TRichView.com

I'll fix it in the next update.

Do you use Starter edition of Delphi? This edition does not include command line compilers. The only way to install TRichView in Starter edition is opening packages in IDE one by one and compiling/installing them. Normally, the installer creates packages in default location specified in RAD Studio. ...

FireDAC version of this demo is added (in the same ZIP file)

The demos were updated for compatibility with TRichView 17.3. Now they use functions included in TRVGraphicHandler class, so the code is slightly simplified. The demos include a newer version of DMime (2.8). It is compatible with RAD Studio 10.2 Tokyo. DMime is used to implement base64 encoding in D...

There are no functions for searching text in RVF files, sorry. You need to load them one by one. The slowest procedure is formatting, and SearchText method requires a formatted document. So, if you need a fast search, avoid using SearchText, and create your own procedure for searching text in TRichV...

I am afraid if you add many controls, they will slow down scrolling, and it is unavoidable.
(unless you use ScaleRichView, which displays images of controls instead of controls themselves)

Known problem: in old versions of Delphi, this demo may crash on start.
Workaround: in Unit1.pas, add ActiveX in "uses" and the following code before the final "end.":

You use TDBRichViewEdit. It does some work when the table is moved to an editng state (it stores the field content in a stream, to check later, if it was really changed). The editor moves database into editing state when you type a character or call any editing method (such as InsertText). So, when ...

Sorry, I do not understand the question. Can you explain with more details, what do you want to implement?

Which code did you take as a base? Not all field merging demo projects use item tags.

I received your file and I need some time to test it.

I still do not understand why it may happen. Are these image resized? Also, I which graphic classe is used for them? May be you send me RVF file containing some reasonable count of images, I'll multiply them for testing. And this delay may be caused by your code in events, what's why I ask about rep...

This code is for TRichView 17.3 and newer. No Unicode<->ANSI conversion is needed any more, because all text is Unicode. procedure RemoveFormatting(RVData: TCustomRVData; RemoveMarkers, KeepLinks: Boolean); var i, HypertextStyleNo: Integer; {.............................................................

Does the same problem happen in ActionTest project, or only in your project? Unfortunately, there are no function that return the amount of memory used by the editor. The editor allocates many objects, and nobody calculates their total size. Moreover, because of image caching, the amount of allocate...

Unfortunately no, this function is not implemented.

PS: if you have some other, more sophisticated motion detection library, you can use RVMedia's TRVCamera to get video frames and this library to process them.

For testing, try to increase side of image cache.

Add in DPR file, before creating any form:

uses RVGrCache;

RichViewMaxPictureCount := 10000; // set value greater than the count of pictures in your document
