    <p>The JPEG Images that ImageIO generated view correctly on windows file explorer, as well as safari webbrowser, but in FireFox, the resampled images are clipped.</p> <p>How do I use ImageIO without corrupting the resamples?</p> <p>The code should resize image keeping aspect ratio, as well as do jpeg compression, the convert it to a byte [] array, which could be written to a socket.</p> <p>some of my code. in this snippet, I tried adding Jui library, but still the same issue.</p> <pre><code>public static BufferedImage imageistream; public void Resample(String child,double width,double height) throws Exception, InvalidFileStructureException, InvalidImageIndexException, UnsupportedTypeException, MissingParameterException, WrongParameterException { String imagePath = ""; if(this.is_mac_unix == true) { imagePath = this.path+"/"+child; } else { imagePath = this.path+"\\"+child; } PixelImage bmp = null; try { bmp = ToolkitLoader.loadViaToolkitOrCodecs(imagePath, true, null); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } Resample resample = new Resample(); resample.setInputImage(bmp); double fixedRatio = width/height; if(((double)bmp.getWidth()/bmp.getHeight()) &gt;= fixedRatio) { resample.setSize((int)width,(int)(bmp.getHeight()/(bmp.getWidth()/width))); } else { resample.setSize((int)width,(int)(bmp.getWidth()/(bmp.getHeight()/height))); } resample.setFilter(Resample.FILTER_TYPE_LANCZOS3); resample.process(); PixelImage scaledImage = resample.getOutputImage(); Processor.imageistream = ImageCreator.convertToAwtBufferedImage(scaledImage); bmp = null; Runtime rt = Runtime.getRuntime(); rt.gc(); } ...

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.
