Improved the full screen display (slideshow) of directories and archives. A slider has been added to the controller so that you can freely jump to any position. Moreover, you can now see the keyboard assignments for functions in Help. In addition, fixed the problems that WebP images are not displayed and that the marked files cannot be deleted.

- You can now save JPEG format images in a smaller file size (using the mozjpeg library). Therefore, the latest ToyViewer allowed you to save files in HEIC format, WebP format, and even optimized JPEG format. - SVGZ format files can now be read. - Fixed the bug that parameters could not be set properly when saving in WebP format. - Updated the help display function.

(1) Added support for reading and exporting WebP format image files. (2) PhotoCD (pcd) files can be flexibly read even if the size is not strictly specified. (3) Included binaries for Apple M1 (Version 5.7.0). (4) Added support for reading and exporting HEIC format image files (Version 5.7.0).

- Added support for reading and writing HEIC format image files. As a result, the interface of the file export panel has changed. - Included binaries for Apple M1. - The interface has been changed, such as the layout of buttons in the display window. - The GPS and other information contained in the file can now be displayed in the Inspector panel. - Updated the resize panel interface. In particular, it is now possible to specify whether to fill the transparent part during rasterization.

- ToyViewer is now applicable to Dark Mode of macOS 10.14 Mojave. - The interface of the selected area part of the inspector is improved. - There was a phenomenon that mouse cursors of ToyViewer could not be displayed in Mojave. This problem is fixed. - The function of Inspector to select an area on a scaled image can work correctly now.

- Tabs are now available in the windows. When tabs are being displayed, if you do some operations such as change of the color tone or adding of transparent color, new image will be displayed in a new tab instead of in a new window. This function is effective only when the newly displayed image is the same size as the original image. Also, in multiple tabs displayed in one window, the display position and the magnification scale are synchronized. - In order to comply with Apple's security policy ATS (App Transport Security), the function to display the remote file by specifying the URL is removed. - Bug Fix: ToyViewer would hang when the color panel is used to select colors.

- You can see RAR archive files as well as ZIP. ToyViewer can also read a RAR archive split into several files. - New function "Scratch Out" is added, which is something like that painting out the selected area with a pen. - (Bug Fix) On the Save panel, specified extensions were not displayed correctly.

- Help document is included in the application. - When you see image files in a directory in the full-screen mode, you can use scroll gestures on the trackpad to proceed forward / backward. - The Preferences panel doesn't give functions about the behavior of the trackpad any more. They are provided by the System Preferences. - With the Prefereces panel, you can make the resizing knobs inactive, that appear on the image by double-clicking. - Bug Fix: The operations (e.g., replacement of colors, addition of transparency, etc.) sometimes changed the tone of an image. Such behavior is suppressed. - Bug Fix: When a custom icon was appended to a directory, the specified image wasn't drawn on the icon as expected.

- ToyViewer 5.3 can display and save images in WBMP (Wireless Bitmap) format. - The new function "Extension Edge" that enlarges the dimension of an image is added. Extension is done by filling with a solid (or transparent) color, by padding with the most outer pixels, or by stretching out the edge. - The new function is added to make monotone (white or black) images with alpha channel. The transparency is added according to their brightness. - Clip operation without the selected area makes the copy of the image, as if the whole of the pixels is selected. This action is the same as version 5.1.2, but it was prohibited in 5.2.4. - When an image with multi-page (or multi-frame) is displayed, a button appears at the bottom right of the window to activate Multi-Page Inspector. - Bug Fix: When a monochrome image was saved as a PNG image file, its format became PNG with palette. Currently, ToyViewer can correctly save a monochrome image as a monochrome PNG. - Bug Fix: The sub-panel of the preferences that makes ToyViewer the default application of each image format didn't work as expected. - Bug Fix: In the English version, "Height" button of the resizing panel couldn't work.

- ToyViewer 5.2 becomes more secure with SandBox. - You can Undo/Redo the selection on the image. With Command+Dragging, you can exactly specify the size and the location of the selection. In addition, you can move the selection using the arrow keys. - Print Inspector is added. With the inspector, you can specify the way to print each image. Moreover, the bug that causes crush during print setup is fixed. - Mulfunctions with the Retina display are fixed.
