是否可以在网页上显示.bin图像文件而无需将其转换为jpg / png / gif？

Question

I am able to view the .bin image files using display command in ImageMagick.

display -size 512x512 -depth 32 -equalize gray:<filename>

I was able to convert it to jpg format and then display on a webpage. But I need to display the file without converting it to jpg.

Using php exec() , it was possible to display the file when running the php file on terminal but not on apache web server. Is there a way to display the .bin image file on a web page? Please help me as I have been trying this for many days...

Answer 1

No.

The gray: protocol will only output an image data blob. There is no image headers, and various important meta-data (like size, depth, & etc) are not communicated/transported.

Even display requires you to, at minimum, specify size + depth before it can read the .bin file.

However, if you can communicate the depth & width to the web browser, you can rebuild the image with Javascript & <canvas> tag. But that would be labor intensive, and the load-time results would be unpleasant for end-users.
