2015-07-29Printing: calculate a much more accurate font scale valueGravatar Dirk Hohndel
This simply uses the relative size of the profile. This can result in truly tiny text in print, but at least it's consistent and logical. We could add some minimum value there but I'm not sure that's the right answer, either. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2015-07-28Printing: fix dive lookup for profile generationGravatar Dirk Hohndel
The existing code (and templates) looked up dives by number and then used that as index into the dive table. This worked exactly in one case: if all dives were numbered consecutively starting with 1. While that is not an entirely unreasonable case, it's of course not an acceptable assumption to make. This commit adds the necessary changes to instead look up dives by their unique id. That's what it's there fore, after all. Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
2015-07-28Printing: get the number of pages from the full resolutionGravatar Gehad elrobey
When we calculate the number of pages to print we need to check if the template doesn't define the number of dives per one page, then render as much dives as we can fit in one page. A dive can be broken into many pages. Signed-off-by: Gehad elrobey <gehadelrobey@gmail.com> Signed-off-by: Lubomir I. Ivanov <neolit123@gmail.com>

2015-07-20Printing: check for different printing modesGravatar Gehad elrobey

2015-07-20Printing: change QPrinter to parent class QPaintDeviceGravatar Gehad elrobey
Use general class QPaintDevice to be used for printing and previewing instances, printing uses a QPrinter object while previewing uses a QPixmap instance. We use static_cast to use the needed object.

2015-07-05Printing: retrieve number of dives per page from the template fileGravatar Gehad elrobey
Add special data attribute 'data-numberofdives' in the template <body> with the number of dives per page. This is standard HTML5 specification so it won't corrupt the template file.

Make page size and orientation customizable.

2015-06-19Printing: render the dive profile on top of QWebViewGravatar Gehad elrobey

2015-06-19Printing: fix rendering bug for odd number of divesGravatar Gehad elrobey
Odd number of dives needs extra space from the buttom, so that when we scroll to the last page extra whitespace is shown under the last dive frame, this is fixed by adding a default footer to the base template.
