polygon. A figure composed of many line segments on different planes that are connected end to end and do not intersect is also called a polygon, which is a generalized polygon.
There are at least three line segments that make up a polygon, and a triangle is the simplest polygon. Each line segment that constitutes a polygon is called an edge of the polygon; The common endpoint of two adjacent line segments is called the vertex of the polygon; The angle formed by two adjacent sides of a polygon is called the inner angle of the polygon; The line segment connecting two nonadjacent vertices of a polygon is called the diagonal of the polygon.
The angle formed by the extension line with one side of the inner angle of a polygon opposite to the other side is called the outer angle of the polygon.
Take an outer corner of the polygon at each fixed point, and their sum is called the sum of the outer corners of the polygon.
Polygons can also be divided into regular polygons and non-regular polygons. Regular polygons have equal sides and equal internal angles.
Polygons are divided into planar polygons and spatial polygons. All vertices of a planar polygon are on the same plane, and at least one vertex of a spatial polygon is not on the same plane with other vertices.
Polygons can also be divided into convex polygons and concave polygons, and all convex polygons are planar polygons.
The sum of the internal angles of 1 and n polygons is equal to (n-2) x180;
Note: This theorem applies to all planar polygons, including convex polygons and planar concave polygons.
2. In a plane polygon, the sum of the internal angles of the equilateral convex polygon and the concave polygon is equal.
3. After the n- polygon passes through a vertex and leads out all diagonals, divide the polygon into (n-2) triangles.
(1) The sum of the external angles of any convex polygon is equal to 360;
(2) The formula for calculating the diagonals of polygons: the number of diagonals of an N-polygon is equal to1/2n (n-3);
(3) A polygon with equal inner edges and angles in a plane is called a regular polygon.
I hope it can help you solve the problem.
The villagers were beaten by the branch secretary. How to punish them according to the regulations? Sentences that constitute minor injuries; Not enough is public security punishment, fine or detention.
How does CAD know the length of a figure and draw it according to the required length? You can test it!
Draw a graph according to the required length: for example, draw a line, first enter the command, specify a point, and enter the length!
1. How to know the length of a graph in CAD? I know there are two methods, one is to measure directly with marks, and the other is to use "tools" and "queries". You can try both methods!
2. How to draw the figure according to the required length? I think it depends on what graphics you want to draw. For example, if it is a square, just enter it directly. If it is other irregular graphics, I want to analyze the specific problems, such as scaling or positioning.
I hope everyone can take out the picture and have a look. Let's continue our discussion!
