You don't have to do anything extra for that. If you try to access a non-existant URL, the HTTP server will report an error that TIdHTTP than wraps into an EIdHTTPProtocolException exception. You do not have to bother with calling TIdHTTP.Head() first, since you are downloading the images to a TMemoryStream before saving them. You can catch the exception when calling TIdHTTP.Get() by itself, no need to check the ResponseCode at all.


You do not actually need the TImage in order to save the data to file. If you can omit the TImage.Picture.Assign() stage, then the code a bit simpler by eliminating the TJPEGImage altogether (unless you are trying to validate the download files are valid), eg:


This page contains information about the various runtime libraries thatare required to run my software. I distribute programs in this way as I do not likethe bloated packages that result from program with the runtimes bundled. You willfind that my programs are smaller and download faster as a result!


Previously, individual libraries were available fordownload. However, this has sometimes resulted in confusion and extraeffort all round as people were unsure which libraries were required for whichsoftware. Consequently, I have now bundled the most popular librariestogether in one setup file, so that you can install all the libraries atonce. You need only download this library bundle once for any of my applications. Ifyou previously downloaded the Delphi 5 runtime library, you may not need thislibrary at all - only download if you get an error message about VCL50.BPL beingmissing.


If you have problems installing this file, one thing you cantry is to make it safe for install, by right-clicking the Zip file, Properties,and pressing the Unblock button if one is present. Please do this beforeunzipping the Zip file ready for install.


You will need to download Borland's Delphi 4 runtime library in order to runsome of my earlier applications. Although it's quite a big download at 600KB, you onlyneed download it once, and it makes every other package from me and other Delphi authorsmuch more compact. If you get "Missing DLL" messages please seehere.


you need to obtain an updated version of the Microsoft Common Controllibrary. You can do this either by installing Microsoft Internet Explorer (V4 orV5), or by downloading a 400KB update from the Microsoft Website.


If you prefer, you can download the full versions of the Intel Signal andImage processing libraries direct from Intel. These are quite large downloads,but if you are trying to develop software using these libraries, you will probablyneed the full version. However, note that the most recent Intel IPL build may havedropped support for the original Pentium processor, so if you have that processor you mayneed my builds which include that support! If you get an error including:"linked to missing export IPL.DLL:ipRemap" you need to update to the LibraryBundle.


A simple Delphi source unit for using this library is available fordownload, which allows writing of JPEG images from BMPs, and reading either fullsize or scaled down images. If you are intending to develop with this software, please download the full Intel JPEGLibrary (about 1.8MB) to get the full header files, licence agreement etc.


Why have I moved to this library? Three reasons: it doesn't havethe same problems as the Borland implementation when saving the rather larger JPEG filesfound in satellite imaging, it is a lot faster, and it saves about 100KB on each new .EXEyou download.


There are now two versions of this library, the original one that was suppliedby Ed Hand (edhand@worldnet.att.net) as partof a Delphi unit to allow Delphi to read PNG images, and a faster Pentium-optimised onethat will be required for my recent software. As the libraries deliberately havedifferent names, you can use either or both according to the requirements of software youchoose to download.


This is a standard Microsoft library that is present on all Windowssystems. However, it is possible that you do not have the latest version. Ifyou have a problem, I may suggest that you download this version and install it in thesame folder as the program with which you are having the problem. This is likely tobe something using the Intel runtime libraries, as I do not call this library directly. Do not install this library on top of a later version or in your Windowsor Windows\System folder. Make sure you keep a backup copy of any file youreplace. Under normal circumstances, there is no need to downloadand install these libraries. As there are several differing versions of this library, perhaps one maycure problems for you.....but you will need to ask directly as installing theselibraries directly is not advised on later versions of Windows.


Upload your video, select size and frames per second, choose the part of the video you want to convert, and click "Convert to PNG!" button. The tool will display a sequence of PNG images and allow you to download them in a zip archive.


As a wrench-turner my experience jives with this feedback, I have also felt that I was dumped onto a busy GH page with no further instructions about where to click. If I see a GH issue about this, I promise I will click the like button on it.

To download data directly in the browser, you must configure yourCloud Storage bucket for cross-origin access (CORS). This can be donewith the gsutil command line tool, which you caninstall from here.


There are a number of reasons why errors may occur on download, including thefile not existing, or the user not having permission to access the desired file.More information on errors can be found in theHandle Errorssection of the docs.


This article explains how to fix problems with images on websites, such as PNG, GIF, and JPG still images, as well as animated file formats such as animated GIF. If you are experiencing difficulty downloading or viewing images in Firefox, follow the troubleshooting instructions below.


Just download the .zip file attached to the release tag, it contains the .dlls, .so and .a. Externals has an edited version of Skia, with a flat api exclusive to the library. There are instructions for compiling in BUILD.md


  • Note. If this is the first time you are creating a macro, most likely the Developer tab won't be visible in your workbook. In this case, switch to the File tab, click Options > Customize Ribbon. In the right hand part of the window, in the Main Tabs list, select Developer, and then click OK.Give your macro a name, for example SaveSelectedChartAsImage and choose to enable it in your current workbook only:

  • Click the Create button and you will have the Visual Basic Editor open with the outlines of a new macro already written for you. Copy the following macro in the second line: ActiveChart.Export "D:\My Charts\SpecialChart.png"

  • Close the Visual Basic Editor and click the Save As button on the File tab. Choose to save your workbook as Excel Macro-Enabled Workbook (*.xlsm). And that's all, you did it! :)

Now let's run the newly created macro to see how it works. Oh wait... there's one more thing for you to do. You should select the Excel chart that you want to export because as you remember, our macro copies only the active chart. Click anywhere on the chart's border and if you see a light gray border surrounding it, then you did it correctly and your entire graph is selected:


Switch to the Developer tab again and click on the Macros icon. This will open a list of macros in your workbook. All you need to do is to select SaveSelectedChartAsImage and click the Run button:


Attribute VB_Name = "Module1"Sub SaveSelectedChatAsImage()' Within Excel you need to set a reference to the VB script run-time library.' The relevant file is usually located at \Windows\System32\scrrun.dll' To reference this file, load the Visual Basic Editor (ALT+F11)' Select Tools > References from the drop-down menu' A listbox of available references will be displayed' Tick the check-box next to 'Microsoft Scripting Runtime'' The full name and path of the scrrun.dll file will be displayed below the listbox' Click on the OK button.' fso: to get the name of the Excel fileDim fso As New Scripting.FileSystemObject' FS: counter to keep track of multiple imagesDim LocalCounter%, FSSet FS = CreateObject("Scripting.FileSystemObject")LocalCounter = 0Do While FS.FileExists("C:\Users\EJB\Documents\" _& fso.GetBaseName(ActiveWorkbook.Name) & "_" _& "(" & LocalCounter & ").png") = TrueLocalCounter = LocalCounter + 1LoopActiveChart.Export "C:\Users\EJB\Documents\" _& fso.GetBaseName(ActiveWorkbook.Name) & "_" _& "(" & LocalCounter & ").png"End Sub


Thank you for your feedback. To fulfill your task, please open the worksheet, press the PrintScreen button on the keyboard. Then open any Image Editor, e.g. Paint, press Ctrl + V to paste the image from the clipboard and then crop it leaving only the necessary part of the screenshot. 2ff7e9595c
