The JPEG driver can output in the 24-bit RGB format and can also output the alpha channel as a Grayscale JPEG image. NOTES-END JPEG XL | .jxl | CHK | CHK | NOCHK | NOCHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a JPEG XL disk file. JPEG XL is a new, follow-on revision of the 1990s JPEG file format. It was ratified in 2022. Bitmap images can be saved in RGB and RGBA modes with support for 8-bit integer, 16-bit integer and 32-bit floating point channels with optional compression.
Options are provided to control the speed and quality of the resulting compressed files. NOTES-END PIC (Softimage) | .pic | CHK | CHK | NOCHK | NOCHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a Softimage PIC file format. The file can either be saved as a 24-bit image (8-bit red, green and blue channels), a 32-bit image (24-bits of RGB and 8-bits of alpha channel) or an 8-bit image containing only the alpha channel. RLE compression is optional but enabled by default. NOTES-END PIX (Maya) | .pix | NOCHK | CHK | NOCHK | NOCHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a Alias compatible PIX file format. This file format is commonly associated with such Alias products as Maya, Explore and PowerAnimator. The file can either be saved as a 24-bit image (8-bit red, green and blue channels) or as an 8-bit image containing only the alpha channel. RLE compression is always enabled. NOTES-END PNG | .png | CHK | CHK | CHK | CHK | CHK | NOCHK NOTES-START PNG (Portable Network Graphics) is a replacement for the GIF format. It is a full-featured (non-LZW) compressed format intended for widespread use.
The list of supported bitmap formats is the same as that described for the Photoshop PSD format, except for no G-Buffer support. RLE compression is optional. NOTES-END PPM | .png | NOCHK | CHK | NOCHK | NOCHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a ‘Portable Pixmap’ (PPM) 24-bit disk file. PPM is a rather simplistic file format that only allows data to be stored in 24-bit (RGB) format without any compression. PPM is used by programs such as Microsoft’s Direct3D.
The PPM driver can output in the 24-bit RGB format and can also output the alpha channel as a RGB PPM image. NOTES-END PSD (Photoshop) | .psd | CHK | CHK | CHK | CHK | CHK | CHK NOTES-START This driver saves bitmap images to a subset of the Adobe Photoshop PSD file format. RLE compression is optional but enabled by default. The channels are output in the following order: R, G, B, Alpha. The following output formats are supported:
If the "Output G-Buffer Data" is enabled then the Photoshop PSD driver will also output "Geometry Buffer" data directly from the core renderer to the .psd file. See the section below which discusses this G-buffer common option. By outputting this data to a .psd file you can load it into Photoshop and perform unusual operations on the file, such as doing depth of field calculations based on the "Z" channel output to the .psd file.
NOTE: The only way to output G-Buffer data to a Photoshop PSD file is to use the "Render Scene To File…" menu entry. You must render directly to a file since the G-Buffer data must flow from the core renderer directly to the Photoshop PSD output driver. You cannot render to a window and then follow up by pressing the "Save" button on the render window to subsequently save the window's image to a Photoshop PSD file.
When the Photoshop PSD driver is selected, the G-Buffer data is output in this order and with these extents:
The most interesting aspect of outputting G-Buffer data to a .psd file is using the "Z Depth" information. For example, you can perform depth-of-field processing whereby pixels are blurred based on the value of "Z" in the .psd file. You can also do z-depth based compositing as a post-process operation, such as adding in lens flare effects (the Okino lens flare system uses the G-Buffer mechanism internally to perform z-depth based compositing). NOTES-END SGI RGB | .rgb, .sgi, .bw, .rgba, .inta | CHK | CHK | NOCHK | NOCHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a Silicon Graphics RGB disk file. It is a complete implementation of the RGB file format, allowing for 24-bit and 32-bit output, alpha channel output, and with optional compression. NOTES-END TIFF | .tif, .tiff | CHK | CHK | CHK | CHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a TIFF disk file. It is a complete implementation of the TIFF RGB file format, allowing for 8-bit, 24-bit and 32-bit output, and with optional compression. By default the image will be output as 24-bit data (8-bit red, green and blue channels) but you can choose from 1-bit to 32-bit output. If 256 or fewer colors are chosen (8-bits or less) then the output image will be stored in color-mapped form. If the 32- bit output mode is selected then the alpha channel will be output along with the image data in TIFF alpha channel format.
The TIFF image is not compressed by default. If you enable the "Compress" checkbox then you can select from 3 compression methods: Adobe Deflate (which is compatible with Adobe products), Deflate and PackBits. NOTES-END Targa | .tga, .targa | CHK | CHK | CHK | CHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a TARGA disk file. It is a complete implementation of the TARGA file format, allowing for 8-bit, 24-bit and 32-bit output, and with optional compression. By default the image will be output as 24-bit data (8-bit red, green and blue channels) but you can choose from 1-bit to 32-bit output. If 256 or fewer colors are chosen (8-bits or less) then the output image will be stored in color-mapped form. If the 32-bit output mode is selected then the alpha channel will be output along with the image data in TARGA alpha channel format. NOTES-END WebP | .webp | CHK | CHK | NOCHK | NOCHK | CHK | NOCHK NOTES-START This driver saves bitmap images to a WebP disk file. WebP was first introduced as a stable release by Google in 2018 as a replacement for the JPEG, PNG and GIF file formats. It is often used for imagery on WEB pages. You may also want to consider 'JPEG XL' as a newer compressed file format ratified in 2022. Files will always be saved in 8-bit RGBA mode (with alpha channel). NOTES-END Windows Bitmap | .bmp, .dib | NOCHK | CHK | CHK | NOCHK | NOCHK | NOCHK NOTES-START This driver saves bitmap images to a Microsoft Windows compatible BMP file. The file can either be saved as a 24-bit image (8-bit red, green and blue channels) or as an 8-bit colormapped image (if 256 or fewer colors are chosen).
This format is not a highly recommended format since no file compression is available, no information can be saved along with the file, and it takes up a considerable amount of memory while the image is being rendered to the file. NOTES-END
