    <p><strong>Hey folks!</strong></p> <p>I got this <a href="http://dl.dropbox.com/u/39438681/Bilder/StackOverflow/test6.bmp" rel="nofollow" title="The image">image.bmp</a>. When i read it with all padding included and such i get <a href="http://dl.dropbox.com/u/39438681/Bilder/StackOverflow/scrndmp.PNG" rel="nofollow" title="The result">this</a> result.</p> <p>What am i doing wrong here besides reading the image upside down? I don't find anything relative on Wikipedia or by googling. It seems that after 24 pixels width the image is mirrored 8 pixels. Why!? I don't get it!? How can i fix this!?</p> <p>I'm reading the file with some C++ code on Windows reading the BMP file raw. The image file is monochrome. 1 bit per pixel.</p> <p>Code for showing bitmap data:</p> <pre><code>unsigned int count = 0; // Bit counting variable unsigned char *bitmap_data = new char[size]; // Array containing the raw data of the image for(unsigned int i=0; i&lt;size; i++){ // This for-loop goes through every byte of the bitmap_data for(int j=1; j&lt;256; j*=2){ // This gives j 1, 2, 4, 8, 16, 32, 64 and 128. Used to go through every bit in the bitmap_data byte if(count &gt;= width){ // Checking if the row is ended cout &lt;&lt; "\n"; // Line feed while(count &gt; 32) count -=32; // For padding. if(count &lt; 24) i++; if(count &lt; 16) i++; if(count &lt; 8) i++; count = 0; // resetting bit count and break out to next row break; } if(i&gt;=size) break; // Just in case count++; // Increment the bitcounter. Need to be after end of row check if(bitmap_data[i] &amp; j){ // Compare bits cout &lt;&lt; (char)0xDB; // Block }else{ cout &lt;&lt; (char)' '; // Space } } } </code></pre> <p>Thanks in advance!</p>

    1. COCan you show us the code you're using? We're not going to be very helpful unless you do.

    2. COThere's also [EasyBMP](http://easybmp.sourceforge.net/) which is just for BMP files and with more basic functionality than FreeImage.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
