I understand. Maybe it’s because I didn’t explain it clearly. Maybe it’s because my English is not that good! My project is a software material "file" (such as xxx.bin). It is not an image file (such as bmp png...etc.) but a processed file (such as 0x4000~0x5000 blocks to store each pixel) Corresponding position, 0x7000~0x8000 block stores the pixel values ​​used, sorted and stored) After the software reads the file and then performs the internal calculation of the calculation software, the result will be displayed on the software as a material graphic. The other parts have been parsed, and the "arrangement order" of the remaining pixel value data cannot be solved, so I don't care about the corresponding position of its pixel (the corresponding position has been parsed in the block where it is stored). So my need is the pixel The arrangement has nothing to do with the structure of the graph. I have a rough understanding of the image format you mentioned. So I'm just talking about the arrangement of pixels. It may be that my English is not good. Some of the translations used caused trouble in asking questions. I’m sorry! The illustration is for viewing and understanding. It is drawn using VS according to its stored block pixel data. Otherwise it is just a group of arranged pixel values.

My approach is to first use these pixel data to randomly scramble them. Because I don't know the rules, I try to use RGB, HSB, HSV, HSL, HWB...etc. data. Use their elements to match each other for sorting. See if you can achieve the same sorting order as shown in the picture. I just don’t know the rules. So I tried many ways and asked to see if there are any new ideas and directions! As for the sample code, it is only used in conjunction with the sorting functions of list.OrderBy or ThenBy, etc., so I have not posted it!

I understand! Thanks again for your replies

thank you for your reply That picture is not useless. From left to right is its sorting rule. I have tried RGB, HSB, HSV, HSL single condition, double condition, and even three conditions, and tried to sort them with no results. Later, we will find more HWB, HSI, , JzAzBz, JzCzHz, Oklab, Oklch, Okhsv, Okhsl, Okhwb, CAM02, CAM16..etc. I feel like there are special skills or techniques to achieve it. That’s why I asked. As for Excel, if you have any doubts, you can leave it alone. It only records the Format16bppRgb555 pixel data sorted in the picture. As well as the RGB, HSB, HSV, HSL, HWB, HSI, XYZ, xyY, WXY, LAB, LUV, LCH, LCHab, LCHuv, HSLuv, HPLuv, YPbPr, I recorded. YCbCr, YCgCo, YUV, YIQ, YDbDr, TSL, XYB, IPT, ICtCp, JzAzBz, JzCzHz, Oklab, Oklch, Okhsv, Okhsl, Okhwb, CAM02, CAM16.. and other data!

Hello everyone. I have a project. I want to modify software material images. To sort the pixel values ​​of Format16bppRgb555 image files. It must comply with the software rules for the job. Otherwise, errors will occur. The standard sorting format is shown in the figure. Attached is the Excel file. The Rgb555 value from top to bottom in the "B" column is its sorting rule. The rest of the data is based on my rules for finding him. I can't find the rules after trying some methods. What should I do? image URL： https://drive.google.com/file/d/1JBCBFTwElnbmJcsdWD6qPFmwSSgYPrWA/view?usp=sharing Excel URL： https://docs.google.com/spreadsheets/d/16wp0aLDsF8_Chn1Qh2in-4RAmePoRgWi/edit?usp=sharing&ouid=114357640123304602889&rtpof=true&sd=true
