File Loading - JPEG Options | File Loading | JPEG

This tab sets the options for loading JPEG files.

The JPEG library allows you to select how to load JPEG files. JPEG files are always stored as 24-bit (truecolor) images, but the library can automatically dither them to 8-bits for displaying on 256-color devices. This dithering will interfere with editing, however: if you want to edit JPEG files on an 8-bit display, it is best to load them as Truecolor even though they don't look as nice. In other words, on an 8-bit (256 color) display, JPEGs are best loaded for viewing as 8-bit color, but best loaded for conversion or editing as 24-bit (Truecolor). For quick viewing on 8-bit displays, load them as Grayscale.

The Two-Pass Quantization and Dither options apply only if loading as 8-bit color; deselecting either or both will speed the load and conversion to 8-bit, at a sacrifice in appearance. The JPEG load dithering is similar to the Floyd-Steinberg dithering available as an option in the Color Depth dialog box.

The Full, 1/2, 1/4 and 1/8 size options allow you to load a JPEG file at smaller than its actual dimensions. This speeds up loading considerably, and allows you to load files that are too large for your system's memory configuration.

Options | File Loading | WP Graphics

Use this tab to set options for rendering WordPerfect graphic (WPG) files.

Ignore Shadows. If this box is checked, ThumbsPlus will not render object shadows in WPG files. This may speed processing, and may make files easier to edit in other (non-WP) applications.

Ignore Gradient fills. If this box is checked, ThumbsPlus will not render gradient fills. This will greatly speed processing and reduce the size of resultant metafiles (either copied to the clipboard or saved to disk).

Ignore Text objects. Check this box if you don't want text information in WPG files rendered.

Use TrueType fonts only. Check this box to force ThumbsPlus to select a TrueType font for any text in WPG files. This option is meaningless if Ignore Text Objects is checked.

File Loading - True Type Fonts Options | File Loading | True Type Fonts

Use this tab to control the actions taken when ThumbsPlus thumbnails and views TrueType fonts.

Thumbnail Sample Text. This text is used to create the thumbnail for the font. By default, this is blank and the font name alone is used to create the thumbnail.

Include Font Name. Checking this box causes ThumbsPlus to use both the sample text above and the name of the font for the thumbnail.

Window Sample Text. This text is displayed at the bottom of the font view window to show an example of how the text looks with several characters together.

File Loading - PhotoCD Options | File Loading | PhotoCD

This tab selects the options for loading PhotoCD images.

The Size to load section allows you to select the desired size of the loaded image. Note that the horizontal and vertical sizes will be reversed for images stored in portrait orientation.

The Color format section allows you to select the color resolution of the loaded image.

Note: You can select the size to load PhotoCD images on-the-fly by holding down the following keys when double-clicking:

Ctrl Base*4 (1536 x 1024)

Alt Base / 4 (384 x 256)

Ctrl+Alt Base (768 x 512)

File Loading - GIF Options | File Loading | GIF

This tab sets the options for loading GIF files. This tab is not available on Windows 3.1 systems, where only the first image is loaded.

Viewing options. Select how ThumbsPlus displays GIF files.

Final appearance. Only the final appearance of an animated GIF file is displayed; intermediate frames are played in memory, but only the final images shows in the view window.

First image only. The first graphic image from the GIF file is loaded. This was the behavior before version 3.0c, and is the only option available for Windows 3.1.

Play to window. An animated GIF file plays into the view window so you can see the changes as they would appear in Netscape or any other browser. You can set several playing options (below) to control how the animation progresses. Looping (as in Netscape) is not supported; the animation plays only once.

Playing options. Select how ThumbsPlus plays GIF files (options for Play to window).

Disable input waits. GIF files can have blocks which specify that the animation should wait for user input. This option disables those waits.

Disable timed delays. GIF files can have specific timed delays between image or text displays; this option will ignore such delays and play frames as fast as possible.

Ignore text blocks. This option causes ThumbsPlus to ignore any displayable text blocks in the GIF file.

Thumbnail options. Select the disposition of GIF files to use for making thumbnails.

Final appearance. The thumbnail is generated from the appearance of the GIF file after all frames have played.

First image only. Only the first image is used to generate the thumbnail.

File Loading - Raw Options | File Loading | Raw

Raw File Types. Shows a list of defined raw types.

New. Add a new raw type, using the Edit Raw Type dialog box.

Edit. Edit the properties of a defined raw type.

Delete. Removes the currently selected raw type.

Options | File Loading | Raw - Edit Raw Type

Use this dialog box to add a new raw file type, or to modify an existing raw type.

Name. Select a name for the format.

Width. The width of the image, in pixels.

Height. The height of the image, in pixels.

Replicate scan rows. Some raw types (notably some files generated by ocular cameras) store only every other scan line (i.e., the pixel shape is rectangular). This option will cause ThumbsPlus to write each scan line twice, restoring the proper aspect ratio.

Pixel format. Select the style of pixels in the raw image. ThumbsPlus can handle several pixel formats directly:

8-bit gray. Each pixel of the image is represented by a single byte which represents the level of gray. Pixel values range from 0 (black) to 255 (white).
16-bit gray. Each pixel is represented by two bytes, with the least significant byte first (Intel byte order). Pixel values range from 0 (black) to 65535 (white).
16-bit gray (swap). Each pixel is represented by two bytes, with the most significant byte first (Motorola format). Pixel values range from 0 (black) to 65535 (white).
24-bit RGB. Each pixel is represented by three bytes: one byte each for red, green and blue, in that order.
24-bit BGR. Each pixel is represented by three bytes: one byte each for blue, green and red, in that order.
32-bit RGB. Similar to 24-bit RGB, except that each pixel is represented by four bytes. The fourth byte is usually an alpha channel, which is ignored by ThumbsPlus.
32-bit BGR. Like 24-bit BGR, except that a fourth byte is present (usually an alpha channel) which is ignored by ThumbsPlus.

Note: By default, the alpha channel (ignored by ThumbsPlus) is assumed to be the fourth byte in 32-bit RGB or BGR formats. However, if your files are stored in ARGB or ABGR order, you can set the Bytes to Skip at start to one (1), and the Bytes to Skip at end to minus one (-1). This will cause ThumbsPlus to ignore the first byte in each four-byte pixel, rather than the last.

Bytes to skip. Some raw formats contain extra data at the beginning or end of the file, or both. Use these fields to enter the amount of data to skip at the start or end of the file.

Expected file size. Using the entries in the other fields, ThumbsPlus computes the expected size on disk of the defined type and displays it here. For ThumbsPlus to recognize the file, its size much match this value.

Note: In order for ThumbsPlus to recognize a file as a defined raw type, two criteria must be met:

The image information must be defined so that the file size matches the "expected file size" as described above.
The file extension must be defined (using Options | Preferences | File Types) as "equivalent to" the .RAW type.

File Loading - UUdecode Options | File Loading | UUdecode

When to uudecode

On demand only. ThumbsPlus will uudecode files only when double-clicked to view. This limits the times that ThumbsPlus processes the files.

When making thumbnails. ThumbsPlus will uudecode when making thumbnails.

Where to uudecode.

Temporary file. ThumbsPlus will uudecode into a temporary file, which will be removed after the thumbnail is made or image viewed.

Original directory. ThumbsPlus will uudecode into the original directory (where the UUE file resides), using the file name specified in the UUE file.

Specific directory. ThumbsPlus will uudecode into a specific directory, using the file name specified in the UUE file. You can use the Browse button to select a directory.

Delete original file when uudecode is successful. ThumbsPlus will remove the .UUE (or .001) and subsequent (.002, etc.) files after successfully decoding the file. Should the decode produce any warnings or errors, the original will not be removed. This option is not available when decoding to temporary files.

Overwrite existing files with the same name. ThumbsPlus will automatically overwrite any file of the same name. This option is not available when decoding to temporary files.
