Comparison of bmp files?

梦想与她 提交于 2019-12-22 09:25:00
问题 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! 回答1: 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

问题 I have a simple C# .net web application. In that I'm working with XPS files. I have used the following code private void button1_Click(object sender, EventArgs e) { try { string xpsFile = "D:\\Completed-Form.xps"; xpsToBmp(xpsFile); MessageBox.Show("Done"); } catch (Exception ex) { MessageBox.Show (ex.Message); } } static public void xpsToBmp(string xpsFile) { XpsDocument xps = new XpsDocument(xpsFile, System.IO.FileAccess.Read); FixedDocumentSequence sequence = xps.GetFixedDocumentSequence()

问题 I have this simple code to go through a 24bit color windows bmp file BufferedImage mapa = BMPDecoder.read(new File("maps/map.bmp")); final int xmin = mapa.getMinX(); final int ymin = mapa.getMinY(); final int ymax = ymin + mapa.getHeight(); final int xmax = xmin + mapa.getWidth(); for (int i = xmin;i<xmax;i++) { for (int j = ymin;j<ymax;j++) { int pixel = mapa.getRGB(i, j); if (pixel == 0) { System.out.println("black at "+i+","+j); } } } However, when testing on a completely black image, I

Replacing icon in Windows *.exe from open-source platform-independent Java code

问题 First of all, this is not a duplicate of the very common question of making an EXE from Java classes. I do not need to do that. To solve NetBeans RFE #64612 without manual steps I need a Java (6+) library which can take an existing Windows *.exe file and replace its icon with a substitute in a common format. The executable, which is generic and prebuilt (distributed in binary form), already knows how to load an application-specific config file and then start the JRE with various application

Silverlight 4 BitmapImage - bmp file support

旧城冷巷雨未停 提交于 2019-12-20 07:22:41
问题 MSDN mentions support for PNG and JPG, but many people are trying setSource(file.bmp) and complaining about "Catastrophic failures". Can someone clarify this, is bmp supported or not ? And if not, what is the best way for displaying a bmp in silverlight ? 回答1: BMP is not supported in Silverlight. BMP is a very old and not a very efficient format (compared with PNG & JPG) so they have not bothered to support it. Silverlight only supports JPG & PNG format images. The best way to display them is

Tensorflow: How to encode and read bmp images?

隐身守侯 提交于 2019-12-20 04:21:43
问题 I am trying to read .bmp images, do some augmentation on these, save them to a .tfrecords file and then open the .tfrecords files and use the images for image classification. I know that there is a tf.image.encode_jpeg() and a tf.image.encode_png() function, but there is no tf.image.encode_bmp() function. I know that .bmp images are uncompressed, so I've tried to simply base64-encode, np.tostring() and np.tobytes() the images, but I get the following error when trying to decode these formats:

BMP File line padding issue

[亡魂溺海] 提交于 2019-12-19 17:43:34
问题 So I'm trying to export a .bmp file in C++ code, and I have it working except for one major thing: line padding. I'm not 100% sure on how line padding works, but I know I need it. My algorithm works except for the padding, I manually added padding in a hex editor to my exported image and it worked. But how do I add padding? Here is what I have: //Size of the file in bytes int fileSize = 54 + (3 * width * height); //The sections of the file unsigned char generalHeader[14] = {'B','M',0,0, 0,0,0

C# - Remove Bitmap padding

浪子不回头ぞ 提交于 2019-12-19 11:16:07
问题 I was wondering if there's a way in order to remove the padding generated by the 24 bit Bitmap for each scan line. What I mean is like this : Original [Pure Cyan 24 Bit BMP] : FF FF 00 FF FF 00 FF FF **00 00** FF FF 00 FF FF 00 FF FF 00 Desired output [Removed Padding] : FF FF 00 FF FF 00 FF FF **00** FF FF 00 FF FF 00 FF FF 00 Here's my code for getting the pixel data. Bitmap tmp_bitmap = BitmapFromFile; Rectangle rect = new Rectangle(0, 0, tmp_bitmap.Width, tmp_bitmap.Height); System

How to generate a dynamic GRF image to ZPL ZEBRA print

这一生的挚爱 提交于 2019-12-18 13:17:25
问题 I have a problem. I´m generating a dynamic BMP image and trying to send this to a ZEBRA printer by ZPL commands. I need to convert my BMP to a GRF image. I think that my Hexadecimal extracted by the BMP image isn´t correct. The printed image is blurred and incorrect. This is my code: string bitmapFilePath = @oldArquivo; // file is attached to this support article byte[] bitmapFileData = System.IO.File.ReadAllBytes(bitmapFilePath); int fileSize = bitmapFileData.Length; Bitmap ImgTemp = new

Dealing with padding in a BMP file in C

我是研究僧i 提交于 2019-12-18 07:06:39
问题 I am trying to edit a BMP file in C. My code works for BMP files with no padding but I am having trouble dealing with padding. There are a few other questions on BMP files that I have read but most of them use other languages like C# and Java so I didn't find them very useful. Here is what the pixel array looks like, but much larger: char bmpArray[MAX] = {B,G,R,B,G,R,B,G,R,0,0,0, B,G,R,B,G,R,B,G,R,0,0,0, B,G,R,B,G,R,B,G,R,0,0,0} The zeros are for padding bytes to make each row divisible by 4,
