I use ms powerpoint to hold and store all my screenshots of various things throughout the day using my main laptop. I especially do this for items I purchase on Amazon and Ebay. However, on my tablet I cannot do this since I don't have MS Office on it. So now, I would like to create a rolling image bar that holds/shows all my screenshots made on the tablet and then save them all in one file, like a project. I want to do something very similar to what powerpoint does, but nothing fancy. Just a vertical toolbar that holds/shows all images I made. Is there a component that can help me halfway through this project idea, or can I build something close to what I want to do with the tools/components already built into D11/D12 ? In my vision of such a tool, I have the following: 1. a panel/toolbar 2. an timage 3. button to capture the screenshot(s) 4. add/create a new timage in the toolbar every time I take a screenshot (get from cliboard, etc) 5. scroll up/down inside the toolbar of images that I took thus far 6. a main timage that shows the screenshot I take 7. and if I click on any of the images in the toolbar, that image will show on the main timage 8. save and load buttons All this in the above steps are basically what I do in ms powerpoint.

Hi, I take many photos with my Android phone. And now I need a way to Add some search text to the image so that I can find the photos. With a custom image viewer app I will create in conjunction with the metadata reader/writer, my search method would be to open the phone's Gallary (I don't know how to do this yet) and then enter a search word and only photos that match will show, like the way they do when you are in the Gallary app. I searched around and see references for ccr-exif but it is for Delphi VCL, not FMX/Android. Is there a Delphi unit that provides this or someplace where I can download a working project to accomplish this ? TIA.

Hello! It is required to calculate the illumination of a point in a TPNGImage object, taking into account transparency. I wrote the following algorithm: function GetBrightness(const AImage: TPNGImage; AX, AY: Integer): Integer; var LColor, LTransparentColor: TColor; r, g, b, alpha: Byte; tr, tg, tb: Byte; LDstAlpha: pByteArray; begin LColor := AImage.Pixels[AX, AY]; r := Byte(LColor); g := Byte(LColor shr 8); b := Byte(LColor shr 16); if AImage.Transparent and (LColor <> 0) then begin if (AImage.Header.ColorType in [COLOR_RGBALPHA, COLOR_GRAYSCALEALPHA]) then begin LDstAlpha := AImage.AlphaScanline[AY]; if Assigned(LDstAlpha) then begin alpha := LDstAlpha[AX]; r := Byte(Round(r * alpha/255)); g := Byte(Round(g * alpha/255)); b := Byte(Round(b * alpha/255)); end; end else if AImage.Header.ColorType = COLOR_PALETTE then begin LTransparentColor := AImage.TransparentColor; tr := Byte(LTransparentColor); tg := Byte(LTransparentColor shr 8); tb := Byte(LTransparentColor shr 16); r := Byte(Round(r * tr/255)); g := Byte(Round(g * tg/255)); b := Byte(Round(b * tb/255)); end; end; Result := Round(0.3*r + 0.59*g + 0.11*b); end; Please analyze my algorithm for errors. P.S. Unfortunately, in my test base there are no images with TransparentColor - only with alpha channel. Alexander.

Greetings, I have a TMapView component on my firemonkey (android) form. It gets the map image nicely, and I can scroll, zoom in, etc... I need to be able to save that mapview image to storage on an android app, and I'm having no luck. I can't even copy it to another TImage component. Can anyone help me with this? - How can I save the mapview image to local storage on the android? - How can I copy the mapview image to another image component? I've tried things like image1.assign(mapview1.MakeScreenShot) to copy, and MapView1.MakeScreenShot.SaveToFile(filename), but neither of those work. (Assign doesn't do anything, and SaveTo results in an error. Any help would be appreciated. Thanks!
