What works

tested on OS 4.5.11 and 4.5.9

tablet pressure sensitivity (graphire4) works sometimes and sometimes-it doesnt.when i start OC from the command line it works,when i start it from the open with wine file dialog,it doesnt...

everything seems to work for the casual observer,but dont be fooled,it has a fatal bug that prevents it from being usable!

What does not

saving files as *.oci - when you save your file,open canvas suddenly disables your ability to edit it. After you close it,and try to open it again- it gives the following errors:


"could not read the improper event block!"

"detected an error during read-in! err=39!"

and the file loads,but you cannot write on it with any of the brushes.when you try to export it as psd,you get "improper data was detected" error and then "failed to save"

(same happens if you try to save it as psd. Only saving it as jpg,bmp and png seems to work and thus the artist cannot use the sepparate layers)

after all this,if you create a new empty canvas ,you cannot draw on it at all.You have to close open canvas and start it again

visually layers dialog is empty as well (no layer preview)


to put it short- one cannot edit any files that hold the layer information once he saved it once .Either you get errors when you open a previous file and you cant edit it, after that when you try to save the changes,you get errors agan or it closes suddenly and the changes to the file are not applied at all.


all this makes open canvas useless


What was not tested

maybe some of the minor features,things connected with the layers (toggle layers) since that part is empty

Additional Comments

rated bronze since this bug is really bad and OC is very unpredictable

HowTo / Notes

Using the navigation windows and program errors.

Just a quick note here, when using the navigation windows, some may seem unusable. This is usually fixed by restarting OC, but if not, try going to Window menu and restart the item you're having trouble with.

Also, sometimes everything will disappear off OC, such as the workplace. This is usually fixed by moving the program to the left or right desktop.

I have not gotten any errors off the program yet, but contact me if you do.
