Yes .. U can use the alt_up_sd_card_read to read the bitmap file...first of all read the bitmap information.. it contains header info after that only data gets start.. so tats only i have separated the header info after that read the data info .....

hi. i am trying to save a bitmap image to sram from sd card through sopc builder and nios2. my problem is i'm not sure if i can directly use alt_up_sd_card_read to read the file because it is a bitmap image. are they the same with reading text file?

and about this:

can you explain this to me please? this is wrting to pixel memory, right? but how did you come up with this?
