Images
The Images parameters enable you to create display settings such as height,
width and watermarks for your full size images and any thumbnail images displayed in the
images gallery and on your records.
To set image parameters:
- Click the Images option in the left hand menu of the Configurator.
- Click the CalmView Images option, the image options are displayed in the right hand pane.
Options may be set for ‘default’, ‘gallery thumbnail’, ‘overview thumbnail’, and ‘record thumbnail’ images:
- Default: When a thumbnail image is displayed as part of a full record view it may be clicked on to open a full size version of the image. The 'default' settings apply to this full size image.
- Gallery Thumbnail: The thumbnail images displayed in the image gallery
- Overview Thumbnail: The thumbnail images displayed in the overview and underview
- Record Thumbnail: The thumbnail images displayed in the full record view
Please note: you must set the image options individually for each of the four ‘types’ of image listed above.
First select the type of image you wish to set parameters for, then set the parameters as follows:
Cached
This parameter is displayed as a tick box and defines whether images are ‘built’
once and stored in a cache for quick access or ‘built’ each time they are
viewed. If the images are to be cached then you need to define a folder
in which to store them. This must be done manually in the CalmView\web.config
file (using a text editor), for example to have your images cached on your C: drive in a folder called ImageCache, add the line:
<add key="ImageCacheDir"
value="c:\ImageCache" />
to the <appSettings> section of the web.config file.
Please note: if you decide to alter images which have been cached, you will need to delete the cached versions of the images to see your changes.
Vertical Alignment and Horizontal Alignment
These parameters refer to the alignment of any watermark text that you may set for your images. The watermark text is set in the parameter below. Select the alignment you require using the drop down menu options provided.
Recompress output
It is possible to set modifications for your images, such as height, width and watermarking (see below). If you do not set modifications for your images they will be displayed as they are, without being compressed. This may be undesirable, for example if your image is a large Tiff file, however if this parameter is ticked the image will be compressed.
Output quality
This parameter is displayed as a percentage, for example 100 = 100%. It is specific to file types which allow quality settings, such as .jpg, .gif and .png files.
Output Format
This parameter is displayed as a drop down picklist; select the appropriate output format for your images from the options available.
Maintain Aspect Ratio
If checked then this parameter will retain the original shape of your images, not distorting them if they do not conform to the specified height and width.
Height and Width
The height and width in pixels for your images. Please note that if no height and width are selected then there is no modification of the image.
Maintain Watermark Aspect Ratio
If checked then this parameter will retain the original shape of your watermark image (see watermark file below), when it is displayed with your images.
Watermark File
You may choose to create a transparent watermark image to be displayed ‘over’ your images. Specify the full filename of your watermark image here (it must be a Portable Network Graphic type; with the extension png) and place the file in the CalmView Configuration folder (usually C:\Inetpub\wwwroot\CalmView\Configuration). Please note: you should use a photo editor to create a transparent file to use as a watermark.
Watermark Text
In addition to, or instead of, using a watermark image you may set some watermark text to display ‘over’ your images. Type the text you require here.
Use Original Image File?
If this box is ticked, CalmView will ignore the above settings (including resizing, format changing, and watermarking) and display the original image file.
