Display icon on LCD

Hi everyone,

I want to display an icon on my LCD but I didn't find some functions that handle ico files.
Is there a library that makes it easy.
PS: I want to display ico stored in SDCARD.

This post might help. It explains how to display a BMP file on an LCD:

Hi PCM programmer,

Thnak you for your reply but I am able to display the bmps on LCD and I want to understand how ico files are organized and if there is some ready-to-use library that handles it.

Thanks

.ICO files are (normally), .BMP files, without the bitmap header. Hence PCM Programmers answer is what you need.
I say 'normally', since in fact data can also be in PNG format, but this is rare unless the data comes from something like a Mac.
So, icons, _are_ bitmaps.
If you want to know the file format of a .ico file, a web search will find dozens of descriptions. I doubt if anyone has bothered to write any form of library for this, since in general it'll be simpler and quicker to just change the data into a raw binary format on the PC, and load this directly to the LCD at the PIC end. Doing as little as possible at the PIC, is always a good way to go....
