kandi X-RAY | PiClock Summary

PiClock is a Python library typically used in Internet of Things (IoT), Raspberry Pi applications. PiClock has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However PiClock build file is not available. You can download it from GitHub.

A Fancy Clock built around a monitor and a Raspberry Pi. This project started out as a way to waste a Saturday afternoon. I had a Raspberry Pi and an extra monitor and had just taken down an analog clock from my livingroom wall. I was contemplating getting a radio sync'ed analog clock to replace it, so I didn't have to worry about it being accurate. But instead the PiClock was born. The early days and evolution of it are chronicled on my blog If you want to build your own, I'd suggest starting with the overview If you want to use the PiClock on your desktop (not your Pi), I'd suggest using these instructions. All of the extra hardware (IR Remote, GPIO buttons, Temperature, LEDs) are optional, so you can then jump to the install guide Of course you can jump to the hardware guide anytime

            It is advisable to use an XML parser if you have an XML file to deal with. If you have this short fragment only, and you need it to do a one-off task, you may use either of the two regex approaches.

            Extract all matches you want and check which one contains [content], and only return that substring:

            Maximum dy value for XSSFClientAnchor
            Asked 2017-Dec-07 at 01:55

            Using Apache-POI, I'm trying to insert an image in an Excel sheet with an upper-left corner halfway a row with a large font (Calibri-32).
            Using the well-known formulas, I figured out that that the dy1 value within the XSSFClientAnchor should be something like 260,000.
            However, when opening the Excel file, I get an error saying the contents is illeggible.
            Accepting the warning, the image is shown correctly anyway.

            After some tests, I figured out that the maximum value of the dy, without getting an error from Excel, appears to be 190,500.
            The font I use, results in a row height of 55 pixels.
            Halfway the row is therefore 0.5*55*Units.EMU_PER_PIXEL=261,938.

            The same problem occurs when using a smaller font but making the image start near the end of the row.
            In all cases, I get an error if the dy1 has a value greater than 190500.

            Is there anyone who's got a clue?

            I extracted the xml from the xlsx file and I noticed a negative cy value somewhere. I'm not really familar with the xlsx contents but I hope it's useful for somebody:



            Answered 2017-Dec-07 at 01:55

            So we need determining where the negative cy may comes from.

            At first: You should not using constants for BIG_CELL_COLUMN_WIDTH_IN_PIXELS and BIG_CELL_ROW_HEIGHT_IN_PIXELS. Instead do the same as apache poi does and use sheet.getColumnWidthInPixels and ImageUtils.getRowHeightInPixels to calculate width and height.

            And you need set row height according to the fonts height. Else the row remains in default height until Excel is rendering the sheet in view. And in default row height, the dy1 is outside the row if greater than 190500. So it would not be a valid dy1 for this row.

            There is private CTTransform2D createXfrm(XSSFClientAnchor anchor) in XSSFDrawing.java which calculates the xfrm containing the cy. There you can see, that a negative cy only occurs if height + anchor.getDy2() is lower than anchor.getDy1().

            Using XSSF this would be enough. But using SXSSF the calculation of the row height in private CTTransform2D createXfrm(XSSFClientAnchor anchor) using ImageUtils.getRowHeightInPixels(sheet, row) seems to be wrong. I suspect this is because row height is not known already in the sheet because of the streaming manner. So we need a workaround. Set default row height that big as needed for the big font, set the picture then and reset the default row height after that.

            The following works for me:

            How to insert picture into excel using MemoryStream?

            Below are two methods, one uses MemoryStream and the other uses real file on the disk.

            I believe you need to create bitmap image data from stream first

            There's a solution already for that here on Stack Overflow: Byte Array to Bitmap Image I copy-paste the code from the solution:
