Basically I want to separate background and foreground so that edges are clear and I can detect contours properly. I have tried many filter and of course thresholds using various parameters. Finally when I was looking on photoshop filters gallery I noticed a filter called Stamp which is giving me desired result(top-right corner). It makes edges clear and I guess use some amount of blur to soft corners. I am not sure how I can obtain same

Timestamps are on higher level in containers like MKV/MP4/TS. The only time related information in H.264 specs afaik are num_units_in_tick/time_scale in VUI that can be used to finding FPS in case of constant frame rate (fixed_frame_rate_flag = 1), and some fields in Picture

A few header files and xml files are generated during build (using gnu make). If it matters the header files are generated based on xml files. I want to search for a keyword in header file that was last modified after a time instance ( Its my start compile time), and similarly xml files, but separate grep queries. If I run it on all possible header or xml files, it take a lot of time. Only those that were auto generated.

And it is important that the watermark is in a corner where it will be visible, for example I have seen websites which generates a watermark on the fly, and puts the mark wherever the background of the main image is "the same color" so the watermark sticks out if you know what I mean. Anybody have a good tutorial or article about this? Or know of any function in php which I would need to find the position

The problem is that I cannot select the input element until the template has loaded. Currently, I am just using setTimeout to focus the input 100ms after the template should load, but I want to know if there is a more elegant solution. Also, the autofocus attribute doesn't work, because the template may un-stamp and re-stamp many times. Right now, my code looks something like this (this is inside a polymer element definition):

When the documents are completed signing, Docusign inserts the EnvelopeID at the top of the resulting PDF document. This results in the EnvelopeID covering critical document information. We need to REMOVE this envelopeID from the document, or at the very least move to the bottom of the page. Our account has the "Envelope ID Stamp Control" feature enabled and it is selected on the Preferences|Features page, but the EvnelopeID continues to appear at the top of

I have an existing pdf document, I'd like to add form fields to it without creating a copy and writing out a new document. 回答1: After further review, the ruling on the field is overturned. Turns out if you form flatten the stamper the fields do not show on the resulting document (because they lack 'appearance' settings). BTW, form flattening prevents further edits of a form field. Now we can add appearance to the form, however, an easier way is to use the TextField class and not
