I am developing a program that convert PDF files to TIFF files. I use imagemagick++ and can accomplish the concersion successfully. But the resolution of the multi-page TIFF files is too low. My code follows:
and the file exists on disk, because the program just create it and closed the file handler. The error I got:
Debug assertion failed ... program name ... File: (and this is the strange thing!) f:ddvctoolscrt_bldself_x86crtsrcfstat64.c line:64
Why it displays this path? I did not added this path to project so why it tries to call this file? I have installed VC in different location and running x86 32bit machine.
I already succeed to run test raw_decode.c where I used libtiff.lib and libjpeg.lib also here I used the libraries. I already succeed to open file there using
Code: tif = TIFFOpen(srcfile,"r");
and srcfile = "./images/quad-tile.jpg.tiff".
Well I tried to use different path as "./images/ascii_test.tiff" but this also results in break. Where could be the problem that ascii_test.tiff cannot be opened?
I want to read a folder that contains large number of tif files. (say 1000 tif images) requirement is to read all files and store in a array/array pointer.
I have created TIFF Reader using libtiff in c++. Now I have many tiff files with old-style jpeg compression that has to be read/open using libtiff in c++.
I guess, as "old-style" JPEG compression is deprecated in TIFF, because it was never fully specified. And because of this under-specification, various vendors implemented it in different, incompatible ways. Support was dropped in favor for TIFF compression 7, JPEG.
Unfortunately,old TIFF files using this compression still exists.
I have almost a hundred names in a text file that I want to convert to email addresses and save to another file. I seem to have it working, but it doesn't print the full names in the email prefix. The output I'm looking for is Doe_John@livebrandm, but I'm only getting D_J@livebrandm. I'm not sure what I should specifically be reading up on that applies to this directly.
I just wrote a program for Huffman Encoding, where I take a text file, encode it in the form of 0's and 1's, and save that as another text file. However, this does not solve my purpose as it is taking even more space.
So I want to know how do I convert a text file containing these 0'S & 1's to a binary format.
I have written this to convert this .dat file into .txt file but it is not working well. It create one .txt file and also with content but contain some garbage content also .
I am trying to rewrite a matlab code into c++. It reads a file and do the deresolution on it and convert it to 8 bit.
but the VC++ code does not work for all ranges of max_den and min_den. Specially when the there is a small difference between them. (I tried that range on Matlab, it works)
MATLAB Code:
fid = fopen(ORIGINAL_FILENAME,'r'); A = fread(fid,X*Y*Z,'int32=>int32') D = uint8(255/double(Maximum_Density-Minimum_Density)*(A-Minimum_Density)); A = reshape(D,X,Y,Z); fid=fopen(OUTPUT_FILENAME,'w');
[code].....
For example when actual range of data is [-3023,3072] and the max_den=-3000, min_den=1000, it works well. but when you choose max_den=-1000, min den=1000, it doesn't work properly.The raw file includes 3D data associated with a mhd file. When the range is not wide enough, the converted file becomes messy.
I am having a problem with converting a .txt file into a .bin file. It wokrs but only creating a new file and not being able to actually convert it, i have to do this using the fstream functions. I have already created the files in the project file e.g if i type file . file.txt is in the folder.
a few pointers in building an assembler in C for a 68hc11 micro controller I'm struggling on a way to convert the assembly language in a txt file to s19 format.
I want my program read the file and when encounter any enum type, instead of treating it as a string, I want the program store it in memory as a enum value.
How can I do that?
string s; ifs>>s; s // how to convert it to enum???
I am trying to read an array values from Tmin.txt file. I take array size from user viz. number of raw & column and then, read the following data from Tmin.txt file which look like this:
20 40 20 25 30
20 30 40 20 25
20 40 20 25 30
20 30 40 20 25
30 40 40 30 40
I am using getline, and then converting it to int by using atoi. But my code is not working.
Code : // reading a text file #include <iostream> #include <fstream> #include <string> using namespace std;
The problem is that I want to write a C++ program that converts an ordinary text file into binary and then reads that binary file and converts it to text file so that this text file equals to first text file. I have wrote this code for it.
int main() { string name1 = "first", name2 = "sec", name3 = "third"; int j = 0, k = 0; ifstream ifs(name1.c_str()); // Here I want to read from the ordinary text file (name1).
[Code] .....
Now what the ofs.write(as_bytes(j), sizeof(int)); or ifs.read(as_bytes(k), sizeof(int)); exactly mean?
In practice, the file name1 contains digit 5 and its size is 1 byte. The name2 contains some character/sign like [] and its size is 4 bytes and name3 contains digit 0 and its size is 1 byte, why? I before have created the name1 file in ordinary text file mode.
My machine is Windows 7 32-bit. My compiler is MVS 2012.
I'm looking to convert audio, images, video to base64 in c++, and through many searches on the web I've only seem to come up with string > base64.
When I view a .mp3 file for example, there are many characters there that are not available to be used in my string to encode.
[URL] ....
I have this code set up in my project, and all I want is to be able to give the location of any file and have it encode (could just encode to a string, I can handle writing it to a file), and then give a location to put the decoded file as well.
I have been playing around with .txt and .dat files lately. I only manage to load the files, but I don't seem to be able to load files using a variable.
Also modifying the data after it is imported is also currently problematic. I know how to go about the process without the need to import anything, but whenever I import the data I am having trouble modifying/ editing the ".txt" or ".dat" data.
How to convert an ordinary text file into binary and how to convert that binary file back to a text file so that the first text file equals with the last text file?
I am trying to make a program that will convert a list of binary numbers from a file into decimal and print the decimal to the screen. I have no problem doing the conversion, the problem comes up when our teacher wants the input file in a format as such:
3 10110101 11111111 10101010
The first number is supposed to tell the program how many different 8bit strings it is going to have to convert, and then the following lines are those binary numbers.
I am not very experienced with file inputs, and I know how to open files and read lines in.. The problem is, how to say "ok the first line says 3, so now I have to convert the next 3 lines" . I am assuming it is just a simple loop that I am missing....
