13.4.1.1.5 Import and Export images
wxPropView offers a wide range of image formats that can be used for exporting captured image to a file.
Some formats e.g. like packed YUV 4:2:2 with 10 bit per component are rather special thus they can't be
stored into a file like e.g. offered by the BMP file header. When a file is stored in a format, that does not
support this data type wxPropView will convert this image into something that matches the original image
format as close as possible. This, however, can result in the loss of data. In order to allow the storage of the
complete information contained in a captured image wxPropView allows to store the data in a raw format as
well. This file format will just contain a binary dump of the image with no leader or header information.
However, the file name will automatically be extendended by informations about the image to allow the
restoring of the data at a later time.
All image formats, that can be exported can also be imported again. Importing a file can be done in 3 different
ways:
via the menu (via the Menu Bar: Action -> Load image...) 1.
by dragging an image file into an image display within wxPropView 2.
by starting wxPropView from the command line passing the file to open as a command line parameter
(under Windows® e.g.
wxPropView.exe MyImage.png
followed by [ENTER])
3.
When importing a "*.raw" image file a small dialog will pop up allowing the user to define the dimensions
and the pixel format of the image. When the file name has been generated using the image storage function
offered by wxPropView, the file name will be passed and the extracted information will automatically be set
in the dialog thus the user simply needs to confirm this information is correct.
13.4.1.1.6 Bit-shifting an image
wxPropView shows snapped or live images in the display area of the GUI. The area, however, shows the most
significant bits (msb) of the image in the 8 bit display.
The following image shows how a mid-grey 12 bit pixel of an image is displayed with 8 bit. Additionally, two
shifts are shown.
