Comparison of bmp files?

橙三吉。 提交于 2019-12-06 04:01:05
I want to compare two bmp files. I thought of two approaches: to compare the header as well as the information header of the two files convert the bmp file to binary and then do the above comparison But, I don't know how to start and which will be a better approach. I would be glad if someone could please help me! I don't know on which platform you want to implement this, but here are some code snippets which could be useful: Compare two images with C# This is a snippet to compare 2 images to see if they are the same. This method first converts each Bitmap to a byte array, then gets the hash

Unable to create GD image resource from BMP with MIME type 'image/x-ms-bmp' in PHP

依然范特西╮ 提交于 2019-12-06 03:51:24
I'm trying to create a GD image resource from a BMP image, however I'm having no luck. The BMP image in question was created and saved with Photoshop. I've tried a couple of BMPs I found on the web too, and they gave the same results. getimagesize() tells me the BMP image has an image type of IMAGETYPE_BMP (6) and a MIME type of 'image/x-ms-bmp'. I've tried running the image through imagecreatefromwbmp() and imagecreatefromxbm(), but neither recognise it. I've also tried running it through imagecreatefromstring(), but that errored saying 'Data is not in a recognized format'. I'm running XAMPP

c# PDF to Bmp for free

I am writing a program that uses OCR (tessnet2) to scan an image file and extract certain information. This was easy before I found out that I was going to be scanning attachments of PDFs from an Exchange server. The first problem I am working on is how to convert my PDFs to BMP files. From what I can tell so far of TessNet2, it can only read in image files - specifically BMP. So I am now tasked with converting a PDF of indeterminate size (2 - 15 pages) to BMP image. After that is done I can easily scan each image using the code I have built already with TessNet2. I have seen things using

How to interpret the pixel array in a 1 bpp BMP file

I can't find a way to explain the pixel array in the following situation: I created a BMP image 2x2 pixels with MS Paint on Windows 7. Saved it as monochrome BMP (which I think means BMP with color depth 1 bit per pixel) This is how the image looks like when zoomed it (black pixel, white pixel, white pixel, black pixel) Then I open the bmp with a hex editor and I can see the following info: 00: 424d 4600 0000 0000 0000 3e00 0000 2800 BMF.......>...(. 10: 0000 0200 0000 0200 0000 0100 0100 0000 ................ 20: 0000 0800 0000 0000 0000 0000 0000 0000 ................ 30: 0000 0000 0000 0000

I want to draw shapes like rectangles, arrows, text, lines in a BMP or JPG file, using a C# Console Application and GDI+.

Some of these links explains this only for a Windows Forms Application and other links are only for reference (MSDN

C reading bmp files

六月ゝ 毕业季﹏ 提交于 2019-12-05 23:29:10
I'm trying to read in a bmp file to my program and I'm having some issues. After reading in the file if i tell it to print the pBmp->header.fileSize it says 16 but if i look at it in a hex editor the file size portion has F6 7A 10 00 if I modify the value to the correct file size in the hex it will say F6 7A F6 7A 10 00 but that is running into the resv1 which should always be zero. I know that this is only reading in 1 pixel of data another issue I have is when I try to use a while loop to read in the pixels until the end of file I get a segmentation fault. I've literally spent hours googling

How to read a .bmp file identify which pixels are black in Java

Something like the following... except making it work: public void seeBMPImage(String BMPFileName) throws IOException { BufferedImage image = ImageIO.read(getClass().getResource(BMPFileName)); int[][] array2D = new int[66][66]; for (int xPixel = 0; xPixel < array2D.length; xPixel++) { for (int yPixel = 0; yPixel < array2D[xPixel].length; yPixel++) { int color = image.getRGB(xPixel, yPixel); if ((color >> 23) == 1) { array2D[xPixel][yPixel] = 1; } else { array2D[xPixel][yPixel] = 1; } } } } I would use this: public void seeBMPImage(String BMPFileName) throws IOException { BufferedImage image =

Reading bytes from bmp file

孤人 提交于 2019-12-05 08:10:46
问题 How do I read the bytes from a bmp file using C? 回答1: Here's a general-purpose skeleton to just load a binary file, and return a pointer to the first byte. This boils down to "fopen() followed by fread()", but is a ... bit more verbose. There's no error-handling, although errors are checked for and I believe this code to be correct. This code will reject empty files (which, by definition, don't contain any data to load anyway). #include <stdio.h> #include <stdlib.h> static int file_size(FILE
