Using Embarcadero C++Builder, does anyone know how to manually load a .bmp file into a TSpeedButton using the Glyph property, setting a path to the image, not with the Object Inspector?
The Glyph property is a TBitmap, so you can use the TBitmap::LoadFromFile() method to load a new glyph from a file:
speedbutton->Glyph->LoadFromFile("filename.bmp");
Note: "Glyph can provide up to four images within a single bitmap. All images must be the same size and next to each other in a horizontal row."

I am new to C++Builder 6, but I have used C++. My question is, how do I set a background for my form? When I open the application I want the background to have a specific image. I tried with Graphics::TBitmap but it says that the image is not valid even if it is bmp.
Graphics::TBitmap *BmpTabla = new Graphics::TBitmap;
try {
BmpTabla->LoadFromFile("board.bmp");
}
__finally
{
delete BmpTabla;
}
Edit: I just changed the picture and worked fine.
Drop TImage component to the form, send it to back of the all controls, set the Align property to alClient.
In runtime
Image1->Picture->LoadFromFile("board.bmp");
The easiest way to have a custom background is to use a client-aligned TImage, like #serge suggested.
Another way is to load the BMP image into a Graphics::TBitmap object (like you are already attempting to do) and then use the Form's OnPaint event to draw the TBitmap onto the Form's Canvas.
The "image is not valid" error means you are trying to load a .bmp file that is not a valid BMP image. Double check the contents of the file.
I want to take a qml I created in the QTCreator and transform it to a bmp image.
what I want in the bmp image is just the items I created.
I read about grabWindow but this is not realy what I want because it takes a snapshot of the screen and not creating bmp image with only the items in the qml.
Thanks
From QML:
youritem.grabToImage(function(result) {
result.saveToFile("something.bmp");
});
Although a bmp image is a bad idea, those things are huge. png is the best candidate for QML stuff, which is usually more "vector-y".
I'm using code blocks with sfml and besides it looking ugly, I'm not sure where to store images. I have to select the exact path by putting it in the project folder in the file system. How do i add images?
Say that your project was in
C:\Users\Me\Documents\MyProj
Then then putting the images in this folder would make them visible to SFML/codeblocks when using only the image name.
If you had an image called image.png then the full path to the image would be
C:\Users\Me\Documents\MyProj\image.png
To get the image into your program you must include
#include <SFML/Graphics.hpp>
And create a texture
sf::Texture Texture1;
And then you can assign this image like
Texture1.loadFromFile("C:\Users\Me\Documents\MyProj\image.png"); //Full path
Texture1.loadFromFile("image.png"); //Relative path
Next you create a sprite
sf::Sprite MySprite
And assign the texture to it
MySprite.setTexture(Texture1);
Finally to draw in the window use
window.draw(MySprite);
Right now I change the icon of a window with this code.
What I want to do though is get the current icon in use by a window. Then put it on a canvas. Then put another image on that (a badge) then save it as ico.
Never tried that, however the follow should work in general (with a lot of fiddling)
WM_GETICON to get the big and small icon.
Convert the icon to something the loader can understand (aka. either a BITMAP or ICO). E.g. How can I save HICON to an .ico file?
Load the image. E.g. Javascript: Render PNG stored as Uint8Array onto Canvas element without Data URI
canvas.drawImage
canvas.mozGetAsFile (Blob) or canvas.mozFetchAsStream (nsIInputStream) using the image/vnd.microsoft.icon mime.
Take the resulting data and reconstruct an icon.
LookupIconIdFromDirectoryEx and CreateIconFromResourceEx
WM_SETICON
I just want to create a program which crops an image and sends the cropped image to some remote location.
I have loaded the image using BitBlt(). I dont know, How to uniformly display all the images ? all of same size. stretching is allowed. I have created a static control and now I want to display all the images inside this static control only...
I am able to display images using STM_SETIMAGE, but the problem is that images are not displayed uniformly. So I thought to resize the images before sending them to SendMessage(). I have tried BitBlt() and StretchBlt() but I dont know why nothing works in my code.
The detailed Code
Any Help, will be appreciated...
Thanks in advance,
You might want to try using StretchBlt() instead of BitBlt(). It allows you to specify the source and destination rectangles which will crop and stretch the image.

If you store your image internally as a DIB, using StretchDIBits() would be my recommendation.
