Re: Extract images from a DbRichViewEdit

See the demo here: https://www.trichview.com/forums/viewtopic.php?f=3&t=11
It sends HTML email using Indy. It processes OnSaveImageImage2 event. This event occurs when saving to HTML. In this event, instead of saving images to files, it collects them in memory, in a collection.

Re: TRichview and Lazarus 1.8.4 CRVData not found

I think it means that your version of Lazarus / FPC is not exactly the same as it was used to compile the trial version. Check the Lazarus About box (menu Help | About Lazarus). The trial was compiled with: Version #: 1.8.4 Date: 2018-07-28 FPC version: 3.0.4 SVN Revision: 57972 Or maybe you applied...

Re: [Help] with Overbyte with RVMedia and streaming microphone data to all connected clients.

This error occurs because you use wrong types for some parameters. The types of var-parameters must be exactly the same as declared.

Re: How to process html Heading (H1, H2 etc) in the editor

The corresponding property is OutlineLevel of paragraph style.

In RichViewActions, you can edit this property for the selected paragraph in the paragraph dialog (page "Advanced", combo box "outline level")

Re: [Help] with Overbyte with RVMedia and streaming microphone data to all connected clients.

TRVAudioPlayer really has PlayAudio method, but it has more parameters: procedure PlayAudio(AStream : TMemoryStream; var ADataSize : Integer; AGUID : TGUID; const AAudioIndex : Word; var AStartTime, ADuration : Longword; var ASamplesPerSec : TRVSamplesPerSec; var ABitsPerSample : TRVBitsPerSample; v...

Re: TRichview and Lazarus 1.8.4 CRVData not found

It's ok that the package manager shows unit names as a strikethrough text: this is not an error, this means that source code is not available. But there are compiled files: - for 32-bit Lazarus, they are in <TRichView Dir>TRichView\Source\lib\i386-win32\ - for 64-bit Lazarus, they are in <TRichView ...

Re: TRichview and Lazarus 1.8.4 CRVData not found

As for Report Workshop, I think it will be ported to Lazarus in this February.
Currently, we paused porting to implement support of "Per Monitor v2" introduced in Delphi 10.3 Rio. When we release it, we will resume porting to Lazarus.

Re: TRichview and Lazarus 1.8.4 CRVData not found

Basically, you need to compile <TRichView Dir>\TRichView\Source\rvpkglaz.lpk and rvpkglaz_dsgn.lpk, and then install rvpkglaz_dsgn.lpk. But there are more packages, so it's much more simple to use project groups. The project group for the trial version is <TRichView Dir>\TRichViewTrialLazarus.lpg Se...

Re: How to control webcam to preview and take photo by RVCamera?

Probably, there are no definite plans about it yet.
There are works with higher priority (FireMonkey, different platforms, ONVIF support)

Re: How to control webcam to preview and take photo by RVCamera?

Some resolution may use encoding unsupported by RVMedia, or not accessible using DirectX method that RVMedia uses.
RVMedia lists all supported video modes.

Re: Now Getting Runtime Error 236 on Delphi Start

One thought... This error may be caused by packages dependent from TRichView which were not recompiled. I.e. if you have some packages that requires TRichView packages, they must be uninstalled before installing TRichView, and recompiled after. A similar problem may occur also for packages dependent...

Re: Now Getting Runtime Error 236 on Delphi Start

There is no known critical errors in this version. Try removing all TRichView-related files and reinstall it again.

Re: How to control webcam to preview and take photo by RVCamera?

No, it's not possible. RVMedia makes snapshots at the same resolution as the current camera video mode.
You can switch camera to high-res mode, make a snapshot, than switch it back.
The demo for switching video modes is in <RVMedia dir>\Demos\Delphi\Cameras\WebCam\
