Having trouble not being able to see your image after importing?
Typically if the issue is the image resolution you will see the image when it is first imported and then when you zoom only the rectangle border will be visible.

The resolution can also be the issue if the image is visible in the print preview but does not print.

Here are some tips:
  • Saving images as .png files rather than .bmp or .jpg reduces the file size and keeps the quality. PNG files are better for line drawings.
  • Linking rather than embedding the images often helps the issue. If an image is embedded the final file size can make a very large .vcd file (one of the necessary IRRICAD design files).
  • Restarting the computer and then going straight to IRRICAD and loading the problem design may help as other programs aren't holding on to required memory. Then changes can be made to the images as required, for example, un-embedding them.

Image resolution is often the most important criteria - high resolution often equals large file size, unless the file has compression.
Here is an idea of the size of an image based on one fixed for another user:-
7017x9933 pixels – in digital camera terms, that’s around 70 megapixels – i.e. very large.
This was resized to 2123x1500 pixels (~3.2 MP) which displayed perfectly.

Resizing is a simple task and if you don't have a photo editor you can download IrfanView free from the internet (http://www.irfanview.com).
In Irfanview load the image and then go to Image|Information to see the image properties.
Go to Image|Resize/Resample to edit the resolution and save the image as a different file name so as not to overwrite the original image file.
Import the new image into IRRICAD, scale and position correctly.
