Upcoming Changes for our SQL Plugin

Thursday 25 August 2016 at 9:07 pm
From talks with clients, we got a few cool ideas for our SQL Plugin to make live easier or give you more flexibility.

We get some new method overloads for SQLValueMBS to pass MemoryBlocks for various blob field types there as value. So if you have a memoryblock and you pass it, the value is not first converted to a string (a copy of the bytes) and passed to the plugin. Now it passes the memoryblock directly. In general we want to have all plugin functions taking a block of bytes should accept either string or memoryblock to avoid extra conversions.

To quickly get the content of a blob field, you can now use asBLobMemory and asBLobString. Next the Prepare command on SQLDatabaseMBS now returns a SQLPreparedStatementMBS object, so you don't need to cast it anymore. For ODBC, we set the ODBCAddLongTextBufferSpace option now by default to false.

For SQLFieldMBS and SQLParamMBS we add ReadLongOrLob methods so you can read a blob value and have it be written directly to a file (folderitem) or to a stream. For the stream, you can pass any object of a class implementing the Writeable interface. So binary stream is fine as well as a socket, serial port or textoutputstream. This saves you may be a line of code, but it may help people looking for such a method.

For SQLValueMBS class, we added new methods to pass folderitem, memoryblock or Readable interface, e.g. a binarystream. So you can have the plugin stream from a file to a blob field for you from a file.

Next you can pass all parameters as a Dictionary to SQLCommandMBS. Also you can use a dictionary with Bind method in SQLPreparedStatementMBS, too. So if you have data for new record already in dictionaries, you can pass them to SQL commands. With SQLValueMBS you can now set it with a variant.

Now as we can set values for parameters by variant, we detect the type from the variant. So if the variant has a string, we set the parameter to be a string parameter. The auto detection works so well here, that now for prepared statement the binding of a type is optional. So if you bind values to a prepared statement with newer plugin without specifying the actual type, the bind will now work.

There is one thing to note: Passing a memoryblock or a string without a defined encoding, we take it as bytes (BLOB). If you pass text or a string with define encoding, we pass it as a text value. Please make sure you pass either explicit type or you make sure encoding is defined or not.

Tip of the day: DynaPDF form creation with calculation

Tuesday 23 August 2016 at 11:17 pm
Today I wrote the following example code for a client. This snippet creates four form fields. The last field is read only and has a calculation in javascript attached, so the PDF Viewer can calculate the sum of the three fields above. The example shows a second feature called number formats. The PDF Viewer can than format the number with the given number of digits, dot or comma as decimal or thousands separator and of course with a currency prefix/postfix.
dim y as Double = 50 dim lines() as string lines.Append "var v1 = this.getField(""Val1"");" lines.Append "var v2 = this.getField(""Val2"");" lines.Append "var v3 = this.getField(""Val3"");" lines.Append "event.value = v1.value + v2.value + v3.value;" dim script as string = Join(lines, EndOfLine.UNIX) dim f as integer dim a as integer a = pdf.CreateJSAction(script) f = pdf.CreateTextField("Val1", -1, false, 0, 50.0, y, 200.0, 20.0) call pdf.SetTextFieldValue(f, "50.00", "50.00", pdf.ktaRight) call pdf.SetNumberFormat(f, pdf.kdsNoneDot, 2, pdf.knsMinusBlack, "", false) y = y + 30 f = pdf.CreateTextField("Val2", -1, true, 0, 50.0, y, 200.0, 20.0) call pdf.SetTextFieldValue(f, "100.00", "100.00", pdf.ktaRight) call pdf.SetNumberFormat(f, pdf.kdsNoneDot, 2, pdf.knsMinusBlack, "", false) y = y + 30 f = pdf.CreateTextField("Val3", -1, false, 0, 50.0, y, 200.0, 20.0) call pdf.SetTextFieldValue(f, "200.00", "200.00", pdf.ktaRight) call pdf.SetNumberFormat(f, pdf.kdsNoneDot, 2, pdf.knsMinusBlack, "", false) y = y + 30 f = pdf.CreateTextField("Sum", -1, false, 10, 50.0, y, 200.0, 20.0) call pdf.SetFieldBorderWidth(f, 0.0) call pdf.SetTextFieldValue(f, "350.00 €", "350.00 €", pdf.ktaRight) call pdf.SetFieldFlags(f, pdf.kffReadOnly, false) // This last field calculates sum of other fields // Works only in PDF Viewers supporting JavaScript! call pdf.AddActionToObj(pdf.kotField, pdf.koeOnCalc, a, f) call pdf.SetNumberFormat(f, pdf.kdsCommaDot, 2, pdf.knsMinusBlack, " €", false)
PS: Technically we could also offer this for our FileMaker Plugin if needed.

Show download in a new tab

Friday 12 August 2016 at 10:14 pm
In a Xojo Webapp you can not just provide files for download, you can also put them on links:

dim p as Picture = LogoMBS(500)
dim w as new WebPicture(p)

w.Filename = "image.png"
file = w

myLink.Target = myLink.kTargetNewWindow
myLink.URL = w.URL

myLink is a WebLink object on the web page. File is a WebLink property defined in the webpage.
The link now opens in a new browser window or a new tab. For a PDF or image file, this will show it directly in the browser and not start a new download.

Recent changes for DynaPDF licenses

Saturday 06 August 2016 at 12:11 am
Did you notice recent changes to the licenses and features in DynaPDF?
There were two changes which may have gone unnoticed by licensees of the DynaPDF library:

1. Extracting images is now possible with Lite edition due to the new GetImageObj function. This does not apply to inline images, but to all of the big images and those are usually the ones of interest. e.g. if the PDF is from a scanner and only contains a big JPEG stream, you can get this image with Lite instead of Pro. The Pro version still offers more details with the parser interface where you can see which image is used on which page and with what output size. This allows you to know the display resolution, so you can detect low resolution images.

2. The optimize command moved recently from being part of the PDF/A add-on down to the Pro version. You still need the PDF/A add-on to convert arbitrary PDF files to PDF/A. But if you only need to reduce file size by removing duplicate content (e.g. common fonts or images in merge PDFs), you can now just go with your Pro license. This also applies to scaling down images to reduce file size even more!
The optimize command can be used to fix errors in PDFs as it rebuilds the content streams to make them error free. Especially when you archive emails from various clients, you may want to rebuild them just to make sure they display in the future on all readers.

If you are interested in a license, be sure to contact us with your wishes, so we can see if we can build a nice bundle for you for various licenses or apply any current discount offer.
All features are available for FileMaker, Xojo and Real Studio solutions.

Tip of the day: AppleScript with Properties to pass file path

Thursday 21 July 2016 at 11:57 pm
Today we discussed on how to best get the file path into an AppleScript. We'd like to pass it as POSIX path and no the old Mac path format. And we prefer to use properties to pass values into the script. The advantage is that we can compile once and run several times with different values. Finally putting values in properties avoids any escaping problems when putting a text into a script directly. So here is the final code:

// we have some FolderItem dim f as FolderItem = SpecialFolder.Desktop.Child("test.key") // and build a script dim lines() as string // here we declare a property for the script: lines.Append "property filePath : """"" // and convert path from posix file path to AppleScript path lines.Append "tell application ""Finder""" lines.Append " set f to filePath as POSIX file" lines.Append "end tell" // and use path for Keynote lines.Append "tell application ""Keynote""" lines.Append " activate" lines.Append " set mydoc to open file f" lines.Append "end tell" // compile the script dim s as String = Join(lines, EndOfLine.Macintosh) dim a as new AppleScriptMBS a.Compile s if a.Lasterror <> 0 then MsgBox str(a.Lasterror)+" "+a.Error.BriefMessage end if // fill the property a.ScriptPropertyValue("filePath") = f.NativePath // run it a.Execute if a.Lasterror <> 0 then MsgBox str(a.Lasterror)+" "+a.Error.BriefMessage end if

DynaPDF Optimize Command

Sunday 17 July 2016 at 10:54 am
With the next prerelease of our FileMaker, Xojo and Real Studio plugins we will include DynaPDF 4.0.2.4 and the Optimize command has two big changes: First, it now can now scale down images and reduce the size of PDF files significantly. Second, the license changes and the Optimize command is now included in the Pro license.

For optimize you can specify a few parameters. For each image in the PDF, DynaPDF will check the display resolution of the image. That is not the resolution stored in some metadata with the image, but the actual size the image will be displayed. You can specify the minimum resolution for images to be checked independently for Color, grayscale and 1 bit images. Next you define the resolution you want as maximum for the output images. For example you want to scale down all images with more than 100 dpi and reduce them to maximum 150 dpi. For the filter parameter you can specify the compression you want, e.g. JPEG. Converting images from Flate compression to JPEG with same or lower resolution will of course reduce the file size.

When optimizing PDFs, we can remove private data, invisible paths and create new link names. This further reduces size down and rebuilds the structure of the PDF. While doing the optimize we fix problems in PDF files automatically. Some PDFs which showed error messages when opening in Adobe Reader now open without errors.

Here an example:

The test PDF optimize-before.pdf is created with FileMaker 15 from the product catalog example with a few pictures. Than printed to PDF in FileMaker. Of course you can use whatever test PDFs you like for your own tests. Now we run through and let DynaPDF limit image resolution to 150 dpi. The new PDF optimize-after.pdf is much smaller. From 686 KB down to 89 KB (87% saved).

See yourself:
before vs. after

or when we scale them up at 200%:
before vs. after

We can extract the images and see that FileMaker placed a 816x612 Pixel big JPEG file (optimize-image-before.jpg) there. DynaPDF replaced that with a 206x154 Pixel big (optimize-image-after.jpg). I don't think you see the difference at the target size in the PDF. And 150 dpi is quite good for reading on screen and sending via email. FileMaker probably uses 600 dpi here to make sure it looks good when printing.

If you join FileMaker DevCon in Las Vegas, please visit our booth to try compression on your test PDFs!

Use Raspberry Pi Camera in Xojo

Thursday 14 July 2016 at 3:23 pm
As you may know I have a Raspberry Pi and play with it from time to time. One of my hobby projects got to a state where I can show it to you:

For upcoming 16.4 MBS Xojo plugins, we now have a few classes to work with the camera on a Raspberry Pi. You can query available formats, select one and take pictures. We support both picture objects and directly capturing JPEG data. This way you can request image in right size and compressed and your application doesn't need to do this.
If you like to try, please email me soon.
