Hi, I have recently experienced an interesting behavior of the 'cairo_restore()' function. It doesn't restore the cairo context saved by 'cairo_save()' if an error occurs when executing windows gdi functions. When I used these two functions I assumed that they must provide a transaction like functionality: 'cairo_save()' saves the cairo context while 'cairo_restore()' would restore it even if an error would occur by executing cairo functions between. But this is not the case. If a cairo function fail to execute between,  by failing one of the windows gdi function, then 'cairo_restore()' will not restore the previously saved context. I have experienced such situation for the application I'm working on it. For an unknown reason sometime some windows gdi functions (CreateCompatibleDC(), BitBlt() and other) fail to execute with error code 6 and 8. In this situation the cairo function responsible with that windows gdi function call will set the error status to CAIRO_STATUS_NO_MEMORY and the 'cairo_restore()' will not restore the cairo context. I have noticed that cairo context actually has not been damaged by the failure of the windows gdi function, yet the context is not restored. Also the cairo documentation doesn't mention that 'cairo_restore()' will not restore the context if an error occurs in a cairo function between 'cairo_save()' and 'cairo_restore()'. I would like to propose a change in the 'cairo_restore()' implementation, such that:   a) will restore the previously saved context by 'cairo_save()' even if in an error occurs   b) will return as result the error code generated by any cairo function executed between 'cairo_save()' and 'cairo_restore()'   c) will reset the error status to CAIRO_STATUS_SUCCESS so that any next execution of 'cairo_save()' and 'cairo_restore()' will not exit because of a previous status set to an error code. The function would be something like: int cairo_restore (cairo_t *cr) { ... int result = CAIRO_STATUS_SUCESS; if (cr->status != CAIRO_STATUS_SUCCESS) {     result = cr->status;     cr->status = CAIRO_STATUS_SUCCESS;     if ((cr->gstate) && (cr->gstate->target))     {         cr->gstate->target->status = CAIRO_STATUS_SUCCESS;     } } // if (cr->status) // return; ... return result; } Best regards, Iosif Haidu
