I have been studying how to create icons by myself for a long time. If you can make your own icons, you can set personalized icons for any "my computer" or folder.
If you have an idea, try again. So I tried the simplest method: Change the extension! I still remember that a BMP image was successfully converted to JPG, but it was just a modified extension. I thought the icon should be a special image. So I randomly found a jpg image and changed the extension to ico.
Select a folder, change the icon, and select the "icon" you just changed ". An error occurred while saying "file XX does not contain the icon !"! Dizzy! I know it's not that simple. It seems that there are some differences between the icon and the image in terms of structure, but the icon is also an image, and the image will be able to PS, so my PS is forced to open! Dizzy again! It cannot be opened!
What is the difference between ICO and jpg? With this question, I opened their respective attribute boxes. "general" is definitely useless, starting with "summary!
Pixels, resolutions ...... These can be modified with PS ...... Again, there is a "bit depth" attribute! The icon is 32, and the JPG is 24 ...... Meditation. When several JPG images are opened, the depth is 24! It seems that the root cause of their failure to switch with the extension is here. If we increase the JPG bit depth to 32, it's almost the same ......
So I opened PS and saved it as -- JPG. There is no bitwise depth in the options? Is the JPG bit depth only 24? Try again and forcibly convert an ICO to JPG. In this case, it is a JPG with a 32-bit depth. PS ...... Dizzy again! Cannot open. It was confirmed that the JPG bit depth can only be 24! Now, the difference in BIT depth cannot be converted to ico!
Bit depth: What is it? I have been surfing Baidu for a moment, and I have learned a little about it. I have no idea. It suddenly reminds me of BMP, which is a "bitmap". It is almost forgotten because it occupies too much space and is of poor quality. Does bitmap have anything to do with bit depth? Try BMP now. It is the simplest format of the image. It is the image ancestor!
After several BMP images, the result bit depth is still 24! Depressed! PS, open a JPG file, save it as, select BMP, and select the option: Select 32 bits, success! The JPG with a bit depth of 24 is successfully converted into a BMP with a bit depth of 32. The difference is no longer. Just change the extension.
Hey! It works. You can create your own icons in the future. Please try again soon!
