Hi everyone,
I am trying to open a .ras image for a school project and I can't. I've tried imfinfo(), imread(), fopen and fread but I can't really get something out of it. The hint that I have is this.
>> f=fopen('filename');
>> rawdata=fread(f);
>> plot(rawdata(1:2500));
>> plot(rawdata(1:2500)); title('Some raw info of the first 2500 bytes... ')
The info I get from the file is the following:
info =
struct with fields:
Filename: '*******************************'
FileModDate: '17-Mar-2021 21:37:00'
FileSize: 402741
Format: 'RAS'
FormatVersion: [ ]
Width: 640
Height: 480
BitDepth: 8
ColorType: 'indexed'
FormatSignature: 1.5041e+09
Length: 307200
Type: 1
MapType: 1
MapLength: 768

Can you share some more info with imread. What is the message when you use imread?

Hello,
Generally, the inbuilt imread function is used to open .ras files as it supports the SUN Raster file format.
The exact supported .ras file formats are described in detail.
Hope it helps
