Hello all member,
Please help me to convert images to unsigned char of array 2d data type by java code.

Ex: We have a file Test.png so I want to convert this file to unsigned char Test[][48]={{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,},
{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xF0,0x03,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,}};

Thank you.

You need to explain in more detail what you mean. A file is simply a stream of bytes, so what exactly is your problem?

Hello,

I have a image file. (Test.png) I need algorithms convert this image to unsigned char Test[][]={{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,},
{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xF0,0x03,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,}};

Formatting that.

Thank you for reply me!

Sorry but I still do not understand what you mean by 'convert'. A file (as I said previously) is merely a stream of bytes, so reading it into memory you automatically have an array. What exactly are you trying to do with this file's content?

Use the best guess

Hi,

I have one file test.png I want to convert to array 2d of hexadecimal.

Ex: test.png ---Convert----> unsigned char test [][]={{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,},
{0x00,0x00,0x00,0x00,0x00,0x00,0x00,0xF0,0x03,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,}};

for Example,
Thank you for helping me..!

That is the third time you have posted exactly the same information which gives no explanation of what you mean by "convert". As I said before, if you read the file into memory it will be in an array of bytes, so what do you want to convert it to?

Use the best guess

Oh..!

For example: I have Test.bmp I want to convert it to hexadecimal of array 2d.

There is little point in you continuing to repeat the same sentence which makes no sense. I cannot repeat enough that a file (any file) is a 1-dimensional array of bytes, so what exactly are you trying to convert it into, and how do you expect to make it 2-dimensional?

Use the best guess

I don't know.
