Add .TIFF Import Support to MapDesignerRaster.jar
I exported a TIFF from QIS software and would like to import that format into Map-Designer via the Input button.
According to some research, high quality printing is best suited for the .TIFF format.
I'd like to implement this eventually, but probably won't have time for a while. For now, I would suggest converting to a PNG, as it should give you a similar level of print quality as TIFF. QGIS might be able to export PNG, and if not you can convert TIFF to PNG using an image editor like paint.net.
I have done little Java programming, but how challenging is it for me to implement TIFF support in the code? I guess I need to add another plugin for TIFF support and add TIFF support for types. I am hoping the current import being used supports .TIFF formatting.
From a bit of research, someone said JAI could be imported. https://www.oracle.com/java/technologies/advanced-imaging-api.html
I changed this in MapDesignerRaster.java:
private static final FileChooser.ExtensionFilter[] READABLE_TYPES = {
new FileChooser.ExtensionFilter("All image types", "*.png","*.jpg","*.jpeg","*.jpe","*.jfif","*.gif"),
new FileChooser.ExtensionFilter("PNG", "*.png"),
new FileChooser.ExtensionFilter("JPG", "*.jpg","*.jpeg","*.jpe","*.jfif"),
new FileChooser.ExtensionFilter("GIF", "*.gif"),
new FileChooser.ExtensionFilter("TIFF", "*.tiff") };
private static final FileChooser.ExtensionFilter[] RASTER_TYPES = {
new FileChooser.ExtensionFilter("PNG", "*.png"),
new FileChooser.ExtensionFilter("JPG", "*.jpg"),
new FileChooser.ExtensionFilter("GIF", "*.gif"),
new FileChooser.ExtensionFilter("TIFF", "*.tiff") };
Then relaunched the application, but didn't discover any changes on input or output..I am guessing I need to recompile and build the app..but I don't have the env setup to do Java programming.
When I check the metadata of the TIFF, I get lots more yummy details that are important for printing in high quality, however a PNG would suffice if need bees.

Yes, a library would need to be found and imported to support TIFF. It appears javax.imageio has a TIFF plugin, which would probably make the most sense since javax.imageio is what I'm using now. The bigger issue, though, is that in order to write metadata when you save the map, you first need to load and store that metadata from the input image, which the current code doesn't do.
If you want to implement it yourself and send me the code or submit a pull-request, I'd be happy to incorporate it. You would need the ability to compile the app. Up to you, but personally I doubt that metadata is very important and think a PNG will work fine for your purposes.
