Usage
-
Importing & Creating Handler
from SQLiteImageHandler.SQLiteImageHandler import ImageHandler
handler = ImageHandler(databasePath = "database.db", tableName = "myimages")
-
Adding an image to the database
handler.addImage(imageName = "Image 1", *handler.imageSelector(path = r"C:\Users\mozancetin\Desktop\myimage1.png"))
-
Saving image from database to computer
# If you want, use a save name like "savedImage" instead of "savedImage.png"
# ..because whatever you write, it will automatically fetch the extension from the database.
handler.getSaveImage(imageName = "Image 1", savePath = r"C:\Users\mozancetin\Desktop\savedImage.png")
-
Updating the image in the database
handler.updateImage(imageName = "Image 1", *handler.imageSelector(path=r"C:\Users\mozancetin\Desktop\myimage2.png"))
-
Deleting an image from database
handler.deleteImage(imageName = "Image 1")
-
Check if image exists in the database
isExists = handler.isImageExists(imageName = "Image 1")
print(isExists)
-
Get bytes of image and extension type
bytesOfImage, extensionType = handler.imageSelector(path=r"C:\Users\mozancetin\Desktop\myimage1.png")
print("Bytes Length: " + str(len(bytesOfImage)) + "\nExtension Type: " + extensionType)
Definitions
init(self,databasePath : str = "database.db", tableName : str = "images") -> None
- Sets the self.databasePath, self.tableName and calls startConnection() func.
startConnection(self) -> None
- Starts the connection with SQLite Database.
imageSelector(self, path : str = None) -> bytesContent[bytes], extensionType[str]
- Selects an image and returns the image's bytes content and extension type.
- bytesContent[bytes]: Bytes content of image.
- extensionType[str]: Extension type like png, jpg or something...
addImage(self, imageName : str, imageBytes : bytes, extensionType : str = "png") -> None
- Adds an image to database.
getSaveImage(self, imageName : str = None, savePath : str = "savedImage") -> None
- Saves the previously saved image in the database as an image to the given path.
isImageExists(self, imageName : str = None) -> isExists[bool]
- Checks if image exists in database by image name.
- isExists[bool]: True if image exists in the database otherwise False
deleteImage(self, imageName : str = None) -> None
- Deletes image by name in database.
updateImage(self, imageName : str = None, newImageBytes : bytes = None, newExtensionType : str = None) -> None
- Updates image by name in database.

TODO's
- Write a readme file
- Add different types of images (Right now just png is supported)
- Add more explanation to functions
- Add deletePhoto, updatePhoto functions
- Raise some errors
- Add Usage to readme
- Upload to pypi
- Write a description of each function for README
- Add some cmd things
