Q4. What are the new image display changes and dimension updates added recently along with new buttons?

We have introduced a smarter way to handle large images for a smoother editing experience:

• Canvas-Fit View: Now, uploaded images are automatically resized to fit within the editing canvas. This helps you in seeing the full image in one frame, even for large files. The resized image size becomes the actual working size, which means this is the size you will be working with like editing, blurring and downloading.
• You can check both the original image dimensions and the current image dimensions at the bottom of original image section. This helps you stay aware of what the actual current size of your image is, which in turn ensures better editing accuracy. You can adjust the image size to suit your requirements, whether you want to apply blur on original image size or resized image using the new dimension toggle buttons at the top right corner.
• Dimensions Toggle Buttons: When you upload an image, you will start seeing dimension control buttons at the top right corner of original image section. Using these buttons, you can switch the image size between the canvas-fit size, other available sizes and the original size. These buttons makes the image blurring more precise and accurate by giving you better control. Buttons available are:
1. Original Size: On clicking this, you will get original full size image.
2. Fit to Canvas: This will resize image to fit within the canvas for better visibility and easier editing.
3. "Zoom Out '-'": This will reduce the image size, if it's larger than the canvas-fit size.
4. "Zoom In '+'": This will increase the image size, if it's smaller than the original image size.
• Please note that these buttons will only appear if the uploaded image is larger than the canvas size.
• You can choose any display size, canvas-fit, zoomed in or original. That selected size will remain consistent throughout the blur process and will be used for the final image.
• Image Dimensions Display: Below the Original Image section, you will find two sets of dimensions for the selected image:
1. Original Image Dimensions: It shows the actual dimensions (width * height) of the original uploaded image.
2. Current Image Dimensions: It shows the current size of image currently being used for editing and final output.
