[C #] how images are stored,

Use ue to open an image and use your hands to show the effect of the card tray.

Can I use C # To create an image editor? How? How do I get the route?

Answer later

Obtain the basic knowledge of the class according to the actual operation:

1. files are stored in binary format. In order to facilitate viewing, the editor only provides a hexadecimal display. The structure of the image document is complex and not easy to display.

2. Each row of a hexadecimal file has a line mark

3. block data may be distinguished by some identifiers.

The above information reminds me of one thing, looking for standards! Find the standard!

The answer should be yes. First come to a standard

The omnipotent Internet tells us that the author of the image editor must follow this standard in the past and present of jpeg.

Bmp:

Size: 52270

Jpg

Size: 2417

The bmp, jpg, and png formats are quite large.

Bmp big vernacular one-five-ten descriptions;

Jpg will be summarized in an overview and described in a brief manner;

The character decides fate. bmp is a long-winded expression. If it is too complicated to expect bmp to do, It will bother you with storage fees (it's all right, but it's all nonsense ), however, computers like this product, because computers are a straight brain. You 'd better tell me what I want to do first, second, and second, so small bmp is very fast to open, however, the bmp of a complex image is powerless, and no one can stand a picture of hundreds of megabytes.

Jpg can refine the expression of bmp into a very short content. The problem arises, and the summary will sacrifice the details. Therefore, jpg is not as small as bmp, But it occupies a very small space after compression. This determines that jpg can play many roles, and Internet transmission requires a small and accurate format. Jpg is more artistic, so jpg is a more advanced format. Parsing jpg is a little complicated. However, users see the efficiency and quality of the overall workload. Therefore, jpg is superior.

The computer or software must have a built-in decoder to parse these formats. When using a video player, we often encounter the problem of updating the decoding package.

There is no difficulty in understanding computer image processing.
