Join Images C# Overview
The Join Images C# library enables you to merge multiple images into a single composite image with customizable properties.
You can specify the space between images in pixels and choose a space color. The join direction property lets you determine whether the images are combined vertically or horizontally. Additionally, you can set the output format of the merged image to jpg, png, or tiff.
The Join Images C# library is useful for creating cohesive photo collages or visual presentations by seamlessly merging multiple images with customizable gaps and orientation.

Files
File Supported formats: .jpg .jpeg .png .tiff .jfifFiles to be converted. Value can be URL or file content. If used in query or multipart content parameter must be suffixed with index e.g. Files[0], Files[1], Files[2]...
JoinDirection
Collection Default: verticalThe property determines the direction in which individual images are combined into a single image. This property specifies whether the images will be joined in a vertical or horizontal sequence, allowing for flexible layout configurations.
Values: vertical horizontalImageSpacing
Integer Default: 0The property defines the amount of space, in pixels, between individual images when they are combined into a single image.
Range: 0 .. 200SpacingColor
ColorThe property defines the color of the space between individual images when they are combined into a single image.
This property works in conjunction with ImageSpacing to enhance the visual appearance of the composite image by allowing customization of the spacing area's color.
ImageOutputFormat
Collection Default: autoThe property specifies the format of the final image after the individual images have been joined. This property allows you to choose the desired file format for the output image, ensuring compatibility with different use cases and requirements. Additionally, it provides an option to automatically detect the output format based on the format of the joining images.
Values: auto jpg png tiffStoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
