Introduction

Organizations ought to have comprehensive management solutions that can help them upload, save, sort, process, and retrieve their content all at a single place. This helps them centrally and remotely manage all their digital assets under one software implementation.


Concept

VIDIZMO, a feature-rich content management solution offers support for all sorts of digital assets such as video, audio, image, document etc, allowing users to not just view/play them back but derive various other valuable information and insights, which is known as metadata, from within your content. This in turn helps to create monetary as well as intellectual value for their content by optimizing its usability, accessibility, search and discovery.


Processing of an Image

When your input image file is processed, there are certain considerations that you need to know about the output file(s) being created:

  • Your original raw file is preserved which enables you to re-use the original file to create as many multiple formats and renditions for different use-cases within the teams. This is a key requirement by organizations for a comprehensive digital asset management solution to let you manage your original assets centrally, while being able to edit, make copies, save versions and distribute them for enhanced collaboration within an enterprise.
  • The input image file is rendered in multiple output formats that can be custom-defined using Encoding Profiles in a portal, more about it is covered later in the article. From the list of supported formats below, the ones with W (Write) and RW (Read-Write) Mode are the formats in which you may export your image in.
  • During processing, VIDIZMO captures information within the image (meta-data) and saves it into content attributes. These attributes are later associated with the image as custom attributes, which are then indexed against the media. These will have their own type in custom attributes called Meta-Data. You can search and access media in your portal using that meta-data such as exposure, date and time, ISO settings, etc. To learn more about search, see: How to Manage Custom Attributes and Understanding Search in VIDIZMO
  • Since media files can have lot of attributes that may not be required for indexing or filtering such as whether the flash was on/off during capture, therefore users have the option to set which custom attributes do they want to index so that they can be made searchable against the media in a portal. 

  • Similarly, text is extracted from the image using OCR (Optical Character Recognition) tool and is linked to the image for enhanced searchability.
  • The default target size of the image remains the same as the source image after it has been processed. For example, if someone uploads a JPEG for 1024*820 px, then the output image will also be the rendered with the same dimensions.
  • While processing and creating various other renditions of the source file, additional information attached to the media is truncated to reduce file size and optimize workflow speed. This is why the data related to EXIF attributes in the input files can vary in comparison to the processed output renditions. However, these EXIF attributes are picked up and added in each of the content file rendition which can then be retrieved via the Media Info screen. To learn more, see: How to view Media Information.
  • There are many underlying characteristics of an image that need to be enhanced in a manner which optimizes a viewer's experience. One such attribute is the exposure and brightness of the surroundings when the image was captured. Optimizing these advanced workflows gives an effortlessly smooth VIDIZMO user experience.
  • After complete processing, image will be uploaded to the configured content provider. To learn more about these providers, see: Storage Providers in VIDIZMO.


Supported File Formats

VIDIZMO employs advanced processing tools to process a huge list of input file formats and render output files as per user requirements.

Here is a list of supported image formats in VIDIZMO, where Modes define whether a format is supported for only Read (R) i.e. input file format, or Write (W) i.e. output file format, or Read-Write (RW) i.e. input as well as output file format.

JPEGRWJoint Photographic Experts Group JFIF formatNote, JPEG is a lossy compression. In addition, you cannot create black and white images with JPEG nor can you save transparency.

Requires jpegsrc.v8c.tar.gz. You can set quality scaling for luminance and chrominance separately (e.g. -quality 90,70). You can optionally define the DCT method, for example to specify the float method, use -define jpeg:dct-method=float. By default we compute optimal Huffman coding tables. Specify -define jpeg:optimize-coding=false to use the default Huffman tables. Two other options include -define jpeg:block-smoothing and -define jpeg:fancy-upsampling. Set the sampling factor with -define jpeg:sampling-factor. You can size the image withjpeg:size, for example -define jpeg:size=128x128. To restrict the maximum file size, use jpeg:extent, for example -define jpeg:extent=400KB. To define one or more custom quantization tables, use -define jpeg:q-table=filename. These values are multiplied by -quality argument divided by 100.0. To avoid reading a particular associated image profile, use -define profile:skip=name (e.g. profile:skip=ICC).

MPEGRWMotion Picture Experts Group file interchange format (version 1)Requires ffmpeg.
MPCRWMagick Persistent Cache image file formatThe most efficient data processing pattern is a write-once, read-many-times pattern. The image is generated or copied from source, then various analyses are performed on the image pixels over time. MPC supports this pattern. MPC is the native in-memory ImageMagick uncompressed file format. This file format is identical to that used by ImageMagick to represent images in memory and is read by mapping the file directly into memory. The MPC format is not portable and is not suitable as an archive format. It is suitable as an intermediate format for high-performance image processing. The MPC format requires two files to support one image. Image attributes are written to a file with the extension .mpc, whereas, image pixels are written to a file with the extension .cache.
MPRRWMagick Persistent RegistryThis format permits you to write to and read images from memory. The image persists until the program exits. For example, let's use the MPR to create a checkerboard:
convert \( -size 15x15 canvas:black canvas:white -append \) \  \( +clone -flip \) +append -write mpr:checkers +delete \  -size 240x240 tile:mpr:checkers board.png

PDFRWPortable Document FormatRequires Ghostscript to read. By default, ImageMagick sets the page size to the MediaBox. Some PDF files, however, have a CropBox or TrimBox that is smaller than the MediaBox and may include white space, registration or cutting marks outside the CropBox or TrimBox. To force ImageMagick to use the CropBox or TrimBox rather than the MediaBox, use -define (e.g. -define pdf:use-cropbox=true or -define pdf:use-trimbox=true). Use -density to improve the appearance of your PDF rendering (e.g. -density 300x300). Use -alpha remove to remove transparency. To specify direct conversion from Postscript to PDF, use -define delegate:bimodel=true. Use >-define pdf:fit-page=true to scale to the page size. To immediately stop processing upon an error, set-define pdf:stop-on-error to true. To set the page direction preferences to right-to-left, try -define pdf:page-direction=right-to-left.

PNMRWPortable anymapPNM is a family of formats supporting portable bitmaps (PBM) , graymaps (PGM), and pixmaps (PPM). There is no file format associated with pnm itself. If PNM is used as the output format specifier, then ImageMagick automagically selects the most appropriate format to represent the image. The default is to write the binary version of the formats. Use -compress none to write the ASCII version of the formats.
PPMRWPortable pixmap format (color)
PSRWAdobe PostScript fileRequires Ghostscript to read. To force ImageMagick to respect the crop box, use -define (e.g. >-define eps:use-cropbox=true). Use -density to improve the appearance of your Postscript rendering (e.g. -density 300x300). Use -alpha remove to remove transparency. To specify direct conversion from PDF to Postscript, use -define delegate:bimodel=true.

PSDRWAdobe Photoshop bitmap fileUse -define psd:alpha-unblend=off to disable alpha blenning in the merged image. Use -define psd:additional-info=all|selective to transfer additional information from the input PSD file to output PSD file. The 'selective' option will preserve all additional information that is not related to the geometry of the image. The 'all' option should only be used when the geometry of the image has not been changed. This option is helpful when transferring non-simple layers, such as adjustment layers from the input PSD file to the output PSD file. This define is available as of Imagemagick version 6.9.5-8. Use -define psd:preserve-opacity-mask=true to preserve the opacity mask of a layer and add it back to the layer when the image is saved.

To define the tile geometry, use for example, -define tiff:tile-geometry=128x128. To specify a signed format, use -define quantum:format=signed . To specify a single-precision floating-point format, use -define quantum:format=floating-point . Set the depth to 64 for a double-precision floating-point format. Use -define quantum:polarity=min-is-black or -define quantum:polarity=min-is-white toggle the photometric interpretation for a bilevel image. Specify the extra samples as associated or unassociated alpha with, for example, -define tiff:alpha=unassociated. Set the fill order with -define tiff:fill-order=msb|lsb. Set the TIFF endianess with -define tiff:endian=msb|lsb. Use -define tiff:exif-properties=false to skip reading the EXIF properties. You can set a number of TIFF software attributes including document name, host computer, artist, timestamp, make, model, software, and copyright. For example, -set tiff:software "My Company". If you want to ignore certain TIFF tags, use this option: -define tiff:ignore-tags=comma-separated-list-of-tag-IDs. Since version 6.9.1-4 there is support for reading photoshop layers in TIFF files, this can be disabled with -define tiff:ignore-layers=true>

TILERTiled imageCreate a tiled version of an image at by tiling a image. Use -size to specify the tiled image size. Tiles are composited on an image background and therefore is responsive to the -compose option. The image is specified similar to TILE:image.miff .
UNIQUEWWrite only unique pixels to the image file.
VIDRWVisual Image DirectoryUsed to create a thumbnailed directory (tiled thumbnails) of a set of images which may be used to select images to view via the display program, or saved to a MIFF or SHTML file.
WINRWSelect image from or display image to your computer screenOnly supported under Microsoft Windows.
XRWSelect image from or display image to your X server screenAlso see the import and display programs.
XCRCanvas image of specified colorAn backward compatible alias for the ' canvas: ' pseudo-file format, used to create a solid color canvas image.



Encoding Profiles

To provide greater flexibility and ease of processing, VIDIZMO processes images on the basis of which Encoding Profiles have been enabled on your portal.

Encoding profiles constitute a group of settings or configuration parameters that help determine the input/output formats of the file along with other key characteristics such as hues and depth of an image. To learn more about them, see: Understanding Encoding Profiles.


These Encoding Profiles are modifiable by the users with the added ability to create their own profiles and obtain as many renditions of an input image file as per organizational requirements.

A sample encoding profile would look like this, allowing users to define parameters like width, height, output format, image sharpening, quality, depth, etc.

{ 

"width": 1280,  

"height": 720,     

"convertTo": {   "extension": "png"    },     

"trim": false,     

"sharpen": true,     

"quality": 100,     

"depth" : 8  

} 

These parameters greatly help you custom-pick characteristics and attributes that you would want your output file to contain, which not only allows to only view your image after upload but transform it completely as per your requirements. For instance: 

  • You can set "convertTo":{ "extension":"jpeg" } for retrieving an image with a jpeg extension.
  • The digits you define as width and height become the pixels to size your image accordingly.
  • Trim parameters helps you automate trimming the edges of a frame for blurred out ends, while sharpen, if set true, visibly makes your picture clearer with more attention to detail.
  • Where the value "100" is the optimum quality for an image, the standard high quality would be around 85 and the minimum lowest quality would be 0. This can vary depending upon the use of the image and the storage considerations that follow in case of large files.
  • Similarly, depth helps you define the hues of the image and their intensity. It is the amount of color information contained in each pixel in an image.  An image with a bit depth of 1 means each pixel in the image can either be black or white, as the pixel can only contain 2 values (1 bit is either "on" or "off"). As the bit depth of an image increases, the colors each pixel can contain increases. The optimal depth for an image is 8, which means 8 bits to define one pixel of an image. This gives us a huge palette of possibilities for our image, and helps enhance its color scheme.
