Usage.

Loading images:

There are three methods to load the files: (1) using the File->Add Images... menu, (2) drag-n-dropping the files from the file manager over the SqCheck viewport and (3) passing the filenames as arguments in the command line.

Notes: the number of command-line arguments is limited, depending on the platform; drag-n-drop automatically sorts the selection case-sensitively and was tested on: Windows Explorer (Windows), Finder (OS X), PcManFM, Thunar, Nautilus and Dolphin (Linux).

SqCheck can take as argument the description of a numbered sequence of files, too. The syntax is like this:

sqcheck <prefix>####<sufix> <start>-<end>

Where the number of sharp characters is the same with the number of digits used to count-off the frames. For example to load all the images from "my_image_0004.png" to "my_image_0120.png", the command is:

sqcheck my_image_####.png 4-120

"Add Images" extends the loaded sequence with the selected files, to clear the memory and load a new sequence from the beginning, the "Clear Images" menu item is provided. In order to load the frames at a lower resolution – to save memory for large projects – the "Load Scale" selector menu should be set to the preferred ratio, before appending new images. The loading time will be a bit greater but less memory will be needed than using full resolution.

Mac OS X users, the executable to run is, assuming you dropped SqCheck.app into /Applications: /Applications/SqCheck.app/Contents/MacOS/sqcheck

Mouse actions:

LMB drag over the viewport or the progress bar navigates through the sequence.

MMB and RMB drag over the viewport are used to pan and, respectively zoom the images, assuming that the menu option "View->Fit Image" is unchecked.

Animation:

The animation functionality is provided by the animation toolbar, located at the bottom of the window, which is pretty straightforward: six playback buttons, one frame rate field and one progress bar. Left and Right keyboard arrows can be used to advance frame-by-frame.
